I am able to transcode from
mov wmv avi
to
mp4 flv

but I cannot find working settings for 3gp - I was able to transcode 3gp to flv in the video module, but the same settings don't work for the other formats

output:

FFmpeg failed to transcode sample.3gp.
Reported errors

PHPVideoToolkit error: Execute error. It was not possible to encode "/var/www/[domain]-dev/sites/default/files/videos/original/sample.3gp" as FFmpeg returned an error. The error is with the audio codec of the input file. FFmpeg reports the error to be "Error while opening encoder for output stream #0:1 - maybe incorrect parameters such as bit_rate, rate, width or height".

also, I am able to transcode the same sample.3gp file with ffmpeg on the command line, and the transcoded test_aac.mp4 file is fine:

The error is 'Too many bits per frame requested' for aac. You did not specify an audio bit rate, so it takes the bit rate of the input, which is 46 kb/s. This appears to be invalid for aac. So edit your preset and specify a specific audio bit rate.

thanks for pointing that out

from the command line I set -ar 44100

so in my presets > Advanced Audio Settings I set Audio sample rate to 44100

worked like a charm

I had problems with this aspect of the error "width or height not divisible by 2" when trying to convert from or to 3gp or 3g2 , this is the code i used and now is working:

(in this case is specified a given height of 720 pixels ..)

scale="'trunc(720*iw/ih/2)*2):720'"
