* svq3: Check for any negative return value from ff_h264_check_intra_pred_modeMartin Storsjö2013-09-17
| | | | | | | | Also pass on any returned error code. Reported-by: Mateusz "j00ru" Jurczyk and Gynvael Coldwind CC: libav-stable@libav.org Signed-off-by: Martin Storsjö <martin@martin.st>
* x86: Add an xmm clobbering wrapper for avcodec_encode_video2Martin Storsjö2013-09-16
| | | | | | | This is required since 187105ff8 when we started trying to wrap this function as well. Signed-off-by: Martin Storsjö <martin@martin.st>

* avpacket: Fix error checking in packet_allocMartin Storsjö2013-09-16
| | | | | | | | | | Previously the wrong buffer pointer was checked, when buf instead of *buf was checked. But checking the return value instead is even better. Reported-by: Mateusz "j00ru" Jurczyk and Gynvael Coldwind CC: libav-stable@libav.org Signed-off-by: Martin Storsjö <martin@martin.st>

* proresdec: Properly make sure an index doesn't run past the limitMartin Storsjö2013-09-16
| | | | | | | | | If idx equaled num_coeffs - 1 on entry to the loop, the previous check failed to break out of the loop. Reported-by: Mateusz "j00ru" Jurczyk and Gynvael Coldwind CC: libav-stable@libav.org Signed-off-by: Martin Storsjö <martin@martin.st>

* mathops/x86: work around inline asm miscompilation with GCC 4.8.1Hendrik Leppkes2013-09-15
| | | | | | | | The volatile is not required here, and prevents a miscompilation with GCC 4.8.1 when building on x86 with --cpu=i686 Signed-off-by: Michael Niedermayer <michaelni@gmx.at> Signed-off-by: Derek Buitenhuis <derek.buitenhuis@gmail.com>
* pcm-dvd: Minor leftoversChristian Schmidt2013-09-13
| | | | Drop a pointless branch in uninit and use the compact copyright.
* pcm-dvd: Support channel configuration changesChristian Schmidt2013-09-13
| | | | | | | | | | The sample buffering logic does not take into account that the blocksize could change. Reset the buffer if the channel configuration changes, since if there are leftover samples, it is most likely a broken or misconcatenated stream. This could lead to negative numbers for missing_samples during decoding. Thanks to Michael Niedermeyer for pointing these out.

* mpegvideo: Avoid 32-bit wrapping of linesize multiplicationsMartin Storsjö2013-09-04
| | | | | | | | | This makes sure that linesize * start_y doesn't overflow, so that emulated_edge_mc can get back the original value if needed. Reported-by: Mateusz "j00ru" Jurczyk and Gynvael Coldwind CC: libav-stable@libav.org Signed-off-by: Martin Storsjö <martin@martin.st>

* 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.

* alac: Limit max_samples_per_frameMartin Storsjö2013-09-03
| | | | | | | | | | Otherwise buffer size calculations in allocate_buffers could overflow later, making the code think a large enough buffer actually was allocated. Reported-by: Mateusz "j00ru" Jurczyk and Gynvael Coldwind CC: libav-stable@libav.org Signed-off-by: Martin Storsjö <martin@martin.st>

* pcm_dvd: consolidate pieces from pcm.c and mpeg.cChristian Schmidt2013-08-31
| | | | | | | | | | | | | | | | | | | | 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>

* pcm_bluray: rename pcm-mpeg.c to pcm-bluray.cChristian Schmidt2013-08-31
| | | | | | The original idea was to collect PCM codecs that could appear in various MPEG streams in this file. Discussion in IRC lead to the conclusion that one codec per file would be better and stop the need for #ifdefs.

* apedec: do not buffer decoded samples over AVPacketsRafaël Carré2013-08-28
| | | | | | | | | | | | | | | | | | | | | | | Only consume an AVPacket when all the samples have been read. When the rate of samples output is limited (by the default value of max_samples), consuming the first packet immediately will cause timing problems: - The first packet with PTS 0 will output 4608 samples and be consumed entirely - The second packet with PTS 64 will output the remaining samples (typically, a lot, that's why max_samples exist) until the decoded samples of the first packet have been exhausted, at which point the samples of the second packet will be decoded and output when av_decode_frame is called with the next packet). That means there's a PTS jump since the first packet is 'decoded' immediately, which can be seen with avplay or mplayer: the timing jumps immediately to 6.2s (which is the size of a packet).
