[XviD-devel] Fwd: How to use the xvid_encrew.c

[Michael Militzer]

Hi,

the URL I posted has 18 standard yuv sequences available for download. The
file ending is not YUV but that's nothing to worry about. You can rename to
.yuv if you want (but that's not needed). Try e.g. this file:

http://meru.cecs.missouri.edu/free_download/videos/foreman_qcif

That's the well-known Foreman sequence at QCIF (176x144) resolution.

Regards,
Michael
