Ronald S. Bultje	b27b54de31	arm/h264pred: add missing argument type.	14 years ago
Oskar Arvidsson	19a0729b4c	Adds 8-, 9- and 10-bit versions of some of the functions used by the h264 decoder. This patch lets e.g. dsputil_init chose dsp functions with respect to the bit depth to decode. The naming scheme of bit depth dependent functions is <base name>_<bit depth>[_<prefix>] (i.e. the old clear_blocks_c is now named clear_blocks_8_c). Note: Some of the functions for high bit depth is not dependent on the bit depth, but only on the pixel size. This leaves some room for optimizing binary size. Preparatory patch for high bit depth h264 decoding support. Signed-off-by: Ronald S. Bultje <rsbultje@gmail.com>	14 years ago

Mans Rullgard	d461a47317	Rearrange MpegEncContext to simplify access from asm This moves the fields needed by asm near the top, before any structs or other members which complicate the offset calculation. Modifying other structs will no longer require updating the offsets, and the asm code is slightly simpler due to the smaller offsets. Signed-off-by: Mans Rullgard <mans@mansr.com>	14 years ago

Jason Garrett-Glaser	4a384de5b8	Split h264dsp and h264pred in configure. Many H.264 derivatives, like RV40 and VP8, use the H.264 prediction functions but not the weight/loopfilter functions. This should reduce the size of builds with one of these derivatives but without H.264 decoding itself. Originally committed as revision 24741 to svn://svn.ffmpeg.org/ffmpeg/trunk	14 years ago
