2016-08-03libavcodec/dnxhd: Enable 12-bit DNxHR support.Steven Robertson
10- and 12-bit DNxHR use the same DC coefficient decoding process and VLC table, just with a different shift value. From SMPTE 2019-1:2016, 8.2.4 DC Coefficient Decoding: "For 8-bit video sampling, the maximum value of η=11 and for 10-/12-bit video sampling, the maximum value of η=13." A sample file will be uploaded to show that with this patch, things decode correctly: dnxhr_hqx_12bit_1080p_smpte_colorbars_davinci_resolve.mov Signed-off-by: Steven Robertson <steven@strobe.cc> Signed-off-by: Michael Niedermayer <michael@niedermayer.cc>

2016-08-02af_hdcd: Process stereo channels together, fix #5727Burt P
Issue #5727: gain adjustment should only be applied if matching gain value from a valid packet in both channels. The existing functions process each channel separately, so it was not possible. * New versions of hdcd_process(), hdcd_scan(), hdcd_integrate() named hdcd_*_stereo() that process both channels together. * target_gain applied will be the last matching target_gain. * The old single channel functions remain as an option. They can be used by: -af hdcd=process_stereo=0. Signed-off-by: Burt P <pburt0@gmail.com> Signed-off-by: Michael Niedermayer <michael@niedermayer.cc>

2016-07-30avfilter/af_stereowiden: fix read/write past the end of bufferAlexey Tourbin
The stereowiden filter uses a buffer, s->buffer[], and a pointer within the buffer, s->write, to implement inter-channel delays. The loop which applies the delayed samples turns out to be faulty. 109 for (n = 0; n < in->nb_samples; n++, src += 2, dst += 2) { 110 const float left = src[0], right = src[1]; 111 float *read = s->write + 2; 112 113 if (read > s->buffer + s->length) 114 read = s->buffer; 115 116 dst[0] = drymix * left - crossfeed * right - feedback * read[1]; 117 dst[1] = drymix * right - crossfeed * left - feedback * read[0]; 118 119 s->write[0] = left; 120 s->write[1] = right; 121 122 if (s->write == s->buffer + s->length) 123 s->write = s->buffer; 124 else 125 s->write += 2; 126 } For one, the buffer gets written past its end in lines 119-120, before the bound check is done in lines 122-123. This can be easily confirmed by valgrind. ==3544== Invalid read of size 4 ==3544== at 0x593B41: filter_frame (af_stereowiden.c:116) ==3544== Address 0xb1b03c4 is 4 bytes after a block of size 7,680 alloc'd ==3544== ==3544== Invalid read of size 4 ==3544== at 0x593B66: filter_frame (af_stereowiden.c:117) ==3544== Address 0xb1b03c0 is 0 bytes after a block of size 7,680 alloc'd ==3544== ==3544== Invalid write of size 4 ==3544== at 0x593B79: filter_frame (af_stereowiden.c:119) ==3544== Address 0xb1b03c0 is 0 bytes after a block of size 7,680 alloc'd ==3544== ==3544== Invalid write of size 4 ==3544== at 0x593B7D: filter_frame (af_stereowiden.c:120) ==3544== Address 0xb1b03c4 is 4 bytes after a block of size 7,680 alloc'd Also, using two separate pointers, s->write and read = s->write + 2, does not seem to be well thought out. To apply the delay of s->buffer[], it is enough to read the delayed samples at the current position within the buffer, and then to store new samples at the same current position. Thus the application of delayed samples can probably be best described with a single pointer s->cur. I also introduce a minor change to ensure that the size of s->buffer[] is always a multiple of 2. Since the delay parameter is a float, it is otherwise possible to trick the code into allocating off-by-one buffer.

2016-07-29avfilter: Add new format for PSNR stats logLucas Cooper
Add an AVOption stats_version with a new header for V2 stats, which specifies the stats log version and lists the fields that will be present in the log (to ease parsing). The primary motivation is to facilitate the addition of optional fields to the log without breaking backwards compatibility, while making the logs easier to parse.
