Description
Summary of the bug:
Generating multiple HLS renditions with a master playlist results in defects on variant streams and on the master playlist.
Variant streams, apart from the first entry defined by the -var_stream_map option to HLS have zeroed out duration (EXTINF duration tag is zero) as shown below.
How to reproduce:
I have ran into a problem with the HLS muxer, as shown below.
I want to generate three HLS renditions from a single input file, and
a master playlist pointing to the renditions.
Here's the command line used:
ffmpeg -loglevel debug -threads 4 -filter_complex_threads 4 -vsync 1 -i '/home/lin/Desktop/src/sowdtow.webm' -filter_complex \ "[v:0]split=3[s0][s1][s2]; \ [s0]yadif[v0]; \ [s1]yadif[v1]; \ [s2]scale=w=1280:h=720:force_original_aspect_ratio=decrease:flags=lanczos,yadif[v2]" \ -map "[v0]" -c:v libx264 -pix_fmt yuv420p -preset medium -profile:v main -level 4.1 -b:v 5250k -maxrate:v 6375k -bufsize:v 12600k \ -map "[v1]" -c:v libx264 -pix_fmt yuv420p -preset medium -profile:v main -level 4.1 -b:v 4200k -maxrate:v 4494k -bufsize:v 6300k \ -map "[v2]" -c:v libx264 -pix_fmt yuv420p -preset medium -profile:v main -level 4.1 -b:v 2100k -maxrate:v 2247k -bufsize:v 3150k \ -map a:0 -map a:0 -map a:0 -c:a aac -ar 48000 -ab 256k -af "aresample=async=1:min_hard_comp=0.100000:first_pts=0" \ -f hls \ -var_stream_map "v:0,a:0 v:1,a:1 v:2,a:2" -hls_wrap 24 -hls_time 4 -master_pl_name master.m3u8 \ "/home/lin/Desktop/dest/vs%v/manifest.m3u8"

The command above is supposed to achieve the following goals:
- Split the primary video stream into three, such that separate
outputs governed by the selected encoder (libx264) and separate
filters can be applied, including a re-scale for the third stream.
- Encode the audio stream to three different renditions, and;
- Using the HLS muxer's -var_stream_map , generate appropriate
groupings for the renditions above and a master playlist pointing to
the renditions.
Here's where all goes to hell:
Only the first variable stream map pair (output under
~/Desktop/dest/vs1) has the correct HLS time set in the segments, as
shown below:
less vs0/manifest.m3u8
#EXTM3U #EXT-X-VERSION:3 #EXT-X-TARGETDURATION:4 #EXT-X-MEDIA-SEQUENCE:41 #EXTINF:3.937267, manifest17.ts #EXTINF:4.004000, manifest18.ts #EXTINF:4.070733, manifest19.ts #EXTINF:3.903900, manifest20.ts #EXTINF:2.202200, manifest21.ts #EXT-X-ENDLIST
And now, on to the other broken manifests rendered unplayable:
less vs1/manifest.m3u8
#EXTM3U #EXT-X-VERSION:3 #EXT-X-TARGETDURATION:0 #EXT-X-MEDIA-SEQUENCE:41 #EXTINF:0.000000, manifest17.ts #EXTINF:0.000000, manifest18.ts #EXTINF:0.000000, manifest19.ts #EXTINF:0.000000, manifest20.ts #EXTINF:0.000000, manifest21.ts #EXT-X-ENDLIST
And
vs2/manifest.m3u8:
#EXTM3U #EXT-X-VERSION:3 #EXT-X-TARGETDURATION:0 #EXT-X-MEDIA-SEQUENCE:41 #EXTINF:0.000000, manifest17.ts #EXTINF:0.000000, manifest18.ts #EXTINF:0.000000, manifest19.ts #EXTINF:0.000000, manifest20.ts #EXTINF:0.000000, manifest21.ts #EXT-X-ENDLIST
Note the anomaly in the #EXTINF: period field on vs1 and 2's manifest,
zeroed out, and compare it to the functioning vs0's manifest.
The second anomaly arises in the main manifest:
less master.m3u8
#EXTM3U #EXT-X-VERSION:3 #EXT-X-STREAM-INF:BANDWIDTH=2591600,RESOLUTION=3840x2160,CODECS="avc1.4d4029,mp4a.40.2" vs0/manifest.m3u8 #EXT-X-STREAM-INF:BANDWIDTH=2591600,RESOLUTION=3840x2160,CODECS="avc1.4d4029,mp4a.40.2" vs1/manifest.m3u8 #EXT-X-STREAM-INF:BANDWIDTH=2591600,RESOLUTION=1280x720,CODECS="avc1.4d4029,mp4a.40.2" vs2/manifest.m3u8
Note that according to the master manifest, all three renditions have
the same BANDWIDTH value, despite having separate encoder settings.
Testing with other muxers, such as fifo and tee also result in the same issue.

Notes:
On the tee and fifo muxers, setting the output format to HLS results in the same problem.
Edited to clarify on the last bit.
