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>

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>

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.

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>

movenc: Timecode in MP4 Although MP4 does not have a concrete specification to store timecode information, the following technical note from Apple describes a way to achieve this via timecode track, similar to how it is done for MOV files. https://developer.apple.com/library/mac/technotes/tn2174/_index.html - Enabled creation of timecode tracks for MP4 in the same way as MOV. - Used nmhd as media information header of timecode track of MP4 instead of gmhd used in MOV, thus avoiding tcmi also, as recommended above. - Bypassed adding source reference field for MP4, as suggested above.

The pkg-config file contains all opencv libraries, not only the neccessary ones. This change makes it possible to use the libopencv-imgproc-dev Debian package instead of libopencv-dev, saving about 200 MB of useless build-dependencies. In particular one doesn't need to install the parts of opencv that depend on ffmpeg libraries.
