[Xerte-dev] Re: Video playback quality in html5 LOs.

[Julian Tenney]

Yes, that's why an flv snuck through: the door is open to flv for those still using the flash runtime. But we should get to a point when Flash is dead to us soon.

If you upload high quality video, it will play back high quality as things stand. If you upload poor quality, it doesn't matter how you re-encode it, it will remain poor quality.

If you automagically encode it to different formats, you have to make some big assumptions and there are trade-offs between quality and bandwidth.

That's an interesting expression. I hadn't come across that before.


Is there a standard/definition for what can be in the LO's data.xml?




We had the issue that the user uploaded a video in flv format, which didn't playback. Transcoding it to .mp4 fixed the issue.


Can the editor restrict the file format(s) uploaded at all?

I presume the non-HTML5 variant of XOT required FLV videos?
