[Bug]: gstreamer plugin vapostproc produces tiled output #1820

Closed z0Kng closed 1 month ago

z0Kng commented 3 months ago

Which component impacted?

Video Processing

Is it regression? Good in old configuration?

None

What happened?

Using this pipeline gstreamer

gst-launch-1.0 videotestsrc ! video/x-raw,format=BGRx ! vapostproc ! "video/x-raw(memory:VAMemory),format=NV12" ! vah265lpenc ! h265parse ! matroskamux ! filesink location=test.mkv

produces a tiled image on an intel flex 140. This bug also happens for BGRx, xRGB, xBGR and RGBx as input, while the formats with alpha channel work. Using msdkvpp instead of vapostproc works. Using vaapipostproc and vaapih265enc instead also. Screenshot_20240619_092858

I only could reproduce this bug on an Intel Flex GPU.

I have already opened an issue at gestreamer: https://gitlab.freedesktop.org/gstreamer/gstreamer/-/issues/3634 and was asked to open another one here as it is suspected to be a driver problem.

What's the usage scenario when you are seeing the problem?

Transcode for media delivery

What impacted?

We are currently developing an opensource vdi solution using Flex vGPUs for graphics acceleration and video stream encoding.

I have more information, My setup is:

Furthermore, the following error messages occur when using gst-inspect or using the plugins:
