Summary of the bug: No audio when creating HLS from AVI
How to reproduce:
I'm using `ffmpeg version N-92215-g8baaed7889 built with gcc 7 (Ubuntu
7.3.0-27ubuntu1~18.04)`
The command I used is: `ffmpeg -i dev.avi -f hls out.m3u8`
The input file can be found here: https://signalratio.ddns.net/fileserver
/ffmpeg-files/dev.avi
The output file can be found here: https://signalratio.ddns.net/fileserver
/ffmpeg-files/out.m3u8
Here is a log produced by "-report":
https://signalratio.ddns.net/fileserver/ffmpeg-files/ffmpeg-master.log
The output file appears to have some problem with its audio stream. When
trying to play it using `ffplay out.m3u8` I hear no audio and in the logs
I see:
`[hls,applehttp @ 0x7f518c000b80] Could not find codec parameters for
stream 1 (Audio: aac (LC) ([15][0][0][0] / 0x000F), 0 channels, fltp):
unspecified sample rate`
`Consider increasing the value for the 'analyzeduration' and 'probesize'
options`
Note:
This does not happen using older versions of ffmpeg. I tried using the one
packaged for ubuntu by default: `ffmpeg version 3.4.4-0ubuntu0.18.04.1
built with gcc 7 (Ubuntu 7.3.0-16ubuntu3)`
The command and input file are the same.
The output file can be found here: https://signalratio.ddns.net/fileserver
/ffmpeg-files/out3.m3u8
Here is a log produced by "-report":
https://signalratio.ddns.net/fileserver/ffmpeg-files/ffmpeg-ubuntu.log
This file produced by the old ffmpeg plays fine with both the old and the
new ffplay.
This file produced by the new ffmpeg fails with both the old and the new
ffplay.
