* | avcodec/mjpegdec: Add some sanity checks to ljpeg_decode_rgb_scan()Michael Niedermayer2013-09-05
| | | | | | | | | | | | | | These prevent the rgb ljpeg code from being run on parameters that it doesnt support. No testcase available but it seems possible to trigger these. Signed-off-by: Michael Niedermayer <michaelni@gmx.at>

| | | | | | | | | | | | This ensures that no uninitialized bytes cause non-deterministic behavior. Signed-off-by: Michael Niedermayer <michaelni@gmx.at>
* | lavc/avfft: init context to 0.Nicolas George2013-09-04
| | | | | | | | Prevent an invalid free in case of init failure.
* | lavc/libvorbisdec: do not return empty frames.Nicolas George2013-09-04
| | | | | | | | | | | | Some parts of the code have been known to react badly to empty frames; they should not, but there is no need to take risks.

* | avcodec: add emuedge_linesize_typeMichael Niedermayer2013-09-04
| | | | | | | | | | | | | | | | | | | | Currently all uses of the emu edge code as well as the code itself assume int linesize changing some but not changing all would introduce a security issue once all use this typedef a simple search and replace can be done to switch them all to ptrdiff_t Signed-off-by: Michael Niedermayer <michaelni@gmx.at>

| * alac: Check that the channels fit at the given offsetMartin Storsjö2013-09-03
| | | | | | | | | | | | | | | | | | | | | | | | | | The code tries to decode a number of channels at the offset given by the ff_alac_channel_layout_offsets table. Even if the number of channels decoded so far doesn't exceed the total number of channels, we need to check that we actually can decode that number of channels at this offset as well.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Remove the header decoding for PCM audio from mpeg.c and the 20/24bit parts from pcm.c and merge them into a new decoder in pcm-dvd.c. The decoder has added support for samples that span multiple packets and modified 20/24bit group decoding. Both is needed to decode samples that have been generated with DVD-Lab Pro 2. The decoding of 16bit PCM and two channel 24bit is identical to before. No other samples are known to verify the correctness of the encoding this software does. The complete list of tested formats is 48kHz/16bit/2-8 channels 48kHz/24bit/2-5 channels 96kHz/16bit/2-4 channels 96kHz/24bit/2 channels Signed-off-by: Luca Barbato <lu_zero@gentoo.org>
