This sets __OUTPUT_FORMAT__ to win64 instead of win32, even though both (through -m amd64) produce 64-bit binary code. Signed-off-by: Ronald S. Bultje <rsbultje@gmail.com>

On Win64, these registers are callee-save, so not saving/restoring them correctly is a violation of ABI and can lead to crashes or corrupt data.

Functions using INIT_MMX may still access XMM registers through direct means (xmm0-15). Therefore, they still need to be marked for clobber so they can be properly saved/restored. Signed-off-by: Ronald S. Bultje <rsbultje@gmail.com>

The spec says the following speaker mapping is default: center front speaker left, right center front speakers, left, right outside front speakers, left surround, right surround rear speakers, front low frequency effects speaker

It was only correct when element ids met very specific criteria.

It is obscure, most likely unused and not bit-exact compared to libavcodec due to a different IDCT transform algorithm.

This fixes crashes in e.g. PNG decoding with SSE2 enabled. In fact, many x86 optimizations for codecs assume that our buffer strides are 16-byte aligned.

Also slightly move around code not allocate a new frame if we won't decode it. This prevents us from putting undecoded frames in frame pointers, which (in mt decoding) other threads will use and wait on as references, causing a deadlock (if we skipped decoding) or a crash (if we didn't initialized next_framep[] at all).

next_dts is used for estimating the dts of the next packet if it's missing. Therefore, it makes no sense to set it from the pts of the last decoded frame. Also it should be estimated from the current packet duration/ticks_per_frame always, not only when a frame was successfully decoded.

It more accurately describes what does this variable store.
-
Anton Khirnov authored
It currently has different meanings at different times (dts of the last read packet/pts of the last decoded frame). Reduce obfuscation by storing pts of the decoded frame in the frame itself.
-
Anton Khirnov authored
It's used to predict dts, not pts.
-
Anton Khirnov authored
Current code compares the desired recording time with InputStream.pts, which has a very unclear meaning. Change the code to use actual timestamps of the frames passed to the encoder. In several tests, one less frame is encoded, which is more correct. In the idroq test one more frame is encoded, which is again more correct. Behavior with stream copy should be unchanged.
-

The actual number (1/1000) will probably require some discussion/tweaking in the future, but should be good enough for now, since the timestamps in AVSubtitle are in this timebase by definition.
-
Anton Khirnov authored
The output is obviously not supposed to contain video (since only -acodec copy is specified), but that only happens because of the way -t handling is implemented currently.

It makes sense in some cases to split up the output packet to save on memory usage (ape frames can be very large), but the current/default size is arbitrary. Allowing the user to configure this gives more flexibility and requires minimal additional code.

This will allow the decoder to return samples for the full packet, and it also makes the decoded buffer pointers aligned.

Calculates based on total file size and wavetaillength from the header. Falls back to multiplying finalframeblocks by 8 instead of 4 so that it will at least be overestimating for 24-bit. Currently it can underestimate the final packet size, leading to decoding errors.

This avoids buffer overread when the last packet size estimate is too small.
