I tried a bunch of files that were encoded with B-frames set to 5, I can’t explain why, but they would not play with the buffer set less than 3xB-frame setting. Unfortunately I don’t know what the B-frame setting was on the 10 files above. Mediainfo doesn’t report B-frame information, and for some reason ffprobe is broken. ---

@enJOyIT Yes, Topic still open. We’re narrowing in on it. Can you please test for me: 1. Any Nvidia 525 driver (I’m using 525.60.13) 2. PMS 1.29.2.6364 Hardware transcoding errors should be gone. I ask this because we’re getting multiple reports of normal transcoding when using PMS 1.29.2.6364. It was discovered last night. We’re trying to run it down and set a “known good” datapoint. > **[plexmediaserver\_1.29.2.6364-6d72b0cf6\_amd64.deb](https://drive.google.com/file/d/11H2PdiTaLc_hFqIG6vzgb5w-1qnvt86T/view?usp=sharing)** > > Google Drive file. ---

I currently have 525.60.11 installed, close enough? When I install this new version do I remove the framebuffer flag? I’ll look at it tonight. ---

@zenon222 I’d try it both ways. There’s no harm. PMS 1.29.2 has no knowledge of it. PMS 1.29.2 should silently remove the flag since it has no knowledge of it. ---

I was testing 1.29.2.6364, my understanding is that code development is still in the works for this bugfix. ---

1.31.0.6654 is a step in the right direction. The problem with this is we’ve not identified the **exact** root cause because everyone’s files, while failing with the same errors, don’t fail for **everyone**. Those cases, where the failures were reproducible by us as well **have** been addressed in 1.31.0.6654 but I doubt this is resolved yet. ( The 1080p input bit rate reduction transcoding problem ) I believe we all saw the most stable operation at 1.29.2.6364 and CUDA version 11.7 (pre 525 drivers) With 1.30.x, AV1 decoding is now included for those with the capability. Whether it’s FFMPEG core, or the transcoder, the updated transcoding with the updated (required) Nvidia drivers, is where we now see failures. Feature wise, there is little difference between 1.29.2 and 1.30.x at this point. The choice is yours whether to upgrade or not. ---

Just want to bump this again. I have HEVC files where HW transcoding fails at anything above 720p. I’m running PMS 1.31.1.6733 with Nvidia 525.89.02 on a GTX 1660 Super. I don’t think this is a driver or hardware issue, because the exact same files can be transcoded to H246/1080p just fine through Jellyfin, which uses ffmpeg ---
