I have installed the YouTube ECL Provider plugin: https://www.sdltridionworld.com/community/2011_extensions/youtube_ecl_provider.aspx
I followed all the steps, copied files, configured XML with folders, etc.. and I managed to load videos of a YouTube account in Tridion. Also, I created a multimedia type for ECL and I have given permission to a Schema to allow this multimedia type:
When I create a new Component with the Schema and I related it with a Video from YouTube provider, the publication crashes with this error:
Sequence contains no matching element
If I publish the same Component without the video, the publication is success.
How can I publish ECL videos for implement my jspx's?
