The plain VP6 format is vertically flipped compared to VP6F/VP6A. Support for the plain VP6 format was added in 09d8c0ae (which also introduced support for muxing VP6F properly in general). Signed-off-by:

In these cases, there is no extradata but only the properly set width/height values by the demuxer. This makes sure VP6 in F4V files is cropped properly. This is similar to what is done for H264 for letting the container width/height override what's in the bitstream, since 30f51509. Signed-off-by:

The Mach-O bug was fixed in yasm 0.8.0 and we don't support versions that old anymore. Signed-off-by:

This is in preparation for removing a .rodata kludge which was only required for older YASM versions. The movbe instruction was introduced in 0.8.0, which already had AVX, which was introduced in 0.7.0, and NASM introduced movbe in 2.0.3, which is the same version which introduced AVX support. Also, make the failure message more accurate. Signed-off-by:

Prevents a crash if the misaligned exception mask bit is cleared for some reason. Misaligned SSE functions are only used on AMD Phenom CPUs and the benefit is miniscule. They also require modifying the MXCSR control register and by removing those functions we can get rid of that complexity altogether. Signed-off-by:

The implementation of 25cb0c1a involves lots of spurious labels. The effect of keeping those labels around is making debugging harder. Those labels are meaningless, and complicate the disassembly. Also, gdb can't tell the difference between them and function entry points. This new strip command is irrelevant to any usage of Libav that would have used the old fully stripped version, because the old one was for non-debug use. Signed-off-by:

Now RET checks whether it immediately follows a branch, so the programmer dosen't have to keep track of that condition. REP_RET is still needed manually when it's a branch target, but that's much rarer. The implementation involves lots of spurious labels, but that's OK because we strip them. Signed-off-by:
