#1952: FFMPEG not able to copy empty audio stream in wtv -------------------------------------+------------------------------------- Reporter: ramitbhalla | Owner: Type: defect | Status: new Priority: normal | Component: Version: git-master | undetermined Keywords: wtv ac3 | Resolution: Blocking: | Blocked By: Analyzed by developer: 0 | Reproduced by developer: 0 -------------------------------------+------------------------------------- Changes (by cehoyos): * keywords: => wtv ac3 * version: unspecified => git-master Comment: This is not necessarily a bug: FFmpeg cannot copy streams that are detected but not correctly identified (like stream 0:1 in this case). The question is therefore: Is it a bug that the stream is detected (is there actually no stream)? Or is there any software that correctly identifies (plays) the second audio stream? If there is a bug (in the wtv demuxer or the ac3 decoder) it is certainly not mpeg-ts related: You can reproduce the problem with the following command line: $ ffmpeg -i broken_remux.wtv -map 0:2 -acodec copy out.ac3 -- Ticket URL: <https://ffmpeg.org/trac/ffmpeg/ticket/1952#comment:1> FFmpeg <http://ffmpeg.org> FFmpeg issue tracker

The second audio stream contains no data. There are no reliable flags in the WTV file format that indicate when a stream contains no data. {{{ Stream #0:2[0x32]: Audio: ac3, 0 channels, s16 }}} This ticket should be recast as an suggested feature, i.e. give the user a warning when he/she attempts to manipulate a stream that is potentially empty. -- Ticket URL: <https://ffmpeg.org/trac/ffmpeg/ticket/1952#comment:3> FFmpeg <http://ffmpeg.org> FFmpeg issue tracker

Afterall if it doesn't exist it should just show an warning and move on as though it never existed and continue, but it shouldn't fail. We can't control what *Microsoft* does but we can ensure that we don't fail where possible. -- Ticket URL: <https://ffmpeg.org/trac/ffmpeg/ticket/1952#comment:4> FFmpeg <http://ffmpeg.org> FFmpeg issue tracker

It's driving me crazy, I'm not able to convert files because ffmpeg keeps bugging out on Audio Tracks with zero channels. I'm facing the same issue with TS files also - attaching a sample. Very frustrating issue, I'm trying to cut a section of the video and it just bugs out because of this zero channel audio track. There should be some way to continue the stream copy and not FAIL because of a invalid track. This isn't just a microsoft issue, it looks like other media recorders also also creating this zero track audio channel fro some reason. Can FFMPEG throw a warning or put a flag like -ignoreInvalidTracks to skip over these channels? Here's the output {{{ ffmpeg -i zeroAudioChannel.ts -map 0:a -map 0:v -vcodec copy -acodec copy test-out.ts ffmpeg version N-48065-g6375318 Copyright (c) 2000-2012 the FFmpeg developers built on Dec 21 2012 09:06:30 with gcc 4.7.2 (GCC) configuration: --enable-static --arch=x86 --target-os=mingw32 --cross- prefix=/home/rdp/dev/ffmpeg-windows-build-helper s/sandbox/mingw-w64-i686/bin/i686-w64-mingw32- --pkg-config=pkg-config --enable-gpl --enable-libx264 --enable-avisynth - -enable-libxvid --enable-libmp3lame --enable-version3 --enable-zlib --enable-librtmp --enable-libvorbis --enable-libtheo ra --enable-libspeex --enable-libopenjpeg --enable-gnutls --enable-libgsm --enable-libfreetype --enable-fontconfig --ena ble-libass --enable-libutvideo --enable-libopus --disable-w32threads --enable-frei0r --enable-filter=frei0r --enable-lib vo-aacenc --enable-bzlib --enable-libxavs --extra- cflags=-DPTW32_STATIC_LIB --enable-libopencore-amrnb --enable-libopenc ore-amrwb --enable-libvo-amrwbenc --enable-libschroedinger --enable- libbluray --enable-libvpx --enable-runtime-cpudetect libavutil 52. 12.100 / 52. 12.100 libavcodec 54. 81.100 / 54. 81.100 libavformat 54. 49.102 / 54. 49.102 libavdevice 54. 3.102 / 54. 3.102 libavfilter 3. 29.100 / 3. 29.100 libswscale 2. 1.103 / 2. 1.103 libswresample 0. 17.102 / 0. 17.102 libpostproc 52. 2.100 / 52. 2.100 [mpegts @ 01e1c920] PES packet size mismatch Last message repeated 1 times [mpeg2video @ 01e1d0e0] mpeg_decode_postinit() failure Last message repeated 2 times [mp1 @ 02ccace0] Header missing [mpeg2video @ 01e1d0e0] mpeg_decode_postinit() failure Last message repeated 3 times [mp1 @ 02ccace0] Header missing [mpeg2video @ 01e1d0e0] mpeg_decode_postinit() failure Last message repeated 3 times [mp1 @ 02ccace0] Header missing [mpeg2video @ 01e1d0e0] mpeg_decode_postinit() failure Last message repeated 2 times [mp1 @ 02ccace0] Header missing Last message repeated 3 times [mpegts @ 01e1c920] Could not find codec parameters for stream 3 (Unknown: none (TVG1 / 0x31475654)): unknown codec Consider increasing the value for the 'analyzeduration' and 'probesize' options [mpegts @ 01e1c920] decoding for stream 4 failed [mpegts @ 01e1c920] Could not find codec parameters for stream 4 (Audio: mp1 ([6][0][0][0] / 0x0006), 0 channels, s16p): unspecified frame size Consider increasing the value for the 'analyzeduration' and 'probesize' options [NULL @ 02cca4e0] start time is not set in estimate_timings_from_pts [NULL @ 02ccace0] start time is not set in estimate_timings_from_pts [mpegts @ 01e1c920] PES packet size mismatch Input #0, mpegts, from 'zeroAudioChannel.ts': Duration: 00:00:01.26, start: 93213.317522, bitrate: 13338 kb/s Program 1 Stream #0:0[0x31]: Video: mpeg2video (Main) ([2][0][0][0] / 0x0002), yuv420p, 1920x1080 [SAR 1:1 DAR 16:9], 29.97 fp s, 29.97 tbr, 90k tbn, 59.94 tbc Stream #0:1[0x33](eng): Audio: ac3 (AC-3 / 0x332D4341), 48000 Hz, 5.1(side), fltp, 384 kb/s Stream #0:2[0x34](eng): Audio: ac3 (AC-3 / 0x332D4341), 48000 Hz, stereo, fltp, 192 kb/s Stream #0:3[0x111]: Unknown: none (TVG1 / 0x31475654) Stream #0:4[0x110]: Audio: mp1 ([6][0][0][0] / 0x0006), 0 channels, s16p [mpegts @ 0398e020] sample rate not set Output #0, mpegts, to 'test-out.ts': Stream #0:0(eng): Audio: ac3 (AC-3 / 0x332D4341), 48000 Hz, 5.1(side), 384 kb/s Stream #0:1(eng): Audio: ac3 (AC-3 / 0x332D4341), 48000 Hz, stereo, 192 kb/s Stream #0:2: Audio: mp1 ([6][0][0][0] / 0x0006), 0 channels Stream #0:3: Video: mpeg2video ([2][0][0][0] / 0x0002), yuv420p, 1920x1080 [SAR 1:1 DAR 16:9], q=2-31, 29.97 fps, 90 k tbn, 29.97 tbc Stream mapping: Stream #0:1 -> #0:0 (copy) Stream #0:2 -> #0:1 (copy) Stream #0:4 -> #0:2 (copy) Stream #0:0 -> #0:3 (copy) Could not write header for output file #0 (incorrect codec parameters ?): Invalid argument }}} -- Ticket URL: <https://ffmpeg.org/trac/ffmpeg/ticket/1952#comment:5> FFmpeg <http://ffmpeg.org> FFmpeg issue tracker

In your workflow, I suggest you use ffprobe to detect the presence of potientially empty streams, and filter them out using -map. -- Ticket URL: <https://trac.ffmpeg.org/ticket/1952#comment:7> FFmpeg <http://ffmpeg.org> FFmpeg issue tracker
