 Please update implementation or docs for https://ffmpeg.org/ffmpeg-
 codecs.html#libopenh264 :

 It is a bit hard to find available openh264 params, but following
 https://github.com/cisco/openh264/blob/master/testbin/welsenc.cfg it seems
 there are some interesting ones available `ComplexityMode`, `RCMode`,
 `MaxQp`, `MinQp` and few more.

 Some other encoders have `***-params` available, so I propose
 `openh264-params` to be able to pass not yet implemented ones...

 Current doc mentions `slice_mode`, however seems deprecated:

 ffmpeg ... -c:v libopenh264 -slice_mode fixed ...

 [libopenh264enc @ 00000203cc219500] The "slice_mode" option is deprecated:
 set slice mode, use slices/max_nal_size
