* ac3enc: Add channel coupling support for the fixed-point AC-3 encoder.Justin Ruggles2011-09-05
| | | | Update FATE references accordingly.
* ffmpeg: deprecate loop_input and loop_output optionsAnton Khirnov2011-07-08
| | | | They were replaced by (de)muxer private options.
* lavf/utils: fix ff_interleave_compare_dts corner case.Vitor Sessak2011-05-10
| | | | | | | | | | This should fix behavior introduced by commit 96573c0d7605672d69b42ae1dcf18764ce47c71a. Av_rescale_rnd() is not lossless so if two timestamps are equal after being rescaled they are not always actually identical. This patch use av_compare_ts() to get always a correct result.

* ac3enc: correct the flipped sign in the ac3_fixed encoderJustin Ruggles2011-04-26

* lavf/utils.c: Order packets with identical PTS by stream index.Vitor Sessak2011-04-12
| | | | | | This allows for more reproducible results when using multi-threading. Signed-off-by: Ronald S. Bultje <rsbultje@gmail.com>
* ac3enc: select bandwidth based on bit rate, sample rate, and number ofJustin Ruggles2011-04-03
| | | | | | | full-bandwidth channels. This reduces high-frequency artifacts and improves the quality of the lower frequency audio at low bit rates.
* Add apply_window_int16() to DSPContext with x86-optimized versions and use itJustin Ruggles2011-03-22
| | | | in the ac3_fixed encoder.
* asf: update seek test referenceMans Rullgard2011-03-17
| | | | | | | | | | | 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.Justin2011-03-14
| | | | | | | | | 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 Ruggles2011-02-16
| | | | | | | 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 Ruggles2011-01-08
| | | | | | | | 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 Ruggles2010-12-29
| | | | | | | | | | | | 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 Ruggles2010-12-21
| | | | | | | | 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
* Update the test references for lavf-rm and seek-ac3_rm.Justin Ruggles2010-12-14
| | | | | | The references changed due to r25956. Originally committed as revision 26004 to svn://svn.ffmpeg.org/ffmpeg/trunk
* Add a FLAC parser.Michael Chinen2010-12-07
| | | | | | | | | Seek test reference updated because FLAC seeking now works properly. Fixes roundup issue 1150. Patch by Michael Chinen [mchinen at gmail] Originally committed as revision 25914 to svn://svn.ffmpeg.org/ffmpeg/trunk
* Avoid negative SCR in mpeg ps muxer.Michael Niedermayer2010-10-16

* regtest: add seektest reference files for rgb/yuv in aviMåns Rullgård2010-06-06
| | | | Originally committed as revision 23506 to svn://svn.ffmpeg.org/ffmpeg/trunk
* matroskaenc: Mux clusters betterJames Zern2010-06-04
| | | | | | | | | | Start them on keyframes when reasonable, and delay writing audio packets to help ensure that there's audio samples available for the first frame in clusters. Patch by James Zern <jzern at google> Originally committed as revision 23473 to svn://svn.ffmpeg.org/ffmpeg/trunk
* matroskaenc: Write codec time base as default duration for video tracks.David Conrad2010-05-24
| | | | | | | | This isn't exactly semantically equivalent, but the field has already been long abused to mean this, and writing it helps in determining a decent cfr time base when transcoding from a mkv where the video codec stores none (VP8). Originally committed as revision 23284 to svn://svn.ffmpeg.org/ffmpeg/trunk
* Update regression tests after removing track timecode scale from mkvencDavid Conrad2010-05-22

* use mpeg2 quantization bias for mjpeg.Michael Niedermayer2010-03-15
| | | | | | this seems to improve RD performance. Originally committed as revision 22550 to svn://svn.ffmpeg.org/ffmpeg/trunk
* oggdec: Determine pts and filepos on a packet basis in read_timestampDavid Conrad2010-03-11
| | | | | | | This takes into account whether the granule defines the start or end times of packets, and sets the correct file offset of the associated page. Originally committed as revision 22462 to svn://svn.ffmpeg.org/ffmpeg/trunk
* oggdec: Set data_offset to the right valueDavid Conrad2010-03-11
| | | | | | | Otherwise it gets set automatically to a page midstream and prevents seeking to the first page. Originally committed as revision 22454 to svn://svn.ffmpeg.org/ffmpeg/trunk
* oggdec: Save offset of the page needed to reconstruct the current packetDavid Conrad2010-03-11

* regtest: run seektest on image sequencesMåns Rullgård2010-03-07
| | | | | | | Seeking on image sequences doesn't actually work, so this test isn't very useful until that capability is added. Originally committed as revision 22286 to svn://svn.ffmpeg.org/ffmpeg/trunk
