The assembler may fail to place literal pools close enough to instructions referencing them. An explicit .ltorg directive fixes this. Signed-off-by: Mans Rullgard <mans@mansr.com>

This partially reverts acb17302 which would only have needed to change the checksums if channel mixing had been properly avoided. This changes the output file size reference and the seek test reference back to the previous values.

The new incremental parser doesn't always clear prev_pkt, however the packet queue is cleared when seeking. Which leads to a use-after-free. Verified using Valgrind. Signed-off-by: Dale Curtis <dalecurtis@chromium.org> Signed-off-by: Justin Ruggles <justin.ruggles@gmail.com>

Reduces the amount of upfront data required for cluster parsing thus decreasing latency on seek and startup. The change in the seek-lavf_mkv FATE test is due to incremental parsing no longer reading as much data as the old parser and thus not having that additional data to generate index entries based on keyframes. Index entries are added correctly as the file is parsed. All FATE tests pass and Chrome has been using this patch for ~6 months without issue. Currently incremental parsing is not supported for files with SSA tracks since they require merging packets between clusters. In this case the code falls back to non-incremental parsing.

The mpegts demuxer reads 5 KB at startup just for discovering the packet size. Since the default avio buffer size is 32 KB, the seek back to the start will in most cases be within the avio buffer, and will in most cases succeed even if the actual protocol isn't seekable. This makes the demuxer startup faster/with less data when reading data from a non-seekable input, by not skipping the first few KB. If it fails, don't warn if the protocol isn't seekable, making it behave as before in the failure case. Signed-off-by: Martin Storsjö <martin@martin.st>

This removes all references to AVCodecContext.dsp_mask and marks it for eviction at the next version bump. It has been superseded by av_set_cpu_flag_mask() which, unlike this field, works everywhere. Signed-off-by: Mans Rullgard <mans@mansr.com>

This avoids resampling and channel mixing by using a source with the correct channel layout and sample rate.

Avoids resampling and channel mixing. This only tests the behavior with respect to input and output audio rather than also testing changes to the encoder or muxer that do not affect the resulting decoded output.
