* libspeex: Add a private option for enabling VADDmitry Samonenko2012-10-03
| | | | | | | Speex detects non-speech periods and encodes them with just enough bits to reproduce the background noise, aka ``comfort noise generation''. Signed-off-by: Martin Storsjö <martin@martin.st>
* ARM: set Tag_ABI_align_preserved in all asm filesMans Rullgard2012-10-02
| | | | | | | | All our ARM asm preserves alignment so setting this attribute in a common location is simpler. This removes numerous warnings when linking with armcc. Signed-off-by: Mans Rullgard <mans@mansr.com>

* ac3dec: ensure get_buffer() gets a buffer for the correct number of channelsJustin Ruggles2012-10-01
| | | | | | | | | | | If there is an error during frame parsing, but AVCodecContext.channels was changed and AC3DecodeContext.out_channels was set previously, the two may not match. Fixes CVE-2012-2802 Found-by: Mateusz "j00ru" Jurczyk and Gynvael Coldwind CC: libav-stable@libav.org
* h264: avoid stuck buffer pointer in decode_nal_unitsJindřich Makovička2012-09-29
| | | | | | | | | | | | | | | | | | When decode_nal_units() previously encountered a NAL_END_SEQUENCE, and there are some junk bytes left in the input buffer, but no start codes, buf_index gets stuck 3 bytes before the end of the buffer. This can trigger an infinite loop in the caller code, eg. in try_decode_trame(), as avcodec_decode_video() then keeps returning zeroes, with 3 bytes of the input packet still available. With this change, the remaining bytes are skipped so the whole packet gets consumed.

* mpeg12: fix the semantics of the int* parameter of decode()Anton Khirnov2012-09-29
| | | | It is got_output, not data_size.
* mpeg12: move mpeg_decode_frame() lowerAnton Khirnov2012-09-29
| | | | Avoids a forward declaration of decode_chunks().
* avsdec: Set dimensions instead of relying on the demuxer.Michael Niedermayer2012-09-29
| | | | | | | | | | | The decode function assumes that the video will have those dimensions. Fixes CVE-2012-2801 CC:libav-stable@libav.org Found-by: Mateusz "j00ru" Jurczyk and Gynvael Coldwind Signed-off-by: Anton Khirnov <anton@khirnov.net>
