#1796(undetermined:new): Unable to extract PCM audio track from AVI file

#1796: Unable to extract PCM audio track from AVI file -------------------------------------+------------------------------------- Reporter: tom_bogle | Type: defect Status: new | Priority: normal Component: | Version: undetermined | unspecified Keywords: | Blocked By: Blocking: | Reproduced by developer: 0 Analyzed by developer: 0 | -------------------------------------+------------------------------------- Summary of the bug: I have an AVI-wrapped dvvideo file with a single pcm_s16le audio track. The video plays fine (although there is a funny noise at the start that might indicate some kind of corruption or encoding problem). I am able to extract the audio using MPlayer, and ffmpeg can successfully produce a lower-quality avi file and extract the audio as mp3. I am able to run ffmpeg a second time to get a WAV file from either of these. However, if I simply try to extract the audio track directly into a WAV file from the original AVI file, all I get is 0.03 seconds of noise. There is no error message, so the software I'm writing that is running ffmpeg and monitoring the output can't tell anything went wrong. How to reproduce: {{{ % ffmpeg -i TruncatedPCMAudio.avi -vn -acodec copy temp.wav - OR - % ffmpeg -i TruncatedPCMAudio.avi -vn -acodec pcm_s16le temp.wav ffmpeg version N-40126-ga4b58fd built on Apr 26 2012 03:29:50 with gcc 4.6.3 }}} ffmpeg -v 9 -loglevel 99 -i TruncatedPCMAudio.avi ffmpeg version N-40126-ga4b58fd Copyright (c) 2000-2012 the FFmpeg developers built on Apr 26 2012 03:29:50 with gcc 4.6.3 configuration: --enable-gpl --enable-version3 --disable-w32threads --enable-ru ntime-cpudetect --enable-avisynth --enable-bzlib --enable-frei0r --enable- libass --enable-libcelt --enable-libopencore-amrnb --enable-libopencore-amrwb --enable -libfreetype --enable-libgsm --enable-libmp3lame --enable-libnut --enable- libope njpeg --enable-librtmp --enable-libschroedinger --enable-libspeex --enable-libth eora --enable-libutvideo --enable-libvo-aacenc --enable-libvo-amrwbenc --enable- libvorbis --enable-libvpx --enable-libx264 --enable-libxavs --enable- libxvid --e nable-zlib libavutil 51. 47.100 / 51. 47.100 libavcodec 54. 15.100 / 54. 15.100 libavformat 54. 3.100 / 54. 3.100 libavdevice 53. 4.100 / 53. 4.100 libavfilter 2. 72.100 / 2. 72.100 libswscale 2. 1.100 / 2. 1.100 libswresample 0. 11.100 / 0. 11.100 libpostproc 52. 0.100 / 52. 0.100 [avi @ 01d3c020] Format avi probed with size=2048 and score=100 [AVI demuxer @ 01d3c680] use odml:1 [avi @ 01d3c020] File position before avformat_find_stream_info() is 32768 [avi @ 01d3c020] All info found [avi @ 01d3c020] File position after avformat_find_stream_info() is 185032 Input #0, avi, from 'TruncatedPCMAudio.avi': Duration: 00:03:52.46, start: 0.000000, bitrate: 28855 kb/s Stream #0:0, 1, 1001/30000: Video: dvvideo, yuv411p, 720x480, 1001/30000, 28 771 kb/s, SAR 8:9 DAR 4:3, 29.97 tbr, 29.97 tbn, 29.97 tbc Stream #0:1, 1, 1/30000: Audio: pcm_s16le, 48000 Hz, 2 channels, s16, 1536 k b/s At least one output file must be specified -- Ticket URL: <https://ffmpeg.org/trac/ffmpeg/ticket/1796> FFmpeg <http://ffmpeg.org> FFmpeg issue tracker

#500(undetermined:new): Seemingly inconsistent AVIndexEntry timestamps for movs starting with B-Frames

#500: Seemingly inconsistent AVIndexEntry timestamps for movs starting with B-Frames -------------------------------------+------------------------------------- Reporter: rmk | Type: defect Status: new | Priority: normal Component: | Version: undetermined | unspecified Keywords: | Blocked By: Blocking: | Reproduced by developer: 0 Analyzed by developer: 0 | -------------------------------------+------------------------------------- A while ago I asked on the ml regarding the semantics of the undocumented fields of AVIndexEntry defined in avformat.h (http://www.mail-archive.com /libav-user(a)ffmpeg.org/msg00535.html) I didn't get an answer so I still do not know what the correct behaviour is but I have observed things that at least appear inconsistent. I have two examples of MPEG-2 files in a mov container which both start with the sequence BBI (presentation order). One is the file that is attached to issue #479 that has the following properties: Mesht0456_01_cut.MP4 AVStream.time_base = 1/30000 AVStream.start_time = 3003 (0.1001s) start frame order = BBI PTS of first I-Frame = 3003 PTS of first frame (B) = 0 first I-frame AVIndexEntry.timestamp = 0 Then another one (uploaded to http://www.datafilehost.com/download- 27d635cc.html since I do not have a smaller sample): xdcam_hd422_1080p24.mov AVStream.time_base = 1/2400 AVStream.start_time = 200 (0.08333333333333334s) start frame order = BBI PTS of first I-Frame = 200 PTS of first frame (B) = 0 first I-frame AVIndexEntry.timestamp = -100 (-0.416666666666667s) The first sample looks like AVIndexEntry.timestamp is set with the stream's start_time subtracted from the respective frame's PTS. This also works for all following index entries. However, this does not work for the second example. I have no idea if this is related to issue #479. All I'm trying to do is use the index (if it is there) to find out the PTSs of keyframes and I thought that was OK to do via AVIndexEntry. So either I am abusing the API and it would help to document this so others don't run into this or one of the files is broken or it is indeed a bug. In any case, just a short, unambiguous sentence of documentation for each AVIndexEntry field by someone who knows the semantics would help libav API users a great deal to use this and to help improve the seeking functionality of ffmpeg be it only by providing bug reports with samples. One more observation is that in both cases the timestamp of the index entry corresponding to the first I frame matches the DTS of the packet containing the I-Frame. Is that the semantics of AVIndexEntry.timestamp? In that case how would one derive the PTS of the I-frame from the index entry? Any insight/help would be greatly appreciated. -- Ticket URL: <https://ffmpeg.org/trac/ffmpeg/ticket/500> FFmpeg <http://ffmpeg.org> FFmpeg issue tracker

#1616(undetermined:new): bad seek in WMV2 file

#1616: bad seek in WMV2 file -------------------------------------+------------------------------------- Reporter: DonMoir | Type: defect Status: new | Priority: normal Component: | Version: undetermined | unspecified Keywords: | Blocked By: Blocking: | Reproduced by developer: 0 Analyzed by developer: 0 | -------------------------------------+------------------------------------- Sample file: http://sms.pangolin.com/temp/bad_seek_wmv2.wmv (3 mb) If you do ffplay -ss 7 bad_seek_wmv2.wmv it works correctly. But ffplay -ss 8 bad_seek_wmv2.wmv will fail with gray frame. For my app, I see corruption and not gray. VLC has a bit of a problem with it but not as bad. WMP gets it perfect. With the following you will get a gray frame and a warning about first frame is not keyframe. The first frame is a keyframe but maybe not the one it seeked to. ffplay -ss 8 CreaToon3.wmv ffplay version N-43206-gf857465 Copyright (c) 2003-2012 the FFmpeg developers built on Aug 4 2012 16:12:33 with gcc 4.7.1 (GCC) configuration: --disable-static --enable-shared --enable-gpl --enable- version3 --disable-w32threads --enable-runtime-cpudetect --enable-avisynth --enable-bzlib --enable-frei0r --enable-libass --enable-libcelt --enable-libopencore- amrnb --enable-libopencore-amrwb --enable-libfreetype --enable-libgsm --enable- libmp3lame --enable-libnut --enable-libopenjpeg --enable-librtmp --enable- libschroedinger --enable-libspeex --enable-libtheora --enable-libutvideo --enable-libvo- aacenc --enable-libvo-amrwbenc --enable-libvorbis --enable-libvpx --enable- libx264 --enable-libxavs --enable-libxvid --enable-zlib libavutil 51. 66.100 / 51. 66.100 libavcodec 54. 49.100 / 54. 49.100 libavformat 54. 22.100 / 54. 22.100 libavdevice 54. 2.100 / 54. 2.100 libavfilter 3. 5.102 / 3. 5.102 libswscale 2. 1.100 / 2. 1.100 libswresample 0. 15.100 / 0. 15.100 libpostproc 52. 0.100 / 52. 0.100 Input #0, asf, from 'CreaToon3.wmv': Metadata: title : CreaToon 3 artist : ANIMANTE BALEARES S.L. copyright : ANIMANTE BALEARES S.L. 2004 WMFSDKVersion : 9.00.00.2980 WMFSDKNeeded : 0.0.0.0000 IsVBR : 0 Duration: 00:00:42.23, start: 0.000000, bitrate: 664 kb/s Stream #0:0(spa): Audio: wmav2 (a[1][0][0] / 0x0161), 44100 Hz, 1 channels, s16, 20 kb/s Stream #0:1(spa): Video: wmv2 (WMV2 / 0x32564D57), yuv420p, 640x480, 671 kb/ s, 25 tbr, 1k tbn, 1k tbc [asf @ 012a04a0] ignoring invalid packet_obj_size (15 116 116 310) [asf @ 012a04a0] freeing incomplete packet size 310, new 1580 1344327525.2[wmv2 @ 012a7060] 2 warning: '''first frame is no keyframe''' Frame changed from size:0x0 to size:640x480q= 0B f=0/0 29.51 A-V: 0.186 fd= 163 aq= 5KB vq= 83KB sq= 0B f=0/0 -- Ticket URL: <https://ffmpeg.org/trac/ffmpeg/ticket/1616> FFmpeg <http://ffmpeg.org> FFmpeg issue tracker

#1823(FFmpeg:new): Allow output file for -report option to be specified.

#1823: Allow output file for -report option to be specified. ---------------------------------------+-------------------------------- Reporter: dericed | Owner: Type: enhancement | Status: new Priority: normal | Component: FFmpeg Version: git-master | Keywords: report Blocked By: | Blocking: Reproduced by developer: 0 | Analyzed by developer: 0 ---------------------------------------+-------------------------------- I find the -report option very useful and run a process that converts many incoming videos and stores the output of the -report option in case any later assessment is needed. Currently in order to file the report with the video I have to first find the report (either by searching the present working directory or grepping the ffmpeg output) and then move it to the place where I want to store it. There isn't really a way to predict what the output report filename will be until after the ffmpeg command has started. I propose implementing an option to specify the filename or directory of the report. Note: I realize that I could simply redirect and sdterr and sdtout to a file, but the output of the -report option additionally carries additional contextual data such as the exact command line and starting date which I'd like to store as well. -- Ticket URL: <https://ffmpeg.org/trac/ffmpeg/ticket/1823> FFmpeg <http://ffmpeg.org> FFmpeg issue tracker

Unfortunately, I had switched to linux lately, so I don't have Adobe Illustrator installed anymore and I don't know of any decent linux replacement for it, so I guees I'll just have to lay out the idea here, for someone who has got it installed. The idea is simple. To create a zig-zag logo to look like a film strip, like these examples: [[Image(http://i48.tinypic.com/154cdhx.jpg)]] [[Image(http://i46.tinypic.com/10fpao6.jpg)]] The idea is not very difficult to implement and here is the simple tutorial how to do it: http://vector.tutsplus.com/tutorials/illustration /from-curve-to-filmstrip-in-adobe-illustrator/ Since it's not that difficult to create it and it looks really cool, I thought I should suggest it. If noone, who is on Winblows, is interested to create it, I'll see to make it myself when I manage to install a VM and Illustrator :) -- Ticket URL: <https://ffmpeg.org/trac/ffmpeg/ticket/1424> FFmpeg <http://ffmpeg.org> FFmpeg issue tracker

#1883(undetermined:new): ASF/WMV Source Aspect Ratio (X/Y) Reversed

#1883: ASF/WMV Source Aspect Ratio (X/Y) Reversed -------------------------------------+------------------------------------- Reporter: starkline | Type: defect Status: new | Priority: normal Component: | Version: undetermined | unspecified Keywords: SAR DAR | Blocked By: Aspect Ratio | Reproduced by developer: 0 Blocking: | Analyzed by developer: 0 | -------------------------------------+------------------------------------- I've noticed this bug only when using ffplay/ffmpeg to decode WMV3 video. I believe ffmpeg is reversing the X and Y values for SAR or PAR, resulting in the wrong DAR. Regression introduced at ffmpeg-20120914-git-8bdba0b. Earlier builds handle DAR/SAR properly. To reproduce find an ASF that has a pixel aspect ratio of, for instance, 4x3, but which requires a display aspect ratio of 16x9 to view properly. If the source aspect ratio is set to 4x3, then the DAR would display correctly at 16x9. However, under current build the DAR is getting set to 1:1. -- Ticket URL: <https://ffmpeg.org/trac/ffmpeg/ticket/1883> FFmpeg <http://ffmpeg.org> FFmpeg issue tracker

It would be really cool, if ffmpeg could support this new standard - as it is already possible to show chapters in MP4/M4A files. This is especially interesting for podcaster, audiobooks, lecture recordings, etc. and with the new opus format! Furthermore it should be quite easy to implement.
