HEVC Failing to decode on HDHomeRun Flex 4k #529
Comments
In the tuner setting or globally? The Tuner setting does nothing to the server transcoding pipeline, it is only used to hint the tuner to use its own decoder or not. I think turning off hardware decoder globally could workaround this issue as the software decoder is more robust to streams from livetv where not everything is reliable. |
I turned off global hardware transcoding to test. It actually doesn't get as far with HW transcoding turned off, it just hangs:

Do you have something with faster cpu to tests with? Trying hevc decoding with CPU on N6005 is not fun and it might hang even for normal videos. If it still fails on a fast CPU the I don’t really know what to do if even ffmpeg cannot understand the stream from the tuner. |
@gnattu AMD AMF None Worked fine -> lags a little INTEL QUICKSYNC -> Not working Now used to work before System: i can revert the packages and test the same if need |
If you are not using HDHomeRun Flex 4k you are not having “similar” issue. Also blindly choosing methods won’t help. It looks like you are very unfamiliar with hardware acceleration setup so I suggest you to ask in our forum or the matrix channel for help. |
When trying to decode HEVC (I think without the correct bitstream from this reddit post), ffmpeg fails to start encoding. This is any HEVC ATSC 3.0 Channels using the HDHomeRun Flex 4k by silicon dust (network tuner).
Steps To Reproduce
Expected Behavior
HEVC live streams can be decoded and encoded using ffmpeg.
System (please complete the following information):
Ubuntu 24.04.1 LTS (GNU/Linux 6.8.0-48-generic x86_64)
Server version 10.10.4
Web version 10.10.4
Build version 10.10.4
Hardware Acceleration: QSV
CPU & GPU Model: Intel N6005

FFmpeg Logs
Additional Context
I tried turning off HW acceleration and there was no difference in logs or behavior.
