#3207: FFmpeg outputs invalid ASS files -------------------------------------+------------------------------------- Reporter: gjdfgh | Type: defect Status: new | Priority: normal Component: | Version: undetermined | unspecified Keywords: | Blocked By: Blocking: | Reproduced by developer: 0 Analyzed by developer: 0 | -------------------------------------+------------------------------------- `ffmpeg -i test.sub out.ass` produces an ASS file with this header: {{{ [Events] Format: Layer, Start, End, Style, Text }}} The "Format:" line, as well as all events following it, is semi-invalid. While it does look like the ASS format is flexible about the headers, and libass actually parses this, it's not accepted by most other ASS readers, such as the (very important) vsfilter. FFmpeg should output standard headers instead. Here's an example of users actually running into this problem: http://www .cccp-project.net/forums/index.php?topic=6826.0 It's possible that libass will drop the header parsing in the future to avoid compatibility problems with real-world scripts. -- Ticket URL: <https://trac.ffmpeg.org/ticket/3207> FFmpeg <http://ffmpeg.org> FFmpeg issue tracker

#2384: ffmpeg detects avi/divx with xsub as broken -------------------------------------+------------------------------------- Reporter: someuser | Type: defect Status: new | Priority: minor Component: | Version: git- undetermined | master Keywords: | Blocked By: Blocking: | Reproduced by developer: 0 Analyzed by developer: 0 | -------------------------------------+------------------------------------- Summary of the bug: When creating an AVI/DivX with XSub subtitles with FFmpeg the result plays fine on supported players but FFmpeg itself complains that the AVI has been generated by broken software. FFmpeg complains this also about AVIAddXSubs generated AVIs. The inputs are ok according to FFmpeg and this should be trivial to reproduce.

#2385(undetermined:new): ffmpeg does not mark xsub language properly

#2385: ffmpeg does not mark xsub language properly -------------------------------------+------------------------------------- Reporter: someuser | Type: Status: new | enhancement Component: | Priority: normal undetermined | Version: git- Keywords: | master Blocking: | Blocked By: Analyzed by developer: 0 | Reproduced by developer: 0 -------------------------------------+------------------------------------- Summary of the bug: When creating AVI/DivX with XSub subtitles using FFmpeg the language for subtitles is not marked properly unless the .idx file happens to contain the needed "alt" tag which might be very hard to discover for casual users. When using AVIAddXSubs or an .idx file with an alt tag with FFmpeg the language of subtitles is recognized properly by player like PS3 with format (below is examples for English and French): alt: Subtitle - en-xx;02 alt: Subtitle - fr-xx;02 I've verified with PS3 that this format works with more than one subtitle streams. It would seem that the optimal solution would be to 1) Use the alt tag from the .idx file if present (=this is what happens today) 2) If the user supplies something like -metadata:s:s:0 language=eng then it should be used (note that the lang codes are 2 chars with XSubs) 3) If there is no alt tag in the .idx file and no metadata options provided in the command line then then add one based on the above format and the language code specified by the id tag in the .idx How to reproduce: If one creates AVI/DivX with XSubs using FFmpeg without the alt tag in the .idx file some player like PS3 present the language of the subtitles as "Other". When using the syntax about PS3 detects the language correctly AND automatically loads the subtitles if a subtitle for language set as default in the player settings is found. Currently, using any metadata command line parameters does not provide the necessary language information being added. -- Ticket URL: <https://ffmpeg.org/trac/ffmpeg/ticket/2385> FFmpeg <http://ffmpeg.org> FFmpeg issue tracker

#3201: A/V desync without -async 1 -------------------------------------+------------------------------------- Reporter: cehoyos | Owner: Type: defect | Status: new Priority: normal | Component: Version: git- | undetermined master | Keywords: Blocked By: | Blocking: Reproduced by developer: 0 | Analyzed by developer: 0 -------------------------------------+------------------------------------- I "fixed" the sample from ticket #3195 with a hex editor to allow testing with MPlayer and older FFmpeg versions. The sample plays fine (no A/V desync) with at least FFplay, MPlayer and vlc, transcoding with FFmpeg leads to a file with severe desync if {{{-async 1}}} was not used. out.avi shows A/V desync: {{{ $ ffmpeg -i detect_aac.mpg -qscale 2 out.avi ffmpeg version N-58799-g5ac5581 Copyright (c) 2000-2013 the FFmpeg developers built on Dec 6 2013 10:16:53 with gcc 4.7 (SUSE Linux) configuration: --enable-gpl libavutil 52. 56.100 / 52. 56.100 libavcodec 55. 45.100 / 55. 45.100 libavformat 55. 22.100 / 55. 22.100 libavdevice 55. 5.102 / 55. 5.102 libavfilter 3. 91.100 / 3. 91.100 libswscale 2. 5.101 / 2. 5.101 libswresample 0. 17.104 / 0. 17.104 libpostproc 52. 3.100 / 52. 3.100 [aac @ 0x19127a0] get_buffer() failed Input #0, mpeg, from 'detect_aac.mpg': Duration: 00:00:31.10, start: 0.000000, bitrate: 19585 kb/s Stream #0:0[0x1e0]: Video: h264 (Main), yuv420p(tv), 1920x1080 [SAR 1:1 DAR 16:9], 30 fps, 30 tbr, 90k tbn, 60 tbc Stream #0:1[0x1c0]: Audio: aac, 44100 Hz, stereo, fltp, 134 kb/s Please use -q:a or -q:v, -qscale is ambiguous Output #0, avi, to 'out.avi': Metadata: ISFT : Lavf55.22.100 Stream #0:0: Video: mpeg4 (FMP4 / 0x34504D46), yuv420p, 1920x1080 [SAR 1:1 DAR 16:9], q=2-31, 200 kb/s, 30 tbn, 30 tbc Stream #0:1: Audio: ac3 ([0] [0][0] / 0x2000), 44100 Hz, stereo, fltp, 192 kb/s Stream mapping: Stream #0:0 -> #0:0 (h264 -> mpeg4) Stream #0:1 -> #0:1 (aac -> ac3) Press [q] to stop, [?] for help [aac @ 0x19127a0] Input buffer exhausted before END element found Error while decoding stream #0:1: Invalid data found when processing input frame= 903 fps=160 q=2.0 Lsize= 103095kB time=00:00:31.13 bitrate=27126.9kbits/s video:102338kB audio:704kB subtitle:0 global headers:0kB muxing overhead 0.051418% }}} Works fine with {{{-async 1}}} {{{ $ ffmpeg -i detect_aac.mpg -async 1 -qscale 2 outasync.avi ffmpeg version N-58799-g5ac5581 Copyright (c) 2000-2013 the FFmpeg developers built on Dec 6 2013 10:16:53 with gcc 4.7 (SUSE Linux) configuration: --enable-gpl libavutil 52. 56.100 / 52. 56.100 libavcodec 55. 45.100 / 55. 45.100 libavformat 55. 22.100 / 55. 22.100 libavdevice 55. 5.102 / 55. 5.102 libavfilter 3. 91.100 / 3. 91.100 libswscale 2. 5.101 / 2. 5.101 libswresample 0. 17.104 / 0. 17.104 libpostproc 52. 3.100 / 52. 3.100 [aac @ 0x21067a0] get_buffer() failed Input #0, mpeg, from 'detect_aac.mpg': Duration: 00:00:31.10, start: 0.000000, bitrate: 19585 kb/s Stream #0:0[0x1e0]: Video: h264 (Main), yuv420p(tv), 1920x1080 [SAR 1:1 DAR 16:9], 30 fps, 30 tbr, 90k tbn, 60 tbc Stream #0:1[0x1c0]: Audio: aac, 44100 Hz, stereo, fltp, 134 kb/s Please use -q:a or -q:v, -qscale is ambiguous -async is forwarded to lavfi similarly to -af aresample=async=1:min_hard_comp=0.100000:first_pts=0.
