VLC Player shows broken HLS stream with 4k HDR10 mkv
8 avril 2023, par goodkid38I am trying to convert a 4k mkv to an HLS stream but I am not having any luck. I have tried a few ffmpeg commands to try and fix the issue but none have worked. Here are the commands I have tried.


- 

- Basic copy command :




ffmpeg -i "video.mkv" -c copy -f hls "plexTemp/out.m3u8"


- 

- Command used to see if it was an HDR color issue :




ffmpeg -i "video.mkv" -c copy -pix_fmt yuv420p10le -f hls "plexTemp/out.m3u8"

3. Command used to revert to 8 bit color :

ffmpeg -i "video.mkv" -c copy -pix_fmt yuv420p -f hls "plexTemp/out.m3u8"


- 

- I tried removing extra streams and just focusing on audio and video :




ffmpeg -i "out.mkv" -map 0:v:0 -map 0:a:1 -c copy -pix_fmt yuv420p10le -f hls "plexTemp/out.m3u8"


I also saw these warnings when running each command.
Stream HEVC is not hvc1, you should use tag:v hvc1 to set it.

And this

[matroska,webm @ 000001d7921803c0] Stream #12: not enough frames to estimate rate; consider increasing probesize
[matroska,webm @ 000001d7921803c0] Could not find codec parameters for stream 6 (Subtitle: hdmv_pgs_subtitle (pgssub)): unspecified size
Consider increasing the value for the 'analyzeduration' (0) and 'probesize' (5000000) options
[matroska,webm @ 000001d7921803c0] Could not find codec parameters for stream 7 (Subtitle: hdmv_pgs_subtitle (pgssub)): unspecified size
Consider increasing the value for the 'analyzeduration' (0) and 'probesize' (5000000) options

Consider increasing the value for the 'analyzeduration' (0) and 'probesize' (5000000) options
[matroska,webm @ 000001d7921803c0] Could not find codec parameters for stream 9 (Subtitle: hdmv_pgs_subtitle (pgssub)): unspecified size
Consider increasing the value for the 'analyzeduration' (0) and 'probesize' (5000000) options
[matroska,webm @ 000001d7921803c0] Could not find codec parameters for stream 10 (Subtitle: hdmv_pgs_subtitle (pgssub)): unspecified size
Consider increasing the value for the 'analyzeduration' (0) and 'probesize' (5000000) options
[matroska,webm @ 000001d7921803c0] Could not find codec parameters for stream 11 (Subtitle: hdmv_pgs_subtitle (pgssub)): unspecified size
Consider increasing the value for the 'analyzeduration' (0) and 'probesize' (5000000) options



So I tried increasing the
analyzeduration
andprobesize
and adding the tag like so :
ffmpeg -analyzeduration 10000000 -probesize 10000000 -i "out.mkv" -c copy -tag:v hvc1 -f hls "plexTemp/out.m3u8"


To no avail. Here is what the output looks like on VLC. It's mostly black with a few lines of color that randomly change.


On my TV I see this :




One thing I see that stands out in ffmpegs output is this :


[hls @ 00000207239a9ec0] Opening 'plexTemp/out0.ts' for writing7 bitrate= -0.0kbits/s speed=N/A
[hls @ 00000207239a9ec0] Opening 'plexTemp/out.m3u8.tmp' for writing
