Chrome won't play m4v right away

[mnez]

Hi

I am having an issue with m4v movies and Chrome and was wondering if
there were any suggestions?

This was my process/settings:
My original movie settings (.mov): 640x360, Animation, 16-bit integer
stereo, 29.97fps,
data size: 1.28 gb, datarate: 118.50 mbits/s, duration 1:32

I then exported a m4v through QT player 7 (export for web) and only
selected desktop (don't need iPhone). There is no option for changing
the export settings when it's "export for web". The final output was
(.m4v): 640x360, H.264, AAC stereo, 44.1, 29.97fps,
data size: 22.98 mb, datarate: 2082.19 kbits/s, duration 1:32.

Problem: When uploaded, the movie plays right away and is fine in IE,
Firefox, and Safari. In CHROME it will not play at first (shows a gray
box). You have to leave it up and after a minute or more, then it will
play. Is there something that should be switched so it will play in
Chrome as soon as you click on the webpage?

Any suggestions would be greatly appreciated. Thank you.

Chrome seems to require about 80% or possibly all of it to download before it starts playing. This seems to change with each update though and seems to affect the M4V format with H.264 video. This may be another reason why they plan to drop it in future.

I'm curious, which version of IE did you say worked?

For other browsers, I tend to assume the latest version or at least a recent version... But some people still use IE8 or even IE6. I ask as IE8 and before will use the Flash.

Google tends to recommend the WebM format for use on their browsers... They suggest you give the OGG (Theora,Vorbis) for older version of their browsers and Firefox 3.6 and the WebM (VP3,Vorbis) for the newer ones. Then H.264 for the others like Safari, iOS and IE.

I have not checked to see whether the latest versions of Chrome cope with the download of WebM format videos better than H.264 mp4 format.

With our current jPlayer demos, we recommend using M4V and OGV. Making 2 sets is enough to cover all browsers. WebM is a better video format than OGV, which is why they recommend the 3rd format so that the latest HTML5 browsers (Chrome,Firefox,Opera) and use that instead.
