mpeg video on iriver H10 20GB

<< < (2/2)

undergroundx:
uhh man i dont get why this is doing this makes no sense. This is what i typed in

 ffmpeg -i ConvertTube_com.mpg -s 160x128 -vcodec mpeg2video -b 200k -ab 192k -ac 2 -ar 44100 thevideo.mpeg

where it says thevideo.mpeg that is where i renamed it like you said.

ConvertTube_com.mpg: Unknown format
thats the error i get.

i also tried this using the acodec

ffmpeg -i ConvertTube_com.mpg -s 160x128 -vcodec mpeg2video -b 200k -ab 192k -ac 2 -ar 44100 -acodec -mp3 themovie.mpeg

still no luck any ideas why?

cool_walking_:
Are you sure ConvertTube_com.mpg is not corrupt (i.e. can you play it on your computer)?

Otherwise, there may be something wrong with the way ffmpeg is set up on your computer, and I'm not even going to start to troubleshoot that since I've never even used ffmpeg.  However, the following mencoder (comes with mplayer) command has handled every file I've thrown at it:

mencoder -of mpeg -oac lavc -lavcopts acodec=mp3:abitrate=192 -af resample=44100:0:0 -ovc lavc -lavcopts vcodec=mpeg2video:vbitrate=200 -vf scale,harddup -ofps 20 -zoom -xy 160 ConvertTube_com.mpg -o thevideo.mpg

Most options there are equivalent to those in the ffmpeg command, but there's a new one:
-ofps 20 means the output file will be at 20 frames per second.  You can probably omit this if you want, I only use it (with a value of 12) because the iPod 5G is too slow to run at fullscreen faster than 12 FPS.

and a slightly different one:
-zoom -xy 160 means the video will be scaled to 160 pixels wide (height is automatically calculated).
