* rv40dsp x86: use only one register, for both increment and loop counterChristophe GISQUET2012-04-10
| | | | | | Around 10 cycles faster for luma. Signed-off-by: Ronald S. Bultje <rsbultje@gmail.com>
* rv40dsp: implement prescaled versions for biweight.Christophe GISQUET2012-04-10
| | | | | | | | | | Quite often, the original weights are multiple of 512. By prescaling them by 1/512 when they are computed (once per frame), no intermediate shifting is needed, and no prescaling on each call either. The x86 code already used that trick.

* lavc doxy: replace \ with /Anton Khirnov2012-04-09
| | | | | It's the more proper symbol to use and it prevents doxygen from thinking it's a command.

| | | | | Also move AV_PKT_DATA_PARAM_CHANGE/AV_PKT_DATA_H263_MB_INFO to the proper place.

* avcodec: use align == 0 for default alignment in avcodec_fill_audio_frame()Justin Ruggles2012-04-09
| | | | Use default alignment in audio_get_buffer()
* avcodec: validate the channel layout vs. channel count for decodersJustin Ruggles2012-04-08
| | | | | Set avctx->channel_layout to 0 if the channel count does not match avctx->channels.
* vaapi: mpeg2: fix slice_vertical_position calculation.Gwenole Beauchesne2012-04-08
| | | | | | | | | | | | | | | | | VASliceParameterBufferMPEG2.slice_vertical_position shall express the slice vertical position from the original bitstream. The HW decoder will correctly decode to the right line computed from the appropriate top_field_first and is_first_field flags. This patch aligns with DXVA's definition, which is what most HW and drivers expect. In particular, Intel PowerVR (Cedarview et al.) and NVIDIA (through VA-to-VDPAU layer). Since it looks more complex to fix binary drivers, I aligned the Intel Gen driver (Sandy Bridge et al.) to this behaviour, while maintaining compatibility with codec layers not providing this patch yet.

* hwaccel: mpeg2: decode first field, if requested.Gwenole Beauchesne2012-04-08
| | | | | | | | | | | | | | | | | | | If user opted to present fields as they come, then the first field picture needs to be submitted to the HW for decoding. In particular, this fixes MPEG-2 decoding of interlaced streams. Tested on Intel Cedar Trail, Sandy Bridge and Ivy Bridge platforms. Someone reported on the ffmpeg-devel@ list this also works on DXVA (Windows) and other Linux platforms (NVIDIA, through the VA wrapper). This also means a similar patch to non-hwaccel VDPAU may be necessary. Note: I believe the SLICE_FLAG_ALLOW_FIELD is useless since the first field shall always be submitted to the HW anyway. Nobody uses HW accels (dxva, vaapi, vdpau, etc.) without that flag though. Signed-off-by: Gwenole Beauchesne <gwenole.beauchesne@intel.com> Signed-off-by: Martin Storsjö <martin@martin.st>

* avcodec: remove avcodec_guess_channel_layout()Justin Ruggles2012-04-05
| | | | | It is not public because the header is not installed, and its functionality has been replaced by av_get_default_channel_layout().

* truemotion: forbid invalid VLC bitsizes and token values.Ronald S. Bultje2012-03-29
| | | | | | | | | | | | SHOW_UBITS() is only defined up to n_bits is 25, therefore forbid values larger than this in get_vlc2() (max_bits). tokens[][] can be used as an index in deltas[], which has a size of 64, so ensure the values are smaller than that. This prevents crashes on corrupt bitstreams. Found-by: Mateusz "j00ru" Jurczyk and Gynvael Coldwind CC: libav-stable@libav.org

| | | | | | Looks like some LAME versions produce dual stereo mode MP3s with flags for intensity and middle stereo set. In this mode those flags should be ignored like the reference decoder and derived ones do.
