[FFmpeg-devel] [PATCH 0/2] Fix VC-2 encoder

[Christophe Gisquet]

The encoder was leaving uninitialized data in the padding of slices,
while the specs seem to mandate the use of 0xFF. This is also the case
for the slice prefix, but it seems completely unused.

To validate this, classical vsynth encoding/decoding fate tests for
all supported chroma formats are added. Suggestions for being even
more concise in the target/rules are welcome.

Christophe Gisquet (2):
  vc2enc: prevent random data
  vc2: fate tests
