Add a publication. In the publication in the download materials section, select and test:
1. Video - the video does not have a picture, three dots are shown, when adding material, it is written - wait while the file is being converted. At the same time, there are no buttons to insert video into the text.
2. Audio - the file is being converted.
3. Audio and video recording - added.
As a result, more than an hour passes - the material has not been published, it is being written - audio and video is converted, wait, only then the material will be published. What should we do - what could be the problem? At the same time, all materials are fully uploaded to the server, but not converted.
