Hi, Thank you for your time and careful review. Please let me know if you have
any further suggestions.
Test as follows:
`./ffmpeg -hide_banner -h encoder=mpeg4 2>&1 | head -10`
Encoder mpeg4 [MPEG-4 part 2]:
General capabilities: dr1 delay threads reorderedopaque
Threading capabilities: slice
Supported pixel formats: yuv420p
MPEG4 encoder AVOptions:
-data_partitioning <boolean> E..V....... Use data partitioning.
(default false)
-alternate_scan <boolean> E..V....... Enable alternate scantable.
(default false)
-mpeg_quant <int> E..V....... Use MPEG quantizers instead
of H.263 (from 0 to 1) (default 0)
-b_strategy <int> E..V....... Strategy to choose between
I/P/B-frames (from 0 to 2) (default 0)
-b_sensitivity <int> E..V....... Adjust sensitivity of
b_frame_strategy 1 (from 1 to INT_MAX) (default 40)
`$ ./ffmpeg -hide_banner -h encoder=av1_nvenc 2>&1 | head -10`
Encoder av1_nvenc [NVIDIA NVENC av1 encoder]:
General capabilities: dr1 delay hardware reorderedopaque flush
Threading capabilities: none
Supported hardware devices: cuda cuda
Supported pixel formats: yuv420p nv12 p010le yuv444p p016le
yuv444p10msble yuv444p16le bgr0 bgra rgb0 rgba x2rgb10le x2bgr10le gbrp
gbrp10msble gbrp16le cuda
av1_nvenc AVOptions:
-preset <int> E..V....... Set the encoding preset (from
0 to 18) (default p4)
default 0 E..V.......
slow 1 E..V....... hq 2 passes
medium 2 E..V....... hq 1 pass
Best regards.
