Subject: [PATCH 2/7] waylandsink: match drm kernel driver alignment
|
|
|
|
This workaround is needed to render not 128 bytes aligned YUV420
|
|
planar content.
|
|
|
|
For example:
|
|
$> gst-launch-1.0 videotestsrc ! video/x-raw, format=I420 ! waylandsink
|
|
|
|
This workaround may be dropped when switching to DRM modifier
|
|
implementation introduced in GStreamer-1.24.
|
|
|
|

|
Upstream-Status: Pending
