Problem with command line function converting video for sansa player

[Ulysses]

Hello,

I posted a reply to this http://ubuntuforums.org/showthread.php?t=892971&page=2 and realized (while I was at work, no less) that I should not have posted to a [SOLVED] thread, so here goes.

I did as instructed
Edited .bashrc to include the following lines:
# Command line function to convert video for sansa player
sansavideo() {
frame_per_second="23.98"
video_bit_rate="578k"

ffmpeg -i "$1" -r 29.97 -vcodec mpeg4 -b $video_bit_rate -ar 44100 -g 300 -s 320x240 -aspect 4:3 -ac 2 -f mp4 -y "$2"

}

I have the correct version of ffmpeg
I did this
ffmpeg -formats |grep aac
And received the proper result
D aac ADTS AAC
DEA aac
D A mpeg4aac

But when I put the command line in like this
sansavideo inputfilename.ext outputfilename.mp4

I get this error message
INPUT.avi: I/O error occured
Usually that means that input file is truncated and/or corrupted.

Though, I wonder now and am fain to admit that I did not think this before (I am as new as new can be at this and I really try, I really do), if when I executed the command line I did not use the terminal commands to navigate to the folder where the INPUTFILENAME.ext was located - and that the error message I received was a generic one that simply related to not being able to find the file

Please, any help would be appreciated. Sorry for posting in the wrong thread to begin with

You will first need to navigate to the directory where the input file is located or you can probably include it in your command such as:
sansavideo videos/originals/inputfilename.ext videos/outputs/outputfilename.mp4
Also, paste the output of:
ffmpeg -version

Woo hoo!!!!

Thanks for responding to me

This was the first chance I had to test it and it worked so well I think I might cry.

So that means I can now play video on my SansaView player.

Now, the fun lies in a couple more things
Write it up, mebbe, for someone else who wants to be able to make the most use out of this cool little player (got it as a factory refurbished for 70.00 CDN - 8GB with a slot for MicroSD that I can expand to)
And, what would be even better, is if mebbe someone could give me some tips on how to turn the command line into a little shell script that anyone could use and enjoy.

Thanks, again
