[Xerte-dev] Re: MP4 settings FormatFactory

Hi Inge,

Try "MP4 Explorer" (if you have a windows install) to examine the MP4 - http://mp4explorer.codeplex.com/

It will show you the location of the moov atom.

The moov section should be BEFORE the mdat section in the tree (see the screenshot) otherwise the MP4 must download first.

Also, Tom, I've tried the moovrelocator with a few mp4s that I had that have the moov at the end and it did indeed relocate the moov to the start and the file was still playable so it looks like it could be a good addition. It still needs testing with some more videos though before it goes live.

Possibly but would be good to know if it's down to case sensitivity or spaces first - Inge did you try my suggestions?

Would forcing all uploaded filenames to lowercase fix this?

Are the extensions uppercase by any chance? If you change to .mp4 instead of .MP4 and re-link the file does that solve the problem?
If that doesn't solve the problem what about removing any spaces from the filename and re-linking does that solve it?

I helped someone with this previously and I think it was one of those two scenarios that was causing the download link rather than playing the mp4. But have been extremely busy with other things and no time to investigate and see if a code tweak would avoid this.

Hi Julian,

I understand from Tom that you use FormatFactory for creating MP4 videos to use in Xerte.
I use FormatFactory also but I can't find the right settings :(
What settings do you use to create MP4 videos? Our MP4's are downloadable instead of streaming.

Bye,
Inge
