The standard syntax requires two destination registers for LDRD/STRD instructions. Some versions of the GNU assembler allow using only one with the second implicit, others are more strict. Signed-off-by:

64-bit CPUs always have SSE available, thus there is no need to compile in the 3dnow functions. This results in smaller binaries.

The yadif mmx optimizations contain the pmaxsw and pmaxub mmxext instructions, causing sigills on CPUs that do not support mmxext.

This completes the conversion of h264dsp to yasm; note that h264 also uses some dsputil functions, most notably qpel. Performance-wise, the yasm-version is ~10 cycles faster (182->172) on x86-64, and ~8 cycles faster (201->193) on x86-32.

These decoders use a special non-MPEG2 IDCT. Call it directly instead of going through dsputil. There is never any reason to use a regular IDCT with these decoders or to use the EA IDCT with other codecs. This also fixes the bizarre situation of eamad and eatqi decoding incorrectly if eatgq is disabled. Signed-off-by:

There is no sense in pulling in this monster struct just for a handful of fields. The code does not call any functions expecting an MpegEncContext. Signed-off-by:

This allows for padding/trimming at the start of stream. By default, no assumption is made about the first frame's expected pts, so no padding or trimming is done.

We match streams by codec id now.

According to its description, it is supposed to be the LCM of all the frame durations. The usability of such a thing is vanishingly small, especially since we cannot determine it with any amount of reliability. Therefore get rid of it after the next bump. Replace it with the average framerate where it makes sense. FATE results for the wtv and xmv demux tests change. In the wtv case this is caused by the file being corrupted (or possibly badly cut) and containing invalid timestamps. This results in lavf estimating the framerate wrong and making up wrong frame durations. In the xmv case the file contains pts jumps, so again the estimated framerate is far from anything sane and lavf again makes up different frame durations. In some other tests lavf starts making up frame durations from different frame.

AVPacket.duration is mostly made up and thus completely useless, this is especially true for video streams. Therefore use dts difference for framerate estimation and the max_analyze_duration check. The asyncts test now needs -analyzeduration, because the default is 5 seconds and the audio stream in the sample appears at ~10 seconds.

Useful in cases where a significant analyzeduration is still needed, while minimizing buffering before output. An example is processing low-latency streams where all media types won't necessarily come in if the analyzeduration is small.

MMX-enabled systems by default use some dsputil functions differing from the C versions. Adding these flags ensures accurate ones are used everywhere. Signed-off-by:
