* x86inc improvements for 64-bitHenrik Gramner2012-04-11
| | | | | | | | | | | | Add support for all x86-64 registers Prefer caller-saved register over callee-saved on WIN64 Support up to 15 function arguments Also (by Ronald S. Bultje) Fix up our asm to work with new x86inc.asm. Signed-off-by: Ronald S. Bultje <rsbultje@gmail.com> Signed-off-by: Justin Ruggles <justin.ruggles@gmail.com>
* interplayvideo: fix av_dlog parameter type mismatchDiego Biurrun2012-04-11
| | | | libavcodec/interplayvideo.c:909:13: warning: format ‘%p’ expects argument of type ‘void *’, but argument 7 has type ‘GetByteContext’ [-Wformat]
* Drop some pointless #ifdefs.Diego Biurrun2012-04-10
| | | | The files are only compiled if the #ifdef conditions are met.
* 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.

| | | | 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>

* 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
