Encoding video for mp4 player

i want to encode videos to be opened in my new mp4 player

it came preloaded with an example videoclip and it has cam built in. it can play the original clip and stuff captured by the cam

when i try to encode something else with ffmpeg for it it does not work. the player shows error message and refuses to play the file

i tried various ffmpeg options

it came bundled with some converter.exe but it is for windows

computer (linux with ffmpeg) plays and converts successfully the clip and the cam captures




preloaded clip download (18 MB) (sorry if copyrights or something)

cam sample download (12 MB)

ffmpeg output on converting the original video to something else

preloaded clip

Re: Encoding video for mp4 player

Why are you converting the files to WMV? The first one is showing mpeg4 video and mpeg2 audio in an AVI container. WMV (in this case) is msmpeg4v2 (a MS specific format) and mpeg3. Just to test, encode a test video with:

ffmpeg -i <your_video> -vcodec mpeg4 -acodec mp2 output.avi

It's going to look like crap, but it will allow you to see if it works.

Alternatively you can encode with mjpeg as your video codec and  adpcm_ms as your audio codec. You could probably use libmp3lame for audio. And, if FAAC from the repos wasn't broken, you could use m4a. If you care about that, the fix is already known.

Renaming the files isn't going to work unless you're using something like MPlayer or VLC. mp4 and AVI are much different containers.

What did you try exactly?

Re: Encoding video for mp4 player

I'd still like to try a bit more if you don't mind.

What's the player that you're using?

Re: Encoding video for mp4 player

Try something like this with ffmpeg.   The mpg is a vcd clip I had laying around.  The  IAmLive.avi (from your player) is a XVID encoded avi with mp2 sound. 

 ffmpeg -i dia01.mpg -vcodec mpeg4 -b 700k -s 320x240 -acodec mp2 -ar 44100 -ab 128k -vtag XVID ~/work/test.avi

Re: Encoding video for mp4 player

I use mvPod to convert xvid, mpg etc movies for my iphone, perfect quality.
http://mvpod.sourceforge.net
if you use itunes file ending must be .mp4

Re: Encoding video for mp4 player

Maybe, you could look to a small project I have:
http://www.4nakama.net/download/encX264.sh

The bash script came with cool options for .mp4...
