    So, I'm goofing off on my HTTP server and I have a couple random videos sitting in the folders and so I decided to try to play different ones to see what happens.

    Every .MOV file plays, but there's no audio.
    Almost every .WMV file plays, but there's never video.
    I can't play any .AVI file.

    This might be old news to some, but this is the first I've seen that you can actually play a .MOV.

    Technically MOV files are just shells holding a certain type of data compressed via a certain codec. Looks like the audio was recognized in one and the video in the other. This is why having an app like VLC would be great. It can play the majority of codecs out there.
    Similar things can happen on your pc and can be fixed by downloading a codec pack from the net.

    Interesting :)

    MOV (nowadays) is just an MP4 file. What happens if you rename one to .mp4 and access it? MP4 (as in my movie trailer thread in the video section) plays if you access it through the web browser.
    As for wmv, the audio format (wma) itself is supported by the droid, so from what it looks like is that the actual header of the video is ignored by the droid, and it just looks directly to the video and audio streams.

    The mov files, do they play progressively (as in play while downloading/streaming) ?

    All of the links I clicked forced me to download them first. I agree about the mp4 situation, but I would have thought the droid would have just trashed the link/file without even trying to play them.

    Now these .mov files I have were created on mediaconverter's website, from a youtube link. So its possible that their site just picks a default format, regardless of the format you choose.

    Sounds like the files are optimized for iPhone/iPod Touch mainly.

    The streaming app I am working on works on a similar principle, basically access the mp4 file using a direct http link, and it will play. To make this work on the iPod, no changes are needed, but for playback on a computer using quicktime, a special flag needs to be enabled in the video file header to make the file streaming-capable. I enabled this flag in my movie trailers as well. Based on feedback I received from some of the testers, it appears that for the Droid to play while downloading this flag needs to be set as well.

    Just like AVI's. That's why discussing these formats is a bit pointless unless you also mention the codecs involved.
