hlsenc muxer in fmp4 mode creates broken init.mp4 with ac3 surround sound input

Description

Given a sample file with a 5.1 ac3 track:

$ curl -o sample.mpg tmm1.s3.amazonaws.com/h264.ts
$ ffprobe sample.mpg
ffprobe version 3.4 Copyright (c) 2007-2017 the FFmpeg developers
Input #0, mpegts, from 'sample.mpg':
  Duration: 00:00:21.54, start: 86589.358267, bitrate: 4956 kb/s
  Program 1256
    Stream #0:0[0xa01]: Video: h264 (High) ([27][0][0][0] / 0x001B), yuv420p(tv, bt709, top first), 1920x1080 [SAR 1:1 DAR 16:9], Closed Captions, 29.97 fps, 29.97 tbr, 90k tbn, 59.94 tbc
    Stream #0:1[0xa02]: Audio: ac3 ([129][0][0][0] / 0x0081), 48000 Hz, 5.1(side), fltp, 384 kb/s

Using the hls muxer to create a fmp4 HLS stream appears to work:

$ ffmpeg -i sample.mpg -c copy -hls_segment_type fmp4 stream.m3u8
Output #0, hls, to 'stream.m3u8':
  Metadata:
    encoder         : Lavf57.83.100
    Stream #0:0: Video: h264 (High) ([27][0][0][0] / 0x001B), yuv420p(tv, bt709, top first), 1920x1080 [SAR 1:1 DAR 16:9], q=2-31, 29.97 fps, 29.97 tbr, 30k tbn, 29.97 tbc
    Stream #0:1: Audio: ac3 ([129][0][0][0] / 0x0081), 48000 Hz, 5.1(side), fltp, 384 kb/s
Stream mapping:
  Stream #0:0 -> #0:0 (copy)
  Stream #0:1 -> #0:1 (copy)

However, the generated init.mp4 is marked as having only two channels, which causes the stream.m3u8 to be unplayable in Safari.

$ ffmpeg -i init.mp4
Input #0, mov,mp4,m4a,3gp,3g2,mj2, from 'init.mp4':
  Metadata:
    major_brand     : iso5
    minor_version   : 512
    compatible_brands: iso6mp41
    encoder         : Lavf57.83.100
  Duration: N/A, bitrate: N/A
    Stream #0:0(und): Video: h264 (avc1 / 0x31637661), none, 1920x1080, SAR 1:1 DAR 16:9, 30k tbr, 30k tbn, 60k tbc (default)
    Stream #0:1(und): Audio: ac3 (ac-3 / 0x332D6361), 48000 Hz, stereo, fltp (default)

To make this a valid ticket, please test current FFmpeg git head and provide your ffmpeg command line together with the complete, uncut console output, ffprobe output is unnecessary.

Does playback with Safari (or QT) work if tho remux the input file to mov or fmp4 (without hls)?

comment:2 Changed 2 weeks ago by tmm1

Yes, it works fine when remuxing into mp4 directly:

$ ffmpeg -i sample.mpg -c copy -y test.mp4
$ ffmpeg -i test.mp4
...
    Stream #0:1(und): Audio: ac3 (ac-3 / 0x332D6361), 48000 Hz, 5.1(side), fltp, 384 kb/s (default)
..

Huh. I'm not sure about that DASH error. It seems like a different bug.

For example, here is another command which works with DASH:

$ ffmpeg -i sample.mpg -c:v libx264 -c:a ac3 -f dash -use_timeline 1 stream.mpd

And same variation with HLS:

$ ffmpeg -i sample.mpg -c:v libx264 -c:a ac3 -hls_segment_type fmp4 stream.m3u8

The init.mp4 generated by the HLS muxer is broken. But the init-stream1.m4s generated by DASH is correct.

$ ffmpeg -i init.mp4
  Stream #0:1(und): Audio: ac3 (ac-3 / 0x332D6361), 48000 Hz, stereo, fltp (default)

$ ffmpeg -i init-stream1.m4s
  Stream #0:0(und): Audio: ac3 (ac-3 / 0x332D6361), 48000 Hz, 5.1(side), fltp (default)
