| * riff: always generate a proper WAVEFORMATEX structure in ff_put_wav_headerJohn Brooks2011-10-148-204/+204
| | | | | | | | | | | | | | | | | | | | | | | | | | | | The cbSize field should be included in all cases, even with PCM where its value is ignored. Fixes encoding PCM audio in Matroska for some players which insist on a full WAVEFORMATEX structure for A_MS/ACM audio. Since fate uses wav files for the audio test a larger number of tests has changed checksums or shifted positions due to the 2 byte longer wave header.

* asf: update seek test referenceMans Rullgard2011-03-173-87/+81
| | | | | | | | | | | This updates the seek test reference to match de11ee9. Before this change, most of the seeks requested positions before the supposed start of the file (the preroll time), resulting in the first packet being returned. With the preroll subtracted, some of these seeks will land within the file and some beyond the end, thus returning a different set of packets. Signed-off-by: Mans Rullgard <mans@mansr.com>
* ac3enc: do not right-shift fixed-point coefficients in the final MDCT stage.Justin2011-03-141-11/+11
| | | | | | | | | 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.
* ac3enc: fix bug in stereo rematrixing decision.Justin Ruggles2011-02-161-10/+20
| | | | | | | The rematrixing strategy reuse flags are not reset between frames, so they need to be initialized for all blocks, not just block 0. Signed-off-by: Mans Rullgard <mans@mansr.com>
* Add stereo rematrixing support to the AC-3 encoders.Justin Ruggles2011-01-081-14/+7
| | | | | | | | This improves the audio quality significantly for stereo source with both the fixed-point and floating-point AC-3 encoders. Update acodec-ac3_fixed and seek-ac3_rm test references. Originally committed as revision 26271 to svn://svn.ffmpeg.org/ffmpeg/trunk
* Change the default dB-per-bit code from 2 to 3.Justin Ruggles2010-12-291-17/+16
| | | | | | | | | | | | 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. Regression test refs updated for acodec-ac3, lavf-rm, and seek-ac3_rm. Originally committed as revision 26144 to svn://svn.ffmpeg.org/ffmpeg/trunk
* Change FIX15() back to clipping to -32767..32767.Justin Ruggles2010-12-211-7/+5
| | | | | | | | This avoids a 16-bit overflow in mdct512() due to a -32768 value in costab. References updated for acodec-ac3, lavf-rm, and seek-ac3_rm tests. Thanks to Måns Rullgård for finding the bug. Originally committed as revision 26071 to svn://svn.ffmpeg.org/ffmpeg/trunk
