ffmpeg_videotoolbox: skip memory copy if hwaccel_output_format match
Simple test results:
Command:
./ffmpeg -y -hwaccel videotoolbox -hwaccel_output_format videotoolbox_vld \
-i test.mp4 -an -c:v h264_videotoolbox -benchmark out.mp4
Before:
frame= 1221 fps= 66 q=-0.0 Lsize= 3144kB time=00:00:20.33 bitrate=1266.6kbits/s dup=4 drop=0 speed= 1.1x
bench: utime=2.714s stime=1.218s rtime=18.574s
After:
frame= 1221 fps=137 q=-0.0 Lsize= 3144kB time=00:00:20.33 bitrate=1266.4kbits/s dup=4 drop=0 speed=2.28x
bench: utime=1.450s stime=1.440s rtime=8.924s
It has limited usecase since there is no video filter support, so
a log message is added to notify the user.
