[FFmpeg-devel] FATE: testing lossless video differently

[Peter B.]

Hi :)

I'm having difficulties implement FFV1 lossless FATE tests in a way that
seems more appropriate.
I'd be grateful for advice how to deal with this:

I'd rather use "framecrc" instead of the "enc_dec" method used in
vodec.mak. Yet, the usage of framecrc in the tests for other lossless
codecs in "lossless-video.mak", only seem to validate decoding of given
source files in the fate-suite samples collection.


I've checked the BASH code of the testing functions (enc_dec(),
framecrc()) in "tests/fate-run.sh".

I was thinking about adding a new function to tests/fate-run.sh that
does something like this:
1) encode-and-convert vsynth*.yuv
2) framecrc the generated output
3) decode the generated output
4) compare framecrc of encoding with framecrc of decoding

What do you think?


Thanks in advance,
Pb
