qsv: adding Multi Frame Encode support
Starting from API 1.25 helps to improve performance of the simultaneous
encode, 1:N scenario, like:
./avconv -y -hwaccel qsv -c:v h264_qsv -r 30000/1001 -i
~/bbb_sunflower_1080p_60fps_normal.mp4 -vframes 600 -an \
-filter_complex "split=2[s1][s2]; [s1]scale_qsv=1280:720[o1];
[s2]scale_qsv=960:540[o2]" \
-map [o1] -c:v h264_qsv -b:v 3200k -minrate 3200k -maxrate 3200k -f
rawvideo /tmp/3200a.264 \
-map [o2] -c:v h264_qsv -b:v 1750k -minrate 1750k -maxrate 1750k -f
