Hardware HDR tonemapping still broken on 1.31.0.6654

Plex Media Server
,

I just found a one of the known issues with transcoding.

Specifically –

  1. With Nvidia 525.60.13 (more than new enough)

  2. PMS 1.31.3.6819-2ef591a4c

  3. Start PMS

  4. Allow PMS to settle (inotify table to populate)

  5. Start playback of 2160p HDR in Plex/web ( @ original quality )
    – PMS probes Nvidia P2200 to determine if can transcode.
    – Test passes
    – PMS / Transcoder launch playback session flawlessly

  6. Took date;nidia-smi console log @ server to backup PMS logs

  7. Wait 20 seconds

  8. Change resolution to 1080p - 20 Mbps

  9. Take another ‘date ; nividia-smi’ snapsnot
    – caught transcoder exiting and PMS probing (as it should) in preparation for resolution change

  10. Plex/web shows no video

  11. another ‘date; nvidia-smi’ snapshot shows no transcoder.

  12. Stopped playback in Plex/web

  13. Downloaded logs

Recreation of frequent complaint FINALLY captured.
Submitted to Engineering wtih Logs and Console session ‘date;nvidia-smi’ info.

We got this :smiling_imp:
