Getting Multi Bitrate MP4 on output

[kotso]

Hello,

I'm trying to implement process that would give me multi bit-rate mp4 file on output. (each stream should have different resolution also)

I could create each resolution/bit-rate version first and merge that works fine, but I think doing it under single trans-coding process will be more correct but struggling with filters and maps.

If anyone has sample, could you please share it?
