* lavc/videotoolboxenc: remove *_NULLABLE annotations; fixes pre-10.11 buildRodger Combs2016-03-02
| | | | | | | These macros were added in OS X 10.11, and the file compiles without warnings on both 10.10 and 10.11 with them removed. Thanks to mark4o on IRC for pointing out the failure and testing the patch.

* Move the |die| member of FrameThreadContext to PerThreadContext.Wan-Teh Chang2016-03-01
| | | | | | | | | | | This fixes a data race warning by ThreadSanitizer. FrameThreadContext.die is read by all the worker threads but is not protected by any mutex. Move it to PerThreadContext so that each worker thread reads its own copy of |die|, which can then be protected with PerThreadContext.mutex.

* vc2enc: fix packet underallocation and minimum bitrate with interlacingRostislav Pehlivanov2016-03-01
| | | | | | | | | This was a regression introduced by commit e7345abe052 which enabled full use of the allocated packet but due to the overhead of using field coding the buffer was too small and triggered warnings and crashes. Signed-off-by: Rostislav Pehlivanov <atomnuker@gmail.com>

* vc2enc: redistribute leftover bytesRostislav Pehlivanov2016-02-28
| | | | | | | | | | | This commit redistributes the leftover bytes amongst the top 150 slices in terms of size (in the hopes that they'll be the ones pretty bitrate starved). A more perceptual method would probably need to cut bits off from slices which don't need much, but that'll be implemented later. Signed-off-by: Rostislav Pehlivanov <atomnuker@gmail.com>

* vc2enc: carry over quantization index across frames as a starting pointRostislav Pehlivanov2016-02-28
| | | | | | | | Previously a global average was used. Using the previous quantizer resulted in a fairly significant speedup as slice size selection settled down quicker. Signed-off-by: Rostislav Pehlivanov <atomnuker@gmail.com>

| | | | | | | | | | Check that the required plane pointers and only those are set up. Currently does not enforce anything for the palette pointer of pseudopal formats as I am unsure about the requirements. Signed-off-by: Reimar Döffinger <Reimar.Doeffinger@gmx.de>
* mjpegdec: Do not assume unused plane pointer are NULL.Reimar Döffinger2016-02-28
| | | | | | | | | | | | | We do neither document nor check such a requirement and for application-provided get_buffer2 they could contain the result of a malloc(0) or whatever value they had previously. This fixes a use-after-free in e.g. MPlayer: https://trac.mplayerhq.hu/ticket/2262 We might want to consider changing the (documented) API in addition though.

* mss2: Fix buffer overflow.Reimar Döffinger2016-02-28
| | | | | | | | | | | | | | | | | Reported as https://trac.mplayerhq.hu/ticket/2264 but have not been able to reproduce with FFmpeg-only. I have no idea what coded_height is used for here exactly, so this might not be the best fix. Fixes the following chain of events: ff_mss12_decode_init sets coded_height while not setting height. ff_mpv_decode_init then copies coded_height into MpegEncContext height. This is then used by init_context_frame to allocate the data structures. However the wmv9rects are validated/initialized based on avctx->height, not avctx->coded_height. Thus the decode_wmv9 function will try to decode a larger video that we allocated data structures for, causing out-of-bounds writes. Signed-off-by: Reimar Döffinger <Reimar.Doeffinger@gmx.de>

* vc2enc: calculate the minimum slice size only onceRostislav Pehlivanov2016-02-26
| | | | | | | This commit moves the minimum bits per slice calculations outside of the rate control function as it is identical for every slice. Signed-off-by: Rostislav Pehlivanov <atomnuker@gmail.com>
* vc2enc: halve allocated table size, refactor and optimize quantizationRostislav Pehlivanov2016-02-26
| | | | | | | | | | | | | Since coefficients differ only in the last bit when writing to the bitstream it was possible to remove the sign from the tables, thus halving them. Also now all quantization is done in the unsigned domain as the sign is completely separate, which gets rid of the need to do quantization on 32 bit signed integers. Overall, this slightly speeds up the encoder depending on the machine. The commit still generates bit-identical files as before the commit. Signed-off-by: Rostislav Pehlivanov <atomnuker@gmail.com>
