mp4 encoding used by Google Video?

Question

I have an HTC Touch HD on which mp4 videos downloaded from Google Video play the best, both in terms of video and audio quality. So I am wondering which settings exactly Google Video uses to encode videos into mp4, so that I can replicate it for videos not available on Google Video. A tool which reads an mp4 file and tells you all the encoding information would be perfect or if you know a official website that describes Google Video's mp4 format, then even better.

I am looking for the following information:

Video Encoding

• video resolution (e.g. 480x640)
• frames per second (e.g. 25 fps)
• bitrate (e.g. 1Mbit/s)
• codec (e.g. H.264)

Audio Encoding

• sample rate (e.g. 44100 Hz)
• bitrate (e.g. 128Kbit/s)
• audio channels (e.g. 2)
• codec (e.g. AAC)

I hope anyone can help even though this is not necessarily programming related. Thanks!

Most any video demuxer can give you this information. AVIDemux, mplayer, and VLC for example, all have an information mode that dumps the specifics of a video file, including some codec settings.
