Software-update: MKVToolnix 7.7.0

Versie 7.7.0 van MKVToolNix is uitgekomen. MKVToolNix is een verzameling opensourceprogramma's waarmee Matroska-bestanden kunnen worden bekeken, bewerkt en geconverteerd. Zo kunnen geluidssporen en ondertiteling worden toegevoegd, verwijderd of juist als standaard worden ingesteld. Het zijn afzonderlijke commandline-tools, maar er wordt een grafische gebruikersinterface meegeleverd. Versies kunnen worden gedownload voor Windows, een groot aantal Linux-distributies en OS X. In deze release zijn de volgende veranderingen en verbeteringen aangebracht:

Released v7.7.0.

• source code: Fixed the compilation on cygwin.
• documentation: The Dutch, Ukrainian and Chinese (Simplified) manual pages have contained only untranslated English strings since release 7.0.0. This was due to the files holding the translatable strings having being corrupted by a misbehaving tool in the build process. This has been rectified. Fixes #1134,
• mkvmerge: bug fix: Fixed reading all of the private codec data in AVIs from the 'strf' chunk for codecs that don't set biSize to include that data. Fixes #1129.
• mkvextract: bug fix: Fixed writing AVIs with ckSize fields that were too large. Fixes #1128.
• mmg: new feature: added a button »toggle all« that enables or disables all tracks. It at least one track is currently disabled then all tracks are enabled when pressing that button. Otherwise (if all tracks are currently enabled) then they will all be disabled. Implements #1130.
• mmg: new feature: added a new checkbox »reduce to audio core« on the »format-specific options« tab that passes the new --reduce-to-core option to mkvmerge if enabled. Part of the implementation of #1107.
• mkvmerge: bug fix: fixed determining the key frame status in certain AVIs (those whose dwFlags index field has more bits set than just 0x10).
• build system: new feature: added configure options for building statically-linked binaries (--enable-static). Patches by Florent Thiéry. Implements #1119.
• mkvextract: new feature: implemented a mode for extracting cue information.
• mkvinfo (Qt interface): bug fix: added WebM extensions to the known types in the »Open file« dialog.
• mkvextract: bug fix: Fixed writing AVIs with the wrong bit depth for video codecs that don't use 24 bits/pixel. Fixes #1123.
• mkvmerge: bug fix: Fixed recognition of E-AC3 audio tracks in MPEG transport streams if they use the type ID 0xa1 (and the same for DTS tracks stored with type ID 0xa2). Fixes #1126.
• mkvextract: bug fix: Fixed VobSubs being written to the wrong directory if the output file name given by the user didn't have an extension but one of the directories contained a dot. Fixes #1124.
• mkvpropedit, mmg's header editor: bug fix: if updating the file required creating an EBML void for a 130 bytes long gap then the void element created was one byte too short resulting in an invalid file structure. Fixes #1121.
• mkvmerge: bug fix: If the MP4 track headers for MP3 tracks contain invalid values (number of channels is 0 or the sampling rate is 0) then mkvmerge will re-derive these parameters from the MP3 bitstream instead of ignoring that track.
• mkvmerge: bug fix: Matroska reader: track-specific tags weren't copied for tracks for which the pass-through packetizer was used (e.g. those with the codec ID A_MS/ACM) instead of a specialized one.
• mkvmerge: enhancement: The code for determining the time codes of AAC, AC3, DTS, MP3 and TrueHD packets has been completely rewritten. This improves how timecodes are kept if the source container provides them in many cases.
• mkvmerge: removal: AAC: The hack for using the old codec IDs (e.g. A_AAC/MPEG4/LC/SBR) for AAC tracks has been removed. Those codec IDs have been deprecated for nearly ten years. Reading files that use those IDs will stay supported.
• mkvmerge: removal: TrueHD: The hack for merging a sync frame and all following normal frames into a single Matroska packet has been removed as there are no players that can play such merged frames anyway.
• mkvmerge: new feature: Added an option »--reduce-to-core« that tells mkvmerge not to copy HD extensions for DTS tracks. Part of the implementation of #1107.
• mkvmerge: new feature: mkvmerge will now recognize TrueHD tracks inside MPEG transport streams that contain an AC3 core as consisting of two tracks. Instead of always dropping the AC3 part the user can simply select which tracks to keep. Part of the implementation of #1107.
• mkvmerge: new feature: mkvmerge will now recognize TrueHD+AC3 files as consisting of two tracks. Instead of always dropping the AC3 part the user can simply select which tracks to keep. Part of the implementation of #1107.

mkvmerge: enhancement: The code for determining the time codes of AAC, AC3, DTS, MP3 and TrueHD packets has been completely rewritten. This improves how timecodes are kept if the source container provides them in many cases.

Ben benieuwd of dit het "Delay relative to video"-fenomeen oplost, waarin audiotracks (volgens MediaInfo) regelmatig een delay variërend van ca. 9ms tot 85ms (soms ook negatief, bijv -80ms) krijgen ten opzichte van de videotracks waar ze mee gemuxt worden in mkvmerge. Heb erop zitten googelen maar weet nog steeds niet of dit een bug is, of het resultaat van een normale feature, of een onschuldig bij-effect.

Bijna een tiende van een seconde, neem je dat waar?
Ik gelukkig niet, mijn timing is waardeloos

Als het richting de 100ms gaat, kan ik het helaas wel waarnemen, vooral bij lip sync. Maar soms denk ik ook dat ik het me inbeeld . Er valt dus op zich mee te leven en het valt sowieso in mkvmerge te fixen. Ik zou alleen graag willen weten of het een soort bug is of niet...
