[Bug 410439] [NEW] Task: Make sure the 2 initial mp4 files work on ipod/iphone

[Fabricio Campos Zuardi]

Public bug reported:

The current recipes that we used for the hanoi mockup at and that are
listed on the wiki http://wiki.publicvideos.org/dev/transcoding_recipies
have not been tested on my ipod touch, we need to do that test before
rolling the massive transcoding batch just to make sure those files will
be useful not only for Safari users without the XiphQT plugin but for
iphone users too.

I know that those devices might not support some profiles of the h 2.64,
so it is better to doublecheck.

ok, in order to work on the ipod touch the videos must use the baseline
profile, here is what I tested and that worked fine:

ffmpeg -i intermediate.avi -an -pass 1 -vcodec libx264 \
-vpre hq \
-vpre libx264-baseline \
-b 650k \
-s 480x272 \
-f ipod \
-deinterlace \
-threads 0 \
-benchmark -y /dev/null

ffmpeg -i intermediate.avi \
-pass 2 \
-vcodec libx264 \
-vpre hq \
-vpre libx264-baseline \
-b 650k \
-s 480x272 \
-acodec libfaac -ab 128k -ar 44100 \
-deinterlace \
-threads 0 \
-benchmark -y 2009-05_00140_horse-eating-sky-field-480x272-hq-dp.mp4
