It seems autovideoconvert invokes mfxvpp to perform the NV12 ->YUY2 conversion, which the J1900 unfortunately doesn't support. Have you tried with the latest driver?

That's bad. GST-MFX doesn't yet have a mechanism to determine the hardware support for colorspace conversion before finalizing the output caps. From Haswell onwards, NV12->YUY2 is supported and I enabled...

Thanks as well for your feedback :) It's fine. I can't just disable YUY2 output format support unless I am sure which hardware doesn't support it. I assume that 3rd...

Also if you do have have the time to test, can HEVC Main 10 decode work on Braswell? You can get some samples here: https://kodi.wiki/view/Samples

Not sure what you mean, but the log message you see is a warning you can safely ignore.

Perhaps a cleaner solution would be to use an environmental variable to set the path of the DRM device instead of this hack.

Maybe LIBVA_DEVICE_PATH could be a good name.

It's not done. Could be added to the code....

You got a typo in your first pipeline with the '\\' in front of '=' in your caps. It should be : ... ! gldownload ! video/x-raw, format=RGBA ! ...

That's strange. Can you do a clean build of gst-mfx with GStreamer 1.14?
