2011-12-21lavc: always align height by 32 pixelRafaël Carré
Interlaced content for most codec requires it. This patch is a stop-gap pending a serious rework to support codecs with non 16 pixel macroblocks. Signed-off-by: Luca Barbato <lu_zero@gentoo.org>

2011-12-21mpegvideo_enc: separate declarations and statementsDiego Biurrun
libavcodec/mpegvideo_enc.c:1209: warning: ISO C90 forbids mixed declarations and code
2011-12-21vp3: Reorder some functions to fix VP3 build with Theora disabled.Diego Biurrun
2011-12-21build: fix standalone compilation of ADX encoderDiego Biurrun
The encoder depends on the common code, so link against it.
2011-12-21build: fix standalone compilation of ADPCM decodersDiego Biurrun
The generic ADPCM codes depends on the ADPCM data tables.

2011-12-20vc1dec: Use the right pointer type for the tmp pointerMartin Storsjö
This fixes warnings about assignment from incompatible pointer type. Signed-off-by: Martin Storsjö <martin@martin.st>
2011-12-20h264: clear trailing bits in partially parsed NAL unitsJanne Grunau
Trailing bits are likely to be non-zero if the NAL unit is truncated. Clearing the bits make overreads of the bitstream less likely in this case. Fixes playback of http://streams.videolan.org/streams/mp4/Mr_MrsSmith-h264_aac.mp4 which has a forbidden byte sequence of 0x00 0x00 0x00 in it SPS.

2011-12-19Revert "h264: skip start code search if the size of the nal unit is known"Janne Grunau
This reverts commit 87eebb3454ff0cd6af6ebf9e1d31bdfd1c3b601b.
2011-12-19h264: skip start code search if the size of the nal unit is knownJanne Grunau
Start code emulation prevention is only required in Annex B bytestream packed NAL units. For other coding formats the size is already known. Looking for a start code prefix can result in false positives like in http://streams.videolan.org/streams/mp4/Mr_MrsSmith-h264_aac.mp4 which has a false positive in the SPS.

2011-12-19cljr: Check if width and height are positive integersShitiz Garg
Width and height might get passed as 0 and would cause floating point exceptions in decode_frame. Fixes bugzilla #149 Signed-off-by: Janne Grunau <janne-libav@jannau.net>
2011-12-19avcodec: deprecate AVFrame.ageMans Rullgard
This was intended as an optimisation for skipped blocks in MPEG2 P-frames and never used elsewhere. Removing this "optimisation" speeds up MPEG2 decoding by 1-2% (ARM Cortex-A9). Signed-off-by: Mans Rullgard <mans@mansr.com>
2011-12-184xm: remove unneeded check for remaining unused data.Justin Ruggles
This is unnecessary complication that only prints a message and does not affect decoding.
2011-12-18tmv decoder: set correct pix_fmtUoti Urpala
Previously the decoder only worked if the user had set avctx->pix_fmt manually. For some reason the libavformat tmv demuxer sets this, so the problem was not visible in avplay etc. Signed-off-by: Ronald S. Bultje <rsbultje@gmail.com>

2011-12-17mp3dec: hack: fix decoding with safe bitstream readerMans Rullgard
The buffer splicing relies on the bitstream reader over-reading the end of the buffer as declared in init_get_bits(), although more data is actually present. Manually moving the bitstream boundary after init_get_bits() allows this to work as expected. Signed-off-by: Mans Rullgard <mans@mansr.com>
2011-12-17adpcm: Check for channels to be a non-zero integerShitiz Garg
channels would be 0 sometimes and would cause floating point exception Fixes bugzilla #124 Signed-off-by: Justin Ruggles <justin.ruggles@gmail.com>
2011-12-17get_bits: introduce safe bitreading to prevent overreads.Ronald S. Bultje
When turned on, H264/CAVLC gets ~15% (CVPCMNL1_SVA_C.264) slower for ultra-high-bitrate files, or ~2.5% (CVFI1_SVA_C.264) for lower-bitrate files. Other codecs are affected to a lesser extent because they are less optimized; e.g., VC-1 slows down by less than 1% (all on x86). The patch generated 3 extra instructions (cmp, cmovae and mov) per call to get_bits(). The performance penalty on ARM is within the error margin for most files, up to 4% in extreme cases such as CVPCMNL1_SVA_C.264. Based on work (for GCI) by Aneesh Dogra <lionaneesh@gmail.com>, and inspired by patch in Chromium by Chris Evans <cevans@chromium.org>.
2011-12-17get_bits: remove A32 variantMans Rullgard
The A32 bitstream reader variant is only used on ARMv5 and for Prores due to the larger bit cache this decoder requires. In benchmarks on ARMv5 (Marvell Sheeva) with gcc 4.6, the only statistically significant difference between ALT and A32 is a 4% advantage for ALT in FLAC decoding. There is thus no (longer) any reason to keep the A32 reader from this point of view. This patch adds an option to the ALT reader increasing the bit cache to 32 bits as required by the Prores decoder. Benchmarking shows no significant change in speed on Intel i7. Again, the A32 reader fails to justify its existence. Signed-off-by: Mans Rullgard <mans@mansr.com>

2011-12-16h264: don't drop B-frames after next keyframe on POC reset.Ronald S. Bultje
The keyframe after a POC reset may not be the first to be returned to the user. Therefore, don't reset the expected next POC once we return a keyframe to the user, but once we know that the next frame in the return-queue is a keyframe.

2011-12-15libgsm: Reset the MS mode of GSM in the flush functionMartin Storsjö
The mode is set in libgsm_decode_init, but the decoder object is simply destroyed and recreated in the flush function - therefore the mode has to be set again. This fixes playback using the libgsm_ms decoder in avplay. Signed-off-by: Martin Storsjö <martin@martin.st>
