[FFmpeg-user] MJPEG encoder large memory allocation issue

Hi Carl,

Error is :
[mjpeg @ 0x557c0] Failed to allocate packet of size 144935000

As per my understanding the units is bytes.
So 144935000 bytes = 138 MB and not 14 MB.

yuvj422p means 16 bit per pixel, while these are less
than 12M, I don't think an allocation of 14M is
completely unexpected or do you disagree?
