Does Kaltura CE support converting iPhone 4S video 1080p videos? I seem to be able to upload other mov files and successfully convert (640 width x 480 height) samples I grabbed from the web, but 1920x1080 videos taken with an iPhone, transferred to a computer, and uploaded through the web interface Error after trying to convert.

The /opt/kaltura/web/content/entry/data/4/267 folder contains the uploaded mov file, so I believe the upload part is working.

Attaching the log file.

Also, I tried enabling every Settings -> Transcoding Settings and restarting the apache server to see if that would fix things. It did not.

Hi,

Seems like the error line that might be relevant is this:
2012-05-23 11:51:14 [127.0.0.1] [1710592700] [API] [KDLWrap->generateTargetFlavors] NOTICE: ...T-->flag(0),CON(f:flv), VID(f:vp6,br:3200,1280x720,fr:30,g:60,rt:90), AUD(f:mp3,br:192,ch:2,sa:44100),WRNS(video=>0=>2112,ffmpeg#The transcoder (ffmpeg) can not handle this content.,1=>2112,ffmpeg-aux#The transcoder (ffmpeg-aux) can not handle this content.),TRNS(2=>tr:mencoder,cmd: __inFileName__ -of lavf -lavfopts format=flv -ofps 30 -ovc lavc -lavcopts vcodec=flv:vbitrate=4000:mbd=2:mv0:trell:v4mv:cbp:last_pred=3:keyint=60 -vf harddup,scale=1280:720,rotate=1 -oac mp3lame -lameopts abr:br=192 -srate 44100 -o __outFileName__)

Will be helpful if you can upload the video you tried to this thread.

Here's the video. I had to rename the file extension to txt to bypass restrictions on upload. It should be renamed to .mov.

I was able to get Kaltura to ingest iphone 1080p videos and successfully convert them to the flv format used by Kaltura for the web. The problem was that the Community Edition converters don't work right out of the box on some 64 bit operating systems.

Ubuntu Instructions (may have to adjust for CentOS):
/opt/kaltura/bin/mencoder-dir$ sudo apt-get-install mencoder
/opt/kaltura/bin/mencoder-dir$ sudo mv mencoder mencoder_original
/opt/kaltura/bin/mencoder-dir$ which mencoder (to find out where installed)
/opt/kaltura/bin/mencoder-dir$ sudo ln -s /usr/bin/mencoder mencoder

Same for ffmpeg in /opt/kaltura/bin/ffmpeg-0.6-dir and /opt/kaltura/bin/ffmpeg-0.6-dir/lib.
