I tried with "-profile:v baseline -level 3.0" from here;
https://trac.ffmpeg.org/wiki/Encode/H.264#Compatibility
Unfortunately this didn't help.
As I don't find any documentation on this at
https://www.ffmpeg.org/ffmpeg-codecs.html#libx264_002c-libx264rgb
maybe there are more levels and variations ... where do I find more or
complete documentation on this?
With mediainfo I see, that I need "-profile:v constrained_baseline
-level 4.1":

This profile is only available with VAAPI encoder, see
libavcodec/vaapi_encode_h264.c
or amfenc encoder, see libavcodec/amfenc_h264.c
So I tried:
$ ~/Projects/ffmpeg/ffmpeg-git-20200211-amd64-static/ffmpeg -i
MVI_1324.MOV -c:a copy -c:v h264_vaapi -profile:v constrained_baseline

Unknown encoder 'h264_vaapi'
It seems, I use the wrong syntax. What is the correct syntax for
'h264_vaapi'?
