New description:

 Summary of the bug:
 I'm trying to create a multi-codec m3u8 playlist with a 1080p hevc track
 and a 720p h264 track, but the result is this:
 #EXTM3U
 #EXT-X-VERSION:6
 #EXT-X-STREAM-INF:BANDWIDTH=8263200,RESOLUTION=1920x960
 stream_0/playlist.m3u8

 #EXT-X-STREAM-
 INF:BANDWIDTH=2411200,RESOLUTION=1280x640,CODECS="avc1.4d401f,mp4a.40.2"
 stream_1/playlist.m3u8

 I already found other topics about this issue, but I've read it has been
 fixed around 2 or 3 years ago... so how come I can't get this command to
 work properly and output the CODECS attribute for the hevc track? I've
 also tried with libx265 but I get the same result.


 How to reproduce:
 {{{
