| | | | | | | Also checking AVFilterLink->type is AVMEDIA_TYPE_AUDIO before calling av_get_sample_fmt_name() on AVFilterLink->format. Signed-off-by: Burt P <pburt0@gmail.com>
* af_hdcd: Add analyze modeBurt P2016-08-08
| | | | | | | | | | A new mode, selected by filter option, to aid in analysis of HDCD encoded audio. In this mode the audio is replaced by a solid tone and the amplitude is adjusted to signal some specified aspect of the process. The output file can be loaded in an audio editor alongside the original, where the user can see where different features or states are present. Signed-off-by: Burt P <pburt0@gmail.com>

* af_hdcd: Warn if there is any resampling or format conversion in the link chainBurt P2016-08-01
| | | | | | | | | HDCD is only encoded in s16@44100Hz. Scan the chain of AVFilterLinks for any resampling or format conversion/truncation that might cause problems for the filter and issue warnings. Signed-off-by: Burt P <pburt0@gmail.com> Signed-off-by: Michael Niedermayer <michael@niedermayer.cc>
* af_hdcd: Process stereo channels together, fix #5727Burt P2016-08-01
| | | | | | | | | | | | | | | 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>

* avfilter/af_stereowiden: fix read/write past the end of bufferAlexey Tourbin2016-07-30
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | 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.
* avfilter: Add new format for PSNR stats logLucas Cooper2016-07-29
| | | | | | | | | | | | 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.
