I suspect colorspace, so try explicitly set on input (or convert)
colorspace maybe... There is a lot of options -vf, -pix_fmt, -sws_flags
etc. you can test - find them on ffmpeg wiki here
https://trac.ffmpeg.org/wiki/colorspace
Finally, managed to get it working!
ffmpeg \
-hwaccel vaapi -hwaccel_output_format vaapi \
-bsf:v
h264_metadata=colour_primaries=1:transfer_characteristics=1:matrix_coefficients=1
-i rtmp://localhost/stream1 \
-hwaccel vaapi -hwaccel_output_format vaapi \
-bsf:v
h264_metadata=colour_primaries=1:transfer_characteristics=1:matrix_coefficients=1
\
-i rtmp://localhost/stream2 \
-filter_complex "[0:v][1:v]overlay_vaapi=w=500" \
-c:v h264_vaapi -global_quality 25 -g 50 -r 25 -an test.mkv
The output looks normal.
Thank you very much BloodMan, for pointing me in the right direction.
