* config.asm: change %ifdef directives to %if directives.Ronald S. Bultje2012-01-27
| | | | This allows combining multiple conditionals in a single statement.

* vc1dec.c: Don't use uninitialized values of dmv_[x, y]Mashiat Sarker Shakkhar2012-01-27
| | | | | | | | | | | MVDATA may or may not be transmitted. If it is not, both dmv_x and dmv_y is to be assumed zero. This may not trigger wrong picture in all systems, but it's a bug nevertheless. Fixes SA10116.vc1 on my 64-bit Windows 7. Signed-off-by: Ronald S. Bultje <rsbultje@gmail.com>
* mjpegbdec: Fix overflow in SOS.Alex Converse2012-01-26

* vc1: always read the bfraction element for interlaced fieldsHendrik Leppkes2012-01-26
| | | | | | | Previously, it would not be read if refdist_flag was not set, however according to the spec and the reference decoder, it should always be read. Signed-off-by: Kostya Shishkov <kostya.shishkov@gmail.com>
* wma: Clip WMA1 and WMA2 frame length to 11 bits.Alex Converse2012-01-25
| | | | | | | | | | | | The MDCT buffers in the decoder are only sized for up to 11 bits. The reverse engineered documentation for WMA1/2 headers say that that for all samplerates above 32kHz 11 bits are used. 12 and 13 bit support were added for WMAPro. I was unable to make any Microsoft tools generate a test file at a samplerate above 48kHz. Discovered by: Mateusz "j00ru" Jurczyk and Gynvael Coldwind CC: libav-stable@libav.org
* rv20: prevent calling ff_h263_decode_mba() with unset height/widthJanne Grunau2012-01-25
| | | | | | | Prevents a crash of VLC during playback of a invalid matroska file, found by John Villamil <johnv@matasano.com>. CC: libav-stable@libav.org

* dsputil: use vertical component for drawing bottom edge.Ronald S. Bultje2012-01-25
| | | | | Current code only writes 8 pixels of vertical edge for YUV422, which causes MC artifacts when subsequent frames use data from that edge.
* aacenc: Fix identification padding when the bitstream is already aligned.Alex Converse2012-01-24
|
* aacenc: Write correct length for long identification strings.Michael Niedermayer2012-01-24
| | | | | | | When the length is the escape value (15), the new length is calculated by 15 + get_bits(8) - 1. Signed-off-by: Alex Converse <alex.converse@gmail.com>
* adpcm_ima_ws: fix stereo decodingJustin Ruggles2012-01-24
| | | | | Stereo ADPCM IMA WS is planar for VQA version 3 and 2-sample interleaved for VQA version 2.
* avcodec: add a new codec_id for CRYO APC IMA ADPCM.Justin Ruggles2012-01-24
| | | | | The stereo layout and extradata is significantly different from that in Westwood IMA ADPCM, so a separate codec_id is warranted.
* lavc: postpone the removal of AVCodecContext.request_channels.Anton Khirnov2012-01-24
| | | | | | Although it has been deprecated for a long time, its intended replacement (request_channel_layout) is not actually used anywhere, so request_channels is currently the only way to access that functionality.
* lavc: postpone removing old audio encoding and decoding APIAnton Khirnov2012-01-24
| | | | It has been deprecated only recently.

* vc1: don't read the interpfrm and bfraction elements for interlaced framesHendrik Leppkes2012-01-23

* threads: change the default for threads back to 1Janne Grunau2012-01-21
| | | | | | Using threaded decoding by default breaks backward compatibility if AVHWAccel is used or if an appliction sets threadunsafe callbacks. Avconv and avplay still use -threads auto if not specified.
* threads: update slice_count and slice_offset from user contextJanne Grunau2012-01-21
| | | | | They are used to signal the number of slices and offsets of each slice out of band to the decoder.

* mpegvideo: fix invalid memory access for small video dimensionsJohn Brooks2012-01-21
| | | | | | | | | | When either video dimension is only one macroblock, subtractions based on v_edge_pos and the macroblock size may be negative. In that situation, an unsigned comparison isn't sufficent to test for MV overruns, because a limit of (unsigned)-1 will let any other value pass. Signed-off-by: Anton Khirnov <anton@khirnov.net>
