[FFmpeg-devel] [PATCH v2] fate: add vf_overlay test for main source with alpha channel

[Peter Große]

Signed-off-by: Peter Große <pegro at friiks.de>
---
This depends on patch "lavfi/testsrc2: fix completely transparent alpha."

The test fails without the patch "avfilter/vf_overlay: fix alpha blending when 
main source has an alpha channel".
