convert not using gpu Debian

[byakuya32 24]

The convert feature will not use the gpu to convert even though it is enable for everything under transcode and full speed conversions are enabled. I have already rebooted. Here are the logs.

Is there an update on this as it worked for a bit now it is not.

@@softworkz is working on this. Thanks for the feedback.

@@byakuya32 - I can't see any issue here. Does hw acceleration work when you do playback (I mean playback that requires transcoding)?

[byakuya32 24]

@softworkz It transcodes with the GPU for playback it just wont convert with the GPU it did for a few files. I'm using the built in convert to convert everything to h.265 it is so slow when it does not use the gpu. It also never user all the cpu resources it has when not using the GPU it has 2 6 core 12  thread cpu's to use and is set to use max threads.

In hardware detection i noticed this:

"Error": {
                    "Number": -1,
                    "Message": "Failed to initialize VA /dev/dri/renderD128. Error -1"

 

I would believe that means that emby doesnt see the right device for gpu hardware acceleration.

Last I remember debian and ubuntu practically ship with support for vaapi hardware acceleration. Do you happen to have vainfo installed?

[byakuya32 24]

I do not have vainfo installed just base debian 10 buster with the gpu drivers

I'm afraid, but the new log you posted (The Witcher S01E01 The End's Beginning.mkv) is not the same file as the one from the log in post #1 (Titanic 1997.mkv). It's not even the same codec.

[softworkz 5066]

Maybe I failed to explain what this is about:

 

• You reported an issue with the conversion feature and posted a log file covering that
  .
• You said that the same transcoding would be working fine in case of playback
  .
• That's why I asked for a logfile showing that situation you mentioned: Playback of that same file that shows that hw acceleration is working in that case

 

The new logfile is showing a totally different file and transcoding case.

@@softworkz Here is is from 4:45 to 4:50 I could not remember the name of the original file that was there but it is all files the seem to not use the gpu in converting to hvec but worked in the past when converting to h.264 with aac audio but playback is fine same with transcode and it used the GPU.

Conversion to HEVC is currently more an experimental than a mature feature. 

I'm afraid, but the only immediate solution is probably to disable the "Nvidia HEVC Encoder" to use sw encoding instead.

[byakuya32 24]

drat it's so slow when it is not using the GPU. It doesn't even use all the CPU that it has available it only uses 60% of mt 2 6 core hyper threaded cpu's. It has to be a bug that is causing this as it converted a few videos to HVEC using my GPU.

@@byakuya32 - If you wouldn't mind installing a beta version, you could try this with the latest beta (4.4.0.8). It might already be fixed there.
