In-software credit is OK also. About dialog states:
"This software uses portion of FFmpeg, a good video library. <link>FFmpeg
information</link>"
I don't know what the link does because that doesn't work, but I assume that it
brings you to the LGPLv2.1, which would be fine then. Might be nice if they
mentioned the LGPL here, but the link + "information" is enough ("license
information" would be better).
Strings for GPL verification:

looks like this file was encoded with (divx4/(old)xvid/opendivx) -> forcing

Xvid ratecontrol requires libavcodec compiled with Xvid support.

I checked add8x4, which is in h264_idct_sse2.asm, which should be enabled only
for CONFIG_GPL. Therefore, this is a GPL violation and is unresolved. The
x264_deblock operations also look like they're GPL.
