LOBALHEADER from the flags in rtspenc.c fixes my
problem and I'll very happily submit a patch to that effect, but first
I'd like to know if that is in fact the root of my problem - my
understanding of the RTSP code is very limited and I'd appreciate advice
from someone who knows somethi
As bwdif takes no account of horizontally adjacent pixels the same
code can be used on planes that have multiple components as is used
on single component planes. Update the filtering code to cope with
multi-component planes and add NV12 to the list of supported formats.

Neon RGB24->YUV420P and BGR24->YUV420P functions. Works on 16 pixel
blocks and can do any width or height, though for widths less than 32 or
so the C is likely faster.

Rename swscale conversion functions for converting BGR24 frames to YUV
as bgr24toyuv12 rather than rgb24toyuv12 as that is just confusing and
would be even more confusing with the addition of RGB24 converters.

Also adds a filter_line3 method which on aarch64 neon yields approx 30%
speedup over 2xfilter_line and a memcpy

avfilter/vf_bwdif: Export C filter_intra
Hwaccel doesn't use any of the block strength, pcm, slice address, etc.
arrays which can be >100k each for 4k video. Patch to avoid initial
allocation and zeroing at the start of every frame. On a Pi4 the memsets
can use 10% CPU on 4k 60Hz decode, this fixes that.

Though I guess that if I want that then the device should be bundled

There must be a better way of auto-selecting the hevc_rpi decoder over
the normal s/w hevc decoder, but I became confused by the existing h/w
acceleration framework and what I wanted to do didn't seem to fit in
neatly.
Display should be a proper devic
that probe_arm_arch ends up setting subarch to armv7-a
when the other bits of the script expect armv7a (although gcc wants
armv7-a in -march). Again I am confused by this but I'm not sure what
the right answer is let alone the correct fix. Maybe whoever wrote this
bit of configure could revis

Hi
I enclose a patch that changes av_clip_uintp2 to av_clip_uintp2_c where
the bit depth is variable. This fixes compilation issues if
HAVE_ARMV6_INLINE is 1 and therefore allows arm inline detection to be
fixed too.
