Can't play "dash" video-codec.

Mikhail

Hello All!

I have issue: I can't play video, which downloaded from youtube(mp4-file). Video succesfully added to Isadora Library, but when i start to play it, only black screen showed, and audio track plays at 2x speed, although speed is 1.0.

Is it possible to open such video?

Thanks for your advice!

Here is source media, and bellow is mediaInfo:

I think its the .avc codec thats the issue. I would suggest changing it to something else.

Mikhail

Skulpture , yes, i think so.

Maybe it is possible to correct something in isadora to work with that codec? It would be great!

I don't think its quite as simple as that.

Codecs are funny things and Mark picks the codecs that work the best with Isadora. Some codecs are not suitable for live performance.
