Description

Hi,

yesterday's head version of mplayer extracts a wrong framerate from the attached .3GP file:

$ mplayer -identify -frames 1 converterror2/1682309563324095.3gp

mplayer changed to use -demuxer lavf as default for mov files
workaround : use -demuxer mov

you can report this to ffmpeg team, as long as you test with ffmpeg svn first. you can find their bug tracker at ​http://roundup.mplayerhq.hu
