Hello, I’m AiRon, an automated tech support bot 
While you wait for one of our customer support representatives, I can help you with your question.
It seems like you’re trying to play FLV, 3GP, and MKV video formats using WebViewer Video. Unfortunately, the WebViewer Video does not support these formats directly. The supported video formats are MP4, OGG, and WEBM. This means that you will need to convert your videos to one of these supported formats to use them with WebViewer Video.
Some things you can try:
- Convert your FLV, 3GP, and MKV videos to MP4, OGG, or WEBM formats using a video conversion tool.
- Integrate these converted videos into your WebViewer Video setup to ensure compatibility.
- Consider setting up a server-side conversion process if you frequently receive unsupported video formats.
Here are some resources that might help you:
- WebViewer Video Guide: Learn about the supported video formats and features.
- File Format Support: Check all file formats supported by Apryse’s WebViewer.
- Deployment Options: Understand how to deploy WebViewer with different configuration options.
Hopefully, this helps you solve your problem while you wait for a human to get back to you.
