Scaling via VAAPI not possible #655

Open Hoerli1337 opened 10 months ago

Hi! I'm glad to see that scaling is now available. I can now have the stream converted to a suitable resolution. However, this currently only works with the x264 codec. If I use VAAPI, this does not work. The set resolution is apparently ignored.

As an example, I send a 1440p image to Restreamer and it should scale the image down internally from 1440p to 1080p.

With x264 as the codec, everything works without any problems. The specified resolution is also converted there, but this is at the expense of the CPU.

I've got the same Issue here.

Unfortunately, the bug is still there. I would also like to add that the options to rotate the image and flip horizontally / vertically do not work either.
