The encoder names seem to be vastly different and tied to the devices they represent. It may be the new way how to select between devices. Looks like we need a more generic approach to register encoders. I wonder why I'm not seeing this name scheme myself though..

If you can give this branch a try:

I was just about to head to bed, I'll give it a go in ~12 hours :)

Great, I hope the encodes are also working?

Sid127 commented 1 year ago

sorry 😅 H264 seems to be working fine, but selecting HEVC in the recording settings results in a segfault.

Can you make it run with a debug version of the plugin? That way we can at least see on which line the plugin makes it crash. Iirc "it did work in my test" (tm).

But it is also possible that your device exposes more options than mine which runs into an unhandled case.

Also post the output of gst-inspect-1.0 varenderD128h265enc.

Can also be something within Gstreamer itself. The stack trace is quite deep in their territory too..

Sid127 commented 1 year ago

...strange, built with --buildtype=debug, and the HEVC codec works fine now. Still attaching the output of that gst-inspect command gst.log

fzwoch commented 1 year ago

Could be a hint it is still some bug. I will have to test on my end.

I wonder with -buildtype=debugoptimized makes a difference.

fzwoch commented 1 year ago

I can't seem to replicate on my end though :/

fzwoch commented 1 year ago

Merged anyway. The calls tack suggests the crash is happening when instantiating the encoder. This should either succeed or fail. So I assume this is a va plugin error of GStreamer until more info hints otherwise.
