[FFmpeg-devel] [PATCH] tests: add jpg-icc test

From: Niklas Haas Transcoding from an existing PNG file that has an embedded ICC profile. Note that this ICC profile is smaller than 64 kB, so this doesn't test the APP2 chunk re-arranging code at all. Signed-off-by: Niklas Haas --- tests/fate/image.mak | 3 +++ tests/ref/fate/jpg-icc | 42
