* blowfish: Factorize testing into a separate functionMartin Storsjö2012-10-03

* ARM: use numeric ID for Tag_ABI_align_preservedMans Rullgard2012-10-03
| | | | | | Some old assemblers still in use do not support named tags. Signed-off-by: Mans Rullgard <mans@mansr.com>
* segment: Pass the interrupt callback on to the chained AVFormatContext, tooMartin Storsjö2012-10-02
| | | | | | | | This might not be needed at the moment, but it's good practice to pass it to all chained AVFormatContexts, if it would happen to be used there at a later point. Signed-off-by: Martin Storsjö <martin@martin.st>
* ARM: bswap: drop armcc version of av_bswap16()Mans Rullgard2012-10-02
| | | | | | | This function causes several versions of armcc to miscompile code, and the performance impact is small. Signed-off-by: Mans Rullgard <mans@mansr.com>
* 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>
* ARM: fix Thumb PIC on AppleMans Rullgard2012-10-02
| | | | | | | LDR with register offset and PC as base register is not available in the Thumb instruction set so the addition must be done separately. Signed-off-by: Mans Rullgard <mans@mansr.com>
* nut: add do {} while (0) to GET_VLuca Barbato2012-10-02
| | | | Make it consistent with the other function-like macros.

* 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.
