[PATCH 0/1] MR5597: winegstreamer/video_decoder: Make output_plane_align specific to h264.

[Ziqing Hui (＠zhui)]

If we set output align to wmv decoder, it will fail at copy_video_buffer().
The output size will larger than the sample we provided due to alignment.

Would have been nice to have tests but WMV encoding is messy and I couldn't make it work with the sample images we have. They are somehow too small for it to behave correctly on the non-16byte aligned sizes the tests use.
