We are creating the thumbnail rendition(638x638) for video asset using asset.addrendition(name, inputstream, mimetype) dam API.
External image will be read and add it as rendition for video asset. For few video assets, we can able to view this thumbnail by double clicking the rendition and open it in different tab.
For few video assets, we can't able to view it by double clicking that rendition. No error is appeared in the logs
Please provide your inputs to find the solution for this issue.
Thanks in advance !!
Please help us with following:
Are you using touch UI or classic one?
Videos for which you don't see thumbnails, does it have some other auto generated thumbnails? If yes, share the same.
Is the mimetype of these particular videos different from the ones for which you can view the thumbnail ?
