tired of hacking your script, please add h264 640x480 level3 low complex profile to your export list

Reported by: anonymous Owned by: Isaac Richards
Priority: minor Milestone: unknown
Component: perl / nuvexport Version: 0.20
Severity: medium Keywords: ipod h264 x640
Cc: Ticket locked: no


I have been hacking your version 3 svn of nuvexport for almost 10 months to get various added arguments added to allow ffmpeg to output certain types of files. The one I would really like to see allocated in your next release is ipod h.264 640x480 support.

Here is the ffmpeg code that produces acceptable Ipod video aswell currently the UUID can be patched using a program called atomicparsley

ffmpeg -i INPUT -acodec aac -ab 160k -s WIDTHxHEIGHT -vcodec h264 -b BIT_RATE -flags +loop -cmp +chroma -partitions +parti4x4+partp4x4+partp8x8+partb8x8 -me umh -subq 7 -trellis 2 -refs 1 -coder 0 -me_range 16 -g 300 -keyint_min 25 -sc_threshold 40 -i_qfactor 0.71 -bt BIT_RATE -maxrate 10M -bufsize 10M -rc_eq 'blurCplx(1-qComp)' -qcomp 0.6 -qmin 10 -qmax 51 -qdiff 4 -level 30 -aspect WIDTH:HEIGHT OUTPUT.mp4

please let me know if and when this functionality can be added as soon as its done I am deleting my hacked scripts and just upload yours.

feature request without a patch, and for an ancient version of nuvexport.

the current mp4 exporter works fine for ipod video, I use it all the time.
