Hmm, that's problematic - we need to sort that out before we can push this test. It's possible that this is a bug in the mmxext implementation. It's also possible that it is a case where the test is overly strict about something where we legitimately are allowed to deviate a little. (E.g. for cases where we know we have aligned/padded line sizes, it may be acceptable to overwrite the payload area by a couple of bytes.) For failures in mmx tests, it's also possible that the declare_func should be a declare_func_emms instead. We'd need to check exactly what differs in the output. // Martin _______________________________________________ ffmpeg-devel mailing list ffmpeg-devel@ffmpeg.org https://ffmpeg.org/mailman/listinfo/ffmpeg-devel To unsubscribe, visit link above, or email ffmpeg-devel-request@ffmpeg.org with subject "unsubscribe".
