* vc2enc: redistribute leftover bytesRostislav Pehlivanov2016-02-281-5/+55
| | | | | | | | | | | 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 <[email protected]>

* vc2enc: carry over quantization index across frames as a starting pointRostislav Pehlivanov2016-02-281-6/+6
| | | | | | | | 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 <[email protected]>
* vc2enc: use 32 bits for quantized coefficients LUTRostislav Pehlivanov2016-02-281-9/+9

* mjpegdec: Do not assume unused plane pointer are NULL.Reimar Döffinger2016-02-281-3/+8
| | | | | | | | | | | | | 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 Döffinger2016-02-281-2/+2
| | | | | | | | | | | | | | | | | 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 <[email protected]>

* configure: add direct detection of libopencvAndreas Cadhalpun2016-02-281-1/+2
| | | | | | | | | | | | | | | | 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.
