Andreas Rheinhardt	afc95a10ac	avcodec/h264dsp, h264idct: Fix lengths of array parameters Fixes many -Warray-parameter warnings from GCC 11. Signed-off-by: Andreas Rheinhardt <andreas.rheinhardt@outlook.com>	3 years ago
Martin Storsjö	0676de935b	arm: Implement a NEON version of 422 h264_h_loop_filter_chroma Previously, the 420 version was used even for 422. This fixes occasional checkasm failures. Signed-off-by: Martin Storsjö <martin@martin.st>	6 years ago
James Almer	7b9ca44cbc	arm/h264dsp: change loop filter stride argument to ptrdiff_t This was missed in `d5d699ab6e` Signed-off-by: James Almer <jamrial@gmail.com>	6 years ago
Carl Eugen Hoyos	f9f9ae1b77	lavc/arm: Use the neon vertical chroma loop filter also for H.264 4:2:2.	10 years ago

Ben Avison	db7f1c7c5a	h264: Move start code search functions into separate source files. This permits re-use with parsers for codecs which use similar start codes. Signed-off-by: Luca Barbato <lu_zero@gentoo.org>	10 years ago

Martin Storsjö	79fce1ec8a	arm: Avoid using the 'setend' instruction on ARMv7 and newer This instruction is deprecated on ARMv8, and it is serializing on some ARMv7 cores as well [1].

Jason Garrett-Glaser	c90b94424c	4:4:4 H.264 decoding support Note: this is 4:4:4 from the 2007 spec revision, not the previous (now deprecated) 4:4:4 mode in H.264.	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

Måns Rullgård	fa2d5d54b9	ARM: NEON H264 8x8 IDCT Parts by David Conrad. Originally committed as revision 24706 to svn://svn.ffmpeg.org/ffmpeg/trunk	14 years ago
Måns Rullgård	30d87675f1	ARM: remove some unnecessary ifdefs, fix implicit declaration warnings Originally committed as revision 23437 to svn://svn.ffmpeg.org/ffmpeg/trunk	15 years ago
Måns Rullgård	4693b031a3	Move H264 dsputil functions into their own struct This moves the H264-specific functions from DSPContext to the new H264DSPContext. The code is made conditional on CONFIG_H264DSP which is set by the codecs requiring it. The qpel and chroma MC functions are not moved as these are used by non-h264 code.
