* mdec: stop preferring the simple IDCT.Ronald S. Bultje2017-06-21
| | | | | | | | | | | | | | This was added in e3e3c82555e2382125195c1ba9f34b5a43299abc, probably as a workaround for the fact that the quant table was not permutated and the IDCT coefficients are, meaning that you'd only get correct reconstruction if the IDCT permutation was an identity matrix, which happens to be the case when you use the simple IDCT. The quant table permutation bug was fixed in 42dd1434bf6a7230e4175c08fcfabc3ba51a0463, meaning this workaround is no longer necessary. In practical terms, before 42dd1434bf6a7230e4175c08fcfabc3ba51a0463, the PSNR between decodes of the fate-mdec using simple (C) or simplemmx IDCTs was 35. After 42dd1434bf6a7230e4175c08fcfabc3ba51a0463, it's 90.

* ffmpeg: remove misleading and incorrect warning messageswm42017-06-20
| | | | | | | | | | | | | | | | | | | | | | It is wrong/incorrect in two aspects: 1. The pixel format is not enough to guarantee that the resulting file will be any more compatible with media players. 2. Media players not supporting higher profiles are not necessarily outdated (in fact this is simply an arrogant statement that libavcodec can handle these particular features). You could add that there are plenty of other ways to produce widely incompatible files with ffmpeg, and these don't show any warnings. What we really want to do here is defaulting to codec profiles that have wide compatibility, such as main/high for h264. Also, if an encoder does not accept certain pixfmts, we should automatically convert them to a pixfmt the encoder can accept. But the existing message certainly is not appropriate. It also works for 2 specific encoders only. Extending it for other cases would result in a lot of special cases, so this is not the right place.

* libavfilter/scale: Populate ow/oh when using 0 as w/hKevin Mark2017-06-19
| | | | | | | | | | | | | | | | | | | | | | The input width and height is known at parse time so there's no reason ow/oh should not be usable when using 0 as the width or height expression. Previously in "scale=0:ow" ow would be set to "0" which works, conveniently, as "scale=0:0" is perfectly valid input but this breaks down when you do something like "scale=0:ow/4" which one could reasonably expect to work as well, but does not as ow is 0 not the real value. This change handles the 0 case for w/h immediately so the ow/oh variables work as expected. Consequently, the rest of the code does not need to handle 0 input. w/h will always be > 0 or < 0. The second explicit (int) cast ensures that ow/oh appear as integers as a user might expect when dealing with pixel dimensions. Signed-off-by: Kevin Mark <kmark937@gmail.com> Signed-off-by: Ronald S.

* doc/filters: Correct scale doc regarding w/h <= 0Kevin Mark2017-06-19
| | | | | | | | | | | | | | | | According to libavfilter/scale.c, if the width and height are both less than or equal to 0 then the input size is used for both dimensions. It does not need to be -1. -1:-1 is the same as 0:0 which is the same as -10:-42, etc. if (w < 0 && h < 0) eval_w = eval_h = 0; The documentation for the zscale filter has also been updated since the behavior is identical.

* fate: use do_md5sum instead of the md5 protocol for most md5 fate testsMarton Balint2017-06-18
| | | | | | | | | | | | | The md5 protocol has no seek support, but some tests use seeks. This changes the fate tests to actually create the output files and calculate the md5 on the written files, which also makes the tests independent of the size of the output buffers and output buffering in general. A new md5pipe fate test method is also introduced to keep the old functionality for tests where using a non-seekable output was intentional, and matroska md5 tests are changed to use that.
