The bug it was working seems to have been fixed. This change causes ffmpeg to use the trim filter to implement the -t option. FATE tests are updated due to the more accurate handling of the last packets.

This makes -t sample-accurate for audio and will allow further simplication in the future. Most of the FATE changes are due to audio now being sample accurate. In some cases a video frame was incorrectly passed with the old code, while its was over the limit.

Some of the FATE changes are due to off-by-one different rounding being used (lrintf vs av_rescale_q). Some fate changes are due to 1 audio frame less being encoded (the new variant seems matching what qatar does and according to ffprobe its closer to the requested duration) the mapchan feature sadly is lost in this commit because it depends on resampling being done in ffmpeg.c which is now moved completely into the av filter layer -async is broken after this commit, this will be fixed in subsequent commits the new filter reconfiguration system is flawed and will drop a frame on each parameter change which is why the nelly moser checksums need updating. Conflicts: ffmpeg.c tests/ref/fate/smjpeg

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.

This makes the AC3 encoder use the shared fixed-point MDCT rather than its own implementation. The checksum changes are due to different rounding in the MDCT. Signed-off-by: Mans Rullgard <mans@mansr.com>

This increases the accuracy of coefficients, leading to improved quality. Rescaling of the coefficients to full 25-bit accuracy is done rather than offsetting the exponent values. This requires coefficient scaling to be done before determining the rematrixing strategy. Also, the rematrixing strategy calculation must use 64-bit math to prevent overflow due to the higher precision coefficients.

This patch changes the exponent difference threshold in the exponent strategy decision function of the AC-3 encoder. I tested lowering in increments of 100. From 1000 down to 500 generally increased in quality with each step, but 400 was generally much worse. Signed-off-by: Mans Rullgard <mans@mansr.com> (cherry picked from commit c3beafa0)

This gives slightly better quality in PEAQ tests. Code 3 gives a dBpb value of 2816 = -132dB (128 psd units = -6dB), which corresponds to 22 bits. Since the exponents have an offset applied, the 16-bit source looks like 24-bit source to the bit allocation routine. So using dBpb code=3 is a closer match to the exponent range.

With this change, the output is checked immediately after each test has run. This means commands like "make regtest-mpeg2" can now be used to run a single test and get meaningful results. By default, make will abort if any test fails. To run all tests regardless, use make -k. Originally committed as revision 21254 to svn://svn.ffmpeg.org/ffmpeg/trunk
