I am trying to convert .flv files downloaded from youtube.com / megavideo.com etc. into iPod compatible .mp4 movies using ffmpegX on OS X. Unfortunately every time I try and convert them it seems to work for about a minute and then suddenly produces an empty .flv file and says it is complete.
Here are the details of the conversion...
- From: flv
- Video: flv, yuv420p, 424x240
- Audio: mp3, 22050 Hz, stereo
- To: mp4
- Video: ffmpeg mpeg4, 432x240, 548 kbps, 23.976 fps, no crop
- Audio: aac, 48000 Hz, 96 kbps
And finally, this is the output after running the conversion and clicking the i button...
