Testsuite finished for SVT 576i25 SGI-Material converted to different
colorspaces.
All framemd5 check results are good:

Which RGB colorspaces (except bgr0) are supported by FFv1.3 and should
be checked?
For testing pix_fmts with alpha-channel, I hope to be able to generate
input-test content using FFmpeg, applying some non-empty but bogus alpha
mask.

After these RGB and >8 bit YUV tests, the bitstream itself seems
reliable to be be used for these colorspaces tested.

@Michael:
Except for the multipass tests, which tests are still open from your
point of view, before marking FFv1.3 as non-experimental?

Thank you very much,
