easy way to repack or demux/remux mp4 video without re-encoding

[Drebin]

i have a few MP4 files that do not play on my media devices i use stream content to tv, looking at the specs for the videos that i have been issues with it seems the problem points to writing library.

its simple to re-encode these with handbrake using the same format for video and audio and they will play on anything however i am wondering if there is easy way around this problem using other software that will make the mp4's compatible without a full re-encode?

any suggestions are much appreciated!

Try remux with mymp4boxgui or yamb, open the mp4 and make a new mp4 under multiplexing.

Or ffmpeg, ffmpeg -i video.mp4 -acodec copy -vcodec copy newvideo.mp4.


And does your media device support hd material(1280x720pixels)?

thanks i will give it a go!

my pc/laptop can handle playing and streaming full hd content no problems, its via a wired network so no problems with bandwidth speed. definately a container/format issue with the files in question as i have no problem streaming higher quality 1080p mp4s with specs like these...
