asf: update seek test reference
This updates the seek test reference to match de11ee9. Before thischange, most of the seeks requested positions before the supposedstart of the file (the preroll time), resulting in the first packetbeing returned. With the preroll subtracted, some of these seeks...
ac3enc: do not right-shift fixed-point coefficients in the final MDCT stage.
This increases the accuracy of coefficients, leading to improved quality.Rescaling of the coefficients to full 25-bit accuracy is done rather thanoffsetting the exponent values. This requires coefficient scaling to be done...
ac3enc: fix bug in stereo rematrixing decision.
The rematrixing strategy reuse flags are not reset between frames, so theyneed to be initialized for all blocks, not just block 0.
Signed-off-by: Mans Rullgard <firstname.lastname@example.org>
Add stereo rematrixing support to the AC-3 encoders.This improves the audio quality significantly for stereo source with both thefixed-point and floating-point AC-3 encoders.Update acodec-ac3_fixed and seek-ac3_rm test references.

Change the default dB-per-bit code from 2 to 3.This gives slightly better quality in PEAQ tests.Code 3 gives a dBpb value of 2816 = -132dB (128 psd units = -6dB), whichcorresponds to 22 bits. Since the exponents have an offset applied, the16-bit source looks like 24-bit source to the bit allocation routine....
Change FIX15 back to clipping to -32767..32767.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.

matroskaenc: Mux clusters better
Start them on keyframes when reasonable, and delay writing audio packetsto help ensure that there's audio samples available for the first frame inclusters.

matroskaenc: Write codec time base as default duration for video tracks.
This isn't exactly semantically equivalent, but the field has already beenlong abused to mean this, and writing it helps in determining a decent cfrtime base when transcoding from a mkv where the video codec stores none (VP8)....

oggdec: Determine pts and filepos on a packet basis in read_timestamp
This takes into account whether the granule defines the start or end timesof packets, and sets the correct file offset of the associated page.
