* prores: initialise encoder and decoder parts only when neededKostya Shishkov2012-02-17

* swscale: make monowhite/black RGB-independent.Ronald S. Bultje2012-02-16
| | | | | | Disadvantage is that it no longer allows modifying brightness through adjustment of the RGB lookup table. Advantage is that now monowhite/black no longer need to be identified as a RGB format.
* flac: fix infinite loops on all-zero input or end-of-stream.Ronald S. Bultje2012-02-16
| | | | | Found-by: Mateusz "j00ru" Jurczyk and Gynvael Coldwind CC: libav-stable@libav.org
* wmapro: change max. block size to 13 bits.Ronald S. Bultje2012-02-16
| | | | | | | WMApro actually support 13-bits block sizes (potentially even up to 14), and thus we should support that also. If we get block sizes beyond what the decoder can handle (14 is possible depending on s->decode_flags), error out instead of crashing.
* shorten: Use separate pointers for the allocated memory for decoded samples.Michael Niedermayer2012-02-16
| | | | | | | | | | | Fixes invalid free() if any of the buffers are not allocated due to either not decoding a header or an error prior to allocating all buffers. Fixes CVE-2012-0858 CC: libav-stable@libav.org Signed-off-by: Michael Niedermayer <michaelni@gmx.at> Signed-off-by: Justin Ruggles <justin.ruggles@gmail.com>
* atrac3: Fix crash in tonal component decoding.Michael Niedermayer2012-02-16
| | | | | | | | | | | | Add a check to avoid writing past the end of the channel_unit.components[] array. Bug Found by: cosminamironesei Fixes CVE-2012-0853 CC: libav-stable@libav.org Signed-off-by: Michael Niedermayer <michaelni@gmx.at> Signed-off-by: Justin Ruggles <justin.ruggles@gmail.com>
* ws_snd1: Fix wrong samples counts.Michael Niedermayer2012-02-16
| | | | | | | | | | | This makes the check that avoids overwrite of the samples array actually work properly. fixes CVE-2012-0848 CC: libav-stable@libav.org Signed-off-by: Michael Niedermayer <michaelni@gmx.at> Signed-off-by: Justin Ruggles <justin.ruggles@gmail.com>

* bethsoftvid: synchronize video timestamps with audio sample rateJustin Ruggles2012-02-16
| | | | | | | | According to unofficial documentation, the video rate is locked to the audio sample rate. This results in proper synchronization of audio and video timestamps from the demuxer. This only works if the first audio packet occurs before the first video packet or the audio sample rate is the default rate of 11111 Hz, both of which are true for all samples in our archive.
* bethsoftvid: add audio stream only after getting the first audio packetJustin Ruggles2012-02-16
| | | | | | This avoids initializing a stream with dummy values or when the file does not contain audio. Also set duration for audio packets, using the sample rate as the time base.
* bethsoftvid: Set video packet duration instead of accumulating pts.Justin Ruggles2012-02-16
|
* bethsoftvid: set packet key frame flag for audio and I-frame video packets.Justin Ruggles2012-02-16
| | | | | Fixes avconv video stream copy of bethsoft video, which was skipping all video frames unless the copyinkf option was used.
* bethsoftvid: fix read_packet() return codes.Justin Ruggles2012-02-16
| | | | Use proper AVERROR codes, and return 0 for no error.
* bethsoftvid: pass palette in side data instead of in a separate packet.Justin Ruggles2012-02-16
| | | | | | Update FATE reference to account for now non-existent palette packet. This also fixes the FATE test if frame data is not initialized in get_buffer(), so update comment in avconv accordingly.
* sdp: Ignore RTCP packets when autodetecting RTP streamsMartin Storsjö2012-02-16
| | | | | | | | The rtp demuxer which listens for RTP packets and detects the RTP payload type will currently get confused if the first packet received is an RTCP packet. Thus ignore such packets. Signed-off-by: Martin Storsjö <martin@martin.st>

* mpegaudio: replace memcpy by SIMD codeChristophe GISQUET2012-02-15
| | | | | | | | | | | | By replacing memcpy with an unrolled loop using the alignment knowledge it has, some speedup can be obtained. Before (gcc 4.6.1): ~400 cycles After: ~370 cycles Overall, around 2% speed increase when decoding a 2400s mp3 to f32le. Signed-off-by: Ronald S. Bultje <rsbultje@gmail.com>
