Comment (by Philius):
I did a
git pull -a
Then I downloaded the patches into a "patches" sibling directory and then
did
cat ../patches/*.patch | git-am
and re-ran configure.
I got the following error
ERROR: libx264 version must be >= 0.115.
I had a look at wheezy's repos and libx264 only goes up to 112, so it's a
no-go on Debian for the
moment.
I recorded the "problem" video using cheese - about 49 minutes @ 640x480,
video 30Hz
, audio 1 channel @ 44,100KHz, which came to 2.5GB.
I ended up splitting the conversion run into 30 mins + 19 mins and joining
the two avi's, dropping the
audio and rotating 180 degrees - I recorded myself solving a sudoku puzzle
in real-time to try to
capture the stream-of-consciousness involved, so small flurries of
activity in a mostly static frame.
The video info claims 30fps but it looks more like 2-3 fps which may be
because of disk/cpu
bottle-necking + small variations in lighting conditions affecting overall
illumination, if that helps.
The resulting AVIs have visible tinges of green(top) + pink(bottom) which
aren't present in the
original, with -sameq(246MB) and hqdn(73MB).
