| | | | | | | If this is wanted iam not against it but it must be designed to work with all cases like slice threads, and a single growing buffer does not work very well with slices. Signed-off-by: Michael Niedermayer <michael@niedermayer.cc>

* vaapi_encode: Add VP8 supportMark Thompson2017-02-08
| | | | | | Fixes ticket #6116. (cherry picked from commit ca62236a89f47bd871eaf69d8d9e837c93c55a6c)
* vaapi_encode: Pass framerate parameters to driverMark Thompson2017-02-08
| | | | | | | | | Only do this when building for a recent VAAPI version - initial driver implementations were confused about the interpretation of the framerate field, but hopefully this will be consistent everywhere once 0.40.0 is released. (cherry picked from commit ff35aa8ca4069bf1543adeec4c28e51e4a012eee)
* vaapi_h264: Enable VBR modeMark Thompson2017-02-08
| | | | | | | | | | Default to using VBR when a target bitrate is set, unless the max rate is also set and matches the target. Changes to the Intel driver mean that min_qp is also respected in this case, so set a codec default to unset the value rather than using the current default inherited from the MPEG-4 part 2 encoder. (cherry picked from commit eddfb57210298a0a94472794485400a3a6c76196)
* vaapi_encode: Support VBR modeMark Thompson2017-02-08
| | | | | | | | This includes a backward-compatibility hack to choose CBR anyway on old drivers which have no CBR support, so that existing programs will continue to work their options now map to VBR. (cherry picked from commit f033ba470fbab1ff6838666d4d86411effa97b27)
* vaapi_encode: Add MPEG-2 supportMark Thompson2017-02-08
| | | | (cherry picked from commit ca6ae3b77a7e6600e517723b90e57527a47809de)
* vaapi_h264: Scale log2_max_pic_order_cnt_lsb with max_b_framesMark Thompson2017-02-08
| | | | | | | | | Before this change, it was possible to overflow pic_order_cnt_lsb and generate a stream with invalid POC numbering. This makes sure that the field is large enough that a single IDR B* P sequence uses fewer than half the available POC lsb values. (cherry picked from commit 89725a8512721fffd190021ded2d3f5b42e20e2a)
* vaapi_encode: Support forcing IDR frames via AVFrame.pict_typeMark Thompson2017-02-08

* vaapi_encode: Fix GOP sizingMark Thompson2017-02-08
| | | | | | | | This change makes the configured GOP size be respected exactly - previously the value could be exceeded slightly due to flaws in the frame type selection logic. (cherry picked from commit 37fab0661a760b2a9d727939d72e629acee1a6ef)
* vaapi_h265: Fix CFR mode with framerate set in AVCodecContextMark Thompson2017-02-08

* avcodec/flacdsp: Avoid undefined operations in non debug buildsMichael Niedermayer2017-02-04
| | | | | | | | | | | | | | | | | | | | | This fixes ubsan warnings in non debug builds by using unsigned operations in debug builds the correct signed operations are retained so that overflows (which should not occur in valid files and may indicate problems in the DSP code or decoder) can be detected. Alternatively they can be changed to unsigned unconditionally, then its not possible though to detect overflows easily if someone wants to test the DSP code for overflows. The 2nd alternative would be to leave the code as it is and accept that there are undefined operations in the DSP code and that ubsan output is full of them in some cases. Similar changes would be needed in some other DSP routines Suggested-by: Matt Wolenetz <wolenetz@google.com> Signed-off-by: Michael Niedermayer <michael@niedermayer.cc>

* speedhq: fix out-of-bounds writeSteinar H. Gunderson2017-02-02
| | | | | | | | | | | | | Certain alpha run lengths (for SHQ1/SHQ3/SHQ5) could be stored in both long and short versions, and we would only accept the short version, returning -1 (invalid code) for the others. This could cause an out-of-bounds write on malicious input, as discovered by Andreas Cadhalpun during fuzzing. Fix by simply allowing both versions, leaving no invalid codes in the alpha VLC.

* avcodec/atrac3: Add multichannel joint stereo ATRAC3bnnm2017-02-01
| | | | | | | | | | | | | | | | | | | | | | Multichannel joint stereo simply interleaves stereo pairs (6ch: 2ch + 2ch + 2ch), so each pair is decoded separatedly. *** To test my changes, I converted examples to wav with ffmpeg.exe (old and new), and compared them to see they are byte-exact. Regular 2ch files (JS and normal) were straightforward to test. For multichannel, to check each JS pair is correctly decoded separatedly I did: - manually demux 6ch.msf into 3 pairs and convert them (2ch_1.wav + 2ch_2.wav + 2ch_3.wav) - convert the 6ch.msf file to wav (with my changes) - manually demux the 6ch.wav into 3 pairs (6ch_d1.wav + 6ch_d2.wav + 6ch_d3.wav) - compare each pair (ex. 2ch_3.wav vs 6ch_d3.wav): all pairs are byte-exact. The new code just processes each JS pair separatedly, there are no algorithm changes. It could be improved a bit but I'm not sure about typical styles. I've only seen 6ch .MSF (probably the AT3 spec only supports 2ch audio). Signed-off-by: bnnm <bananaman255@gmail.com>
