Description

I've followed http://wiki.webmproject.org/adaptive-streaming/instructions-to-do-webm-live-streaming-via-dash tutorial, but altered a little to create chunked VOD webm DASH streaming:

  1. Preparing 2 sec video and audio chunks:
    $ ffmpeg -i http://www.sample-videos.com/video/mp4/720/big_buck_bunny_720p_10mb.mp4 -map 0:0 -c:v libvpx-vp9 -s 640x360 -keyint_min 50 -g 50 -tile-columns 4 -frame-parallel 1 -b:v 3000k -f webm_chunk -header webm_video_360.hdr -chunk_start_index 1 webm_video_360_%d.chk -map 0:1 -c:a libvorbis -b:a 128k -ar 44100 -f webm_chunk -audio_chunk_duration 2000 -header webm_audio_128.hdr -chunk_start_index 1 webm_audio_128_%d.chk

comment:2 Changed 3 years ago by cehoyos

Which software plays the file(s) you created with the first command?

comment:3 Changed 3 years ago by pszemus

I don't know any software that can play chunked content without any manifest file (the first command doesn't generate one) although FFmpeg can handle that after adding "-live 1" to input parameters, but I don't want to do that because it's not a live stream.

comment:4 Changed 3 years ago by pszemus

And then it cannot detect the duration, maybe that's because of the "-live 1" parameter.

comment:5 Changed 3 years ago by cehoyos

Sorry if I misunderstand: Didn't you report that by modifying some available instruction you can generate a file with FFmpeg that FFmpeg isn't able to read? And now you explain that nothing can play the resulting file?

comment:6 follow-up: Changed 3 years ago by pszemus

Let me rephrase my problem: video and audio chunks that I created using the 1st command are valid webm chunks. To support my thesis I can play them concatenated using ffplay:

ffplay -i "concat:webm_video_360.hdr|webm_video_360_1.chk|webm_video_360_2.chk|webm_video_360_3.chk|webm_video_360_4.chk"
Input #0, matroska,webm, from 'concat:webm_video_360.hdr|webm_video_360_1.chk|webm_video_360_2.chk|webm_video_360_3.chk|webm_video_360_4.chk':
  Metadata:

ffplay -i "concat:webm_audio_128.hdr|webm_audio_128_1.chk|webm_audio_128_2.chk|webm_audio_128_3.chk|webm_audio_128_4.chk"
Input #0, matroska,webm, from 'concat:webm_audio_128.hdr|webm_audio_128_1.chk|webm_audio_128_2.chk|webm_audio_128_3.chk|webm_audio_128_4.chk':

  Duration: N/A, start: 0.000000, bitrate: N/A
    Stream #0:0: Audio: vorbis, 44100 Hz, 5.1, fltp (default)

But then I cannot generate DASH manifest for them neither using only header/init video and audio chunks:

ffmpeg -f webm_dash_manifest -i webm_video_360.hdr -f webm_dash_manifest -i webm_audio_128.hdr -c copy -map 0 -map 1 -f webm_dash_manifest -adaptation_sets "id=0,streams=0 id=1,streams=1" -chunk_start_index 1 -chunk_duration_ms 2000 manifest.mpd

Do you at least agree that it should be corrected?

comment:8 in reply to: ↑ 6 Changed 3 years ago by cehoyos

Replying to pszemus:

Let me rephrase my problem: video and audio chunks that I created using the 1st command are valid webm chunks. To support my thesis I can play them concatenated using ffplay:

I don't think FFplay can be used to show that a particular file is "valid".

But then I cannot generate DASH manifest for them neither using only header/init video and audio chunks:

What can create such manifests for these files?

I don't know how to convince you they are valid. I can play any chunk(s) after concatenating with hdr file using ffplay, mpv, vlc...
e.g.

cat webm_video_360.hdr webm_video_360_3.chk | {ffplay -i,mpv,vlc} -

But I cannot generate DASH manifest for them. If it's not a bug then maybe at least a feature request?

ping?

Any comment on that? It's been a month now.
