Hi i have a avi file that is 320x240 in resolution and 100mb in size. My goal is to convert it so that it will play on my little brothers cell phone after some googling i found the below site the only problem is that it dosn't seem to work for me ffmpeg complains about a missing codec and the site says
| Quote: |
Get the latest version of ffmpeg, look at ffmpeg/libavcodec/amr.c and follow the instructions in this file to enable amr/3gp support. |
but i can't find any such file
below is the output ffmpeg gives:
| Code: | fmpeg -i input.avi -s qcif -r 12 -ac 1 -ar 8000 -b 30 -ab 12 -t 60 foo.3gp
