vob files to MPEG-2 format to save all the audio and video data, which includes not only the film itself, but also for the menus and buttons with pictures and a variety of sub-picture stream subtitles.

I. Basic Profile II, the definition of three, four logical structure of the logical structure of the structure and related issues 1. Embedded database and storage pools are not synchronized between the problem 2. For the embedded database VOB Question 3. For storage pool per se 4. repair tools and instruments used VOB 5. summarize five, file playback 1. Overview 2. playback VOB file 3. extracted VOB file six ways to import vob file editing software installation prepare . vob files in the data broadcast information. Because. Ifo file on the disc can play properly is critical, so all the. Ifo files are saved a copy of the same name. Bup files. Each DVD disc in video manager in both (VMG), store it in VIDEO_TS.ifo file, save the whole disc information, such as areas in which the disc can be played and so on. Meanwhile, the CD will also be used to display the menu data stored in the VIDEO_TS.vob file, when inserted into the drive when the disc player will first display the menu, most of the audience specified in the scene menu, select subtitles and so on.
Second, the definition of Rational ClearCase provides an open architecture for software configuration management (Software Configuration Management, SCM). ClearCase can manage the process of software development source code and various documents produced by the system. In a broader sense, any kind of item of intellectual assets, as long as can be recorded as a digital form can be managed by ClearCase. ClearCase provides not only access to these intellectual assets, capabilities, and recorded on these assets for all versions of every change. All the versions of ClearCase will be stored in the Versioned Object Base (VOB) in. VOB also retained a number of other project and configuration information, so the VOB can be seen as the ClearCase SCM system's central database. Third, the structure as I said before, you can put VOB as a database system. A database system, the logical and physical structure is completely different, such as a relational database and logic can see is: tables, fields, views, stored procedures, users, and permissions, etc.; may be a series of physical file or disk partition. Understand the logical structure of the database to help us better to use it, and understanding the physical structure of the database in order to better manage it. ClearCase VOB first briefly explain the logical structure, and then focus on the logical structure to describe it.
VOB storage directory
logical structure of data in the VOB there are mainly two: simple data (files and directories and its various versions), complex data (branches, labels, event records, etc.). The structure and format of these data are VOB's Schema of the decision. VOB the Schema can be changed. Increase in a VOB can have some special purpose properties, such as: management VOB, Unified Change Management (Unified change management, UCM) VOB, and the project VOB (PVOB). Also provides features VOB feature level with it (Feature level) related to the use of certain features require changing the VOB feature level. Logical structure of a VOB's files are stored in a physical directory (VOB Storage directory) in. Understanding of each file in this directory will help us better manage VOB. I need to focus on the point here is: Do not use the tools of non-ClearCase files inside this directory or any operation, including file or directory to modify the content and read and write permissions. This could lead to VOB inaccessible. Because although they look like regular files and directories, but ClearCase gives them a lot of additional properties, and general tools is difficult to identify and preserve these properties. Of course, if you commit such a mistake unfortunately, led to VOB can not be accessed, ClearCase provides a range of tools can still help you fix. When using the operating system directory listing command (ls, dir,
CHI Pink Dazzle Flat Iron, etc.) View VOB storage directory, you will see the following:. Pid single text file, the process of recording vob_server number. admin a directory that contains the VOB disk space used. vob_oid single line of text documents, records VOB object identification number, the way in with a UUID. Multiple copies in the ClearCase (MultiSite) environment is used to represent a VOB family. A family usually contains an original VOB VOB and several of its clones VOB. replica_uuid single line of text documents, records the VOB replica UUID, used to distinguish the family in a different copy of the VOB VOB. . Identity a directory in the UNIX system, records the VOB's owner and the owner of the group information for access control. identity.sd a binary file, in Windows, the user records the VOB storage directory's security descriptor. groups.sd a binary file, in Windows systems, the recorded VOB storage directory secondary user group security descriptor. s a directory to store all versions of a file or directory. c a directory, a file or directory to temporarily store a version of s used as a buffer pool. The buffer zone will always be refreshed in the ClearCase was called Scrub. In [CC Admin] have a special chapter on Scrubbing operation. d a directory used to store derived objects. When you compile the source VOB files generated by the target file in ClearCase can be used as a derived object (Derived Object, DO). DO to share these different views can use the same binary object files, thus reducing the redundancy, but also accelerated the speed of compilation. ClearCase to a DO in the first generation is called wink in. This directory will also be the system on a regular basis Scrub. db a directory that contains the VOB using an embedded database system (Raima Database). In addition to versions of files and directories other than the actual copying of data are stored in the database. When you make a reformatvob command, the directory to rename the old version will be preserved the way, just in case. vob_server.conf a text file that is used to configure vob_server some startup information. . Hostname a text file, records the VOB server name. . Msadm_acls ClearCase multi-copy records management server environment, access control lists. This is also necessary to introduce an embedded database (directory d) the physical structure: vob_db.dbd a compiled database Schema, describes the structure of the database. vob_db_schema_version Schema version of a file, use it to match the database compiled a database Schema. vob_db.d0n, vobdb.k0n contents of the database. vista .* database control files and transaction log db_dumper executable db_dumper a system backup. reformatvob will call this backup version if the system directory is not available, to ensure that the database export success. vob_db.str_file string database file used to store long strings.
VOB
From the above structure can be seen, ClearCase is a complex and powerful system. It contains an embedded database and a number of self-storage pool. Mutual cooperation between them can not only provide a simple version management, distributed development can be achieved more, parallel compilation, and other system does not have functions. Therefore, any operation on the VOB must be very careful and planned manner. However,
cheap chi flat iron, in specific applications often be some man-made and the inevitable errors, following some discussion on these issues. ClearCase command of all listed for reference only. Fourth, related issues when users extract a version of a file, the usual operation is like this: 1. User sends a request to the VOB database; 2. Database to find the source code to the appropriate storage pool and check the version number, the request given to a program called Type Manager; 3. Type Manager Cleartext pool cache is not found this version of the document; 4. Type Manager source code from the storage pool for the appropriate version of the file and placed in Cleartext pool; 5. Users are requested from the Cleartext pool in the version of the file so often associated with the VOB problem can be divided into three categories: 1. Embedded database and storage pools are not synchronized between the problem of the emergence of such problems mainly because of VOB database information about storage pool storage pool information and the actual result is inconsistent, such as: VOB database contains the storage pool does not exist, VOB database access control for the storage pool information is not correct, or some storage pool is not in the VOB database records. Cause of these inconsistencies may be due to network problems, unsuccessful backup and recovery, or user error to operate the VOB storage directory the following files or directories. Solve these problems is to VOB database and storage pool information to implement synchronization. (From [SCM503]) shows a typical view_log such errors in the related information. Can see that the system can not find the appropriate source pool or cleartext pool files. We can use checkvob command to detect and repair these problems: checkvob-pool-source / vobstg/vob1.vbs the source code to detect vob1 storage pool problem. checkvob-fix-pool-source / vobstg/vob1.vbs the source code used to repair vob1 storage pool problem. The following is checkvob command on various problem solving method: problem solving: can not find the entire storage pool storage pool directory scanning, reconstruction of the records, no records will be no reference to the storage pool storage pool into the lost + found directory storage pool access control error in the case of user rights to allow reconstruction of the access control information. 2. On the issue when the VOB VOB embedded database embedded database itself when problems arise, you will find a lot of action can not be completed. db_server and vobrpc_server communications and databases are two processes, see their logs help resolve the problem. dbcheck and reformatvob can help you recover from most of the problems. Deeper issues embedded in the database itself is beyond the scope of this article, please refer to document [VOB DB]. Another common problem embedded database is beyond the upper limit of the database caused some VOB files inaccessible. VOB stored in an embedded database record is limited. This may be because there is no disk space, the database file itself or the operating system reaches the upper limit. In Schema 53, the database can store about 224 records, the database file size generally can not exceed 2GB. When the embedded database data files (vob_db.d0n, vobdb.k0n) is too large, you can see the ClearCase database server log db_VISTA error (Error number: -900, -909, -912, -914, -919 , 2). You can further view the database using the command countdb usage, as follows. There are three ways to help you solve this problem: 1. You can remove some of the directories in the VOB to resolve the temporary restrictions, that is, the large VOB split into several smaller VOB; 2. Manually delete VERSION_LABEL_LINK, DOT_DOT / NAMESPACE_DIRECTORY_VERSION_ENTRY, and the number of records OPLOG_ENTRY; 3. The best way is to use or upgrade to Schema54 or more. VOB can be used to upgrade reformatvob command, but this operation generally requires a long, long time. In addition to other large data files, control files, log files, and strings will also affect the file is too large VOB access. Control file and log file size can be db.conf file configuration. Strings file is too large can be detected by sting_report.exe. According to the results of sting_report.exe views and DO remove unused strings, etc., may reduce the file size. 3. On the issue when the storage pool itself rule out the possibility of the above two issues later, VOB there are problems, it may be because the storage pool itself has been compromised, should first check the VOB storage directory information is a text file correct. For example: If the VOB server name changes should be checked. Hostname. As mentioned above, ClearCase VOB storage directory file can not be modified with the general tools. If you do not accidentally modify the Windows browser, a file or directory, it may cause they can not access. If the VOB's root directory, you can not access the VOB. Can be used in Schema53 fix_prot to repair, can be used in Schema54 vob_sidwalk. If the problem persists, the final inspection can be used ck_all_tfd_for_nulls.pl command, if errors are found before the backup can be restored to the damaged storage pool directory, and then run checkvob command, or run a standard ClearCase recovery operations. 4. Repair checkvob VOB tools and instruments used can be found embedded database storage pool and is inconsistent with-fix option that the errors can be fixed. ck_all_tfd_for_nulls.pl storage pool in the text to find the site of injury. It is a system tool, usually in the utils directory. countdb.exe can display the embedded database space usage, usually in the utils directory. string_report.exe embedded database is used to detect the use of string files, usually in the utils directory. db log and vobrpc log files embedded database when there is a problem suspected to view these files. dbcheck.exe can check out 80% of the problems related to embedded database. reformatvob VOB embedded database will be exported as text files, or export the file back into a new database for database upgrades and reduce the database size. vob_sidwalk VOB database elements to change the security label, that is, users and groups marked. fix_prot produce or repair. identity / identity.sd file. lsacl shows the safety labeling for a combination of fix_prot VOB can repair the directory and file access control. rmtype remove the type of object in the VOB can be used to reduce the size of the embedded database. rmver remove elements version, can be used to reduce the size of the embedded database. vob_scrubber_params file scrubber to adjust the frequency of operation, so as not to VOB too large, but if the argument is too small, will cause system performance degradation. 5. Conclude that when the VOB problem, you should try to first use the tools mentioned above to locate the problem, determine the problems embedded in the VOB database and storage pool, or the synchronization between the two. Then use the appropriate tools for repairs. Finally a reminder, as a ClearCase administrator should always back up critical data systems. Fifth, the file plays 1. Summary of VOB is the DVD Video OBject acronym, meaning that DVD video object. This is the key documents on DVD video discs, the film contains the actual data. VOB file is actually a basic MPEG-2 data stream, that is, it contains a complex multi-channel MPEG-2 video data stream, audio stream (normally AC3 format code), and subtitle streams. 2. Playback VOB files can have a few vob file player,
chi pink dazzle limited edition, you can use KMplayer, Storm video and so on. Storm Windows Media Player audio and video as a supplement and improvement of storm video system to provide and upgrade the popular audio and video files and streaming support, including Real, QuickTime, MPEG-2, MPEG-4 (DivX/XviD/3ivx, MP4, AVC/H264 ...), AC3/DTS, ratDVD, VP3/6/7, Indeo, XVD, Theora, OGG / OGM, Matroska, APE, FLAC, TTA, AAC, MPC,
Chi dazzle flat iron, Voxware, 3GP/AMR, TTL2, subtitles. With the latest version of Windows Media Player can complete most of the popular audio and video files, streaming media, DVD player, etc. without any other software. Is a very popular VOB file player. KMplayer is also a very powerful media player, media formats and support almost so, of course, include the vob files. 3. Extracted VOB file in DVD disc, is stored in VOB files, which is equivalent to the DAT VCD files that if not encrypted,
chi turbo flat iron, you can use Explorer to copy the VOB files and these can be Some subtitles IFO files directly copied to the hard drive, but these VOB files are very large, generally more than one VOB file of about 1GB. DVD disc in a 4-5 VOB files of this size, which requires a large enough hard disk space. If the file is encrypted, you can not directly copy,
cheap chi straighteners, need some special software to copy, such as DeCSS, SubRip. In the use of DeCSS, if the DVD is not CSS encrypted, although the display when using the DeCSS copy complete, but not copied to the hard drive, so such cases, direct use Explorer to copy these files on it. 3gp mobile phone converter can also be the king of this vob vob conversion tool to convert the MP4 format or 3GP video format. Sixth, import vob file editing method software installation 1. Download and install AviSynth 2.5.5 RC3 Avisynth is a powerful video processing Utility (utility), the use of its Frameserving function can import various file formats PR such as RM / RMVB, swf, vob and so on. 2. Download and install the Premiere avisynth import filter 1.1b This is the Premiere plug-in, install the plug-in aims to make PPRO2.0 to Plugin file IM-Avisynth.prm, select the installation directory plugins PR Adobe Premiere Pro 2.0 Plug-ins en_US. Write [Recommend that you file with the VOB splitter (VOBSplitter 2.6) finished version of the DVD disc in the VOB format video file into small sections and then edit it. ] 2, in the film the same folder (ie D: vob) to create a new Notepad file, write the following control statements: DirectShowSource (vob video files, 25 frames per second (fps). 3, save the name Myvideo, the extension. Txt into. Avs (namely Myvideo.avs). Output video in Premiere to import movies into Myvideo.avs, as usual editing avi, mpg, like video editing work. Finally, after editing out the new video. This, using Premiere software to import vob files, then editing the work has been completed. Seven other: business needs 1. Six Sigma originated VOB (voice of business) is derived from the initial part of enterprises to implement Six Sigma standards. Six Sigma is to eliminate defects in any process of comprehensive standards, initially used for manufacturing and product engineering, and then extended to product design and customer service. (Junior's system is DMAIC - D-Definition, M-measurement, A-analysis, I-improvement and C-control - step by step to eliminate defects. 2. On the VOB
vob format
6sigma repeatedly stressed that the project choice is to pay attention to VOC and VOB, the VOB is the From this vision goals, the decomposition of secondary units in all the short-term and long-term performance goals, followed by gradual decomposition of the unit or individual performance goals. Where the most need to improve it? Is in business development in every step of the bottleneck, from the performance indicators can be seen that those benchmarks or competitors, the worst place. If the business from top to identify such a region, then the lower-level units do not own efforts to be clear direction? Each level in the implementation may conflict, as long as clearly defined strategy of conflict resolution, to be able to do the overall coordination of orderly development. In the specific issues, the use of 6sigma problem solving, or innovative design ideas and a series of tools for making outstanding contributions to high-level goals, such projects must be acclaimed. Business needs so down, at all levels of ability to uplink to be able to protect the enterprise at all levels has always been the limited resources on the most critical position, but this time in a business improvement activities to develop.
