I may have misunderstand something...
I try to encode, and modified the CODA_MAX_FRAME_SIZE to 0x500000 just to see.
And here is the trace-cmd :
$> trace-cmd record -e v4l2* v4l2-ctl -d1 --stream-out-mmap
--stream-mmap --stream-to x.raw
[...]
$> trace-cmd report -R | grep bytesused

And the bytesused is 5MB which corresponds to the 0x500000...
How is the encoder supposed to work precisely ? I missed something...
Thanks,
JM
