How to convert 3GP video for Android to view?

Question

I'm creating 3GP videos with the Android - however, when the 3GP files are posted on a site, the same Android phone cannot view it back. (The file works on the iPhone).

What is right way to encode/resize the 3GP video so that the video player on Android can play it back?

Thanks

Answer 1

Solved this by converting it to MP4 and then recompiling the Nginx server to have the MP4 streaming module. By default, Nginx mimetype was set to [application/octet-stream] instead of [video/mp4].

This seemingly was resolved on Froyo handsets - at least, when a 3gp file is opened in a browser window using http, and not rtsp, the video plays fine. On 2.1 it doesn't.

To make mp4 video streamable, you should change it's 'atom' byte order. I'm using qt-faststart tool from ffmpeg package for this.

This tool changes the order of some meta-data inside mp4 container and as result allows to perform video "streaming" over HTTP.
