AFAICT, ffmpeg and gstreamer decode will automatically scale each frame to the designated output resolution. Thus, if input has 100 frames in multiple resolutions and output is specified as NxM resolution, then all 100 frames in the output will be NxM resolution.

Can you describe a case where we need multi-resolution support?

now gstreamer add parse "videoscale" to make the output as single resolution, so no need multi-res md5 support, close it
