Description

Summary of the bug:
Since commit 6f69f7a8bf6a0d013985578df2ef42ee6b1c7994 it is not longer possible to convert a live RTMP stream to live MPEG-Dash stream.
By the new commit there are new warnings regarding audio and video stream discovery ("audio stream discovered after head already parsed"

How to reproduce:

% ffmpeg -y -f flv  -i rtmp://184.72.239.149/vod/BigBuckBunny_115k.mov -map 0:0 -c:v libvpx-vp9 -frame-parallel 1 -threads 8 -b:v 8192k -f webm_chunk -header /tmp/video/glass_7673159932128379.hdr -chunk_start_index 1 /tmp/video/glass_7673159932128379_%d.chk -map 0:1 -c:a libvorbis -b:a 128k -ar 44100 -f webm_chunk -audio_chunk_duration 2000 -header /tmp/video/glass_2497349482377957.hdr -chunk_start_index 1 /tmp/video/glass_2497349482377957_%d.chk

  • Keywords webm_chunk regression added; flv rtmp mpeg-dash removed
  • Resolution set to invalid
  • Status changed from new to closed
Stream #0:0: Audio: aac (LC), 12000 Hz, stereo, fltp
Stream #0:1: Video: h264 (Constrained Baseline), yuv420p(progressive), 240x160, 24 fps, 24 tbr, 1k tbn, 48 tbc

Since input stream 0:0 is audio and input stream 0:1 is video, you cannot use -map 0:0 -c:v libvpx-vp9 and -map 0:1 -c:a libvorbis.
Use -map 0:v:0 and -map 0:a:0.

Thank you very much! I don't know why I hadn't seen that...
