Media Player and .mp4 files?

chilliwilli · #1 (**permalink**) 02-20-2009, 11:54 AM

Ok guys, been digging for quite sometime with no luck. I just converted some DVD's using Handbrake. Converted to .mp4 files at 480xdefault. all files are around half a gig to a gig. What is boggling me is why do some play fine and others will jsut play the audio of the movie through windows media player. With handbrake all movies were converted to mp4 files, of course quicktime and itunes see all movies fine and plays fine as far as that goes my TP will see all the movies, see the size, properties everything its jsut that some play fine and other will only output audio with NO video. Is there another player I could use? or is it a codec issue with WMP that I can update?

Thanks for any and all help anyone can give me. This is driving me insane!

MP4 is a container. The video could be encoded many ways inside it - H.264, XVID, etc. The encoding must be H.264 for it to work correctly in WMP, unless I'm mistaken.

I believe in handbrake they are all defaulted to ffmpeg. that has always seemed to work i nthe past as well.

Can Handbrake convert the videos to 3gp format? That will probably work better on your device, also some divices can play flv format.

ffmpeg is a program, not a format. It can be used to convert to many codecs.

Okay maybe I should just stick with the general question: why does WMP play some .mp4 and not others? does anyone know of a more robust player possibly freeware or sharware is fine too?

It plays all of my mp4 files just fine. I download my files in mp4 format so there is no converting done on my end. Works great

Download a program called MediaCoder. It is developed by a few Chinese dudes, but is all in English. It as all of the demux/muxing codecs included for transmuxing pretty much media format. It even has a setup wizard when you start it and you can select device profiles (choose a device that is VGA) and it will convert any media file into the correct container and codec type (you are shooting for x.264 for video and AAC for audio).

Like someone else said, .mp4 is a container type and can be used for multiple codecs, both audio and video. What is most likely happening is that your current conver isn't properly transmuxing (converting) the video into the x.264 codec and is instead resizing a XvID or DIVX

encoded file and putting it into the .mp4 container.

As an alternate, you can use CorePlayer to play these files on your phone.
