I recently posted my first attempt at replacing Flash (FlowPlayer) audio/video streaming with HTML5 streaming audio/video. Here is that page:

I have inconsistent previews of the various videos. Most are working normally, however some simply have a black screen as the preview. What is the source of this inconsistency? How do I correct this such at every video has a proper preview, any preview relevant but just not a total black image?

Thanks,

Kurt

Looks like the thumbnail just pulls the first frame of video - in some cases its a black frame.

You could modify the HTML code to show a specific poster image instead of the first frame of video to gain more control.

Great news! thanks. I would love to see the complete list of Attributes to learn what other tricks I may use. It was confusing that coding a title for the video was a waste of time. Using the HTML "title" it is never utilized. I don't understand why that is. I took all those references out of the code since they had no effect on what is rendered.

I'll give the Attribute a try and see if it works.

Regards,

Kurt

Not all that familiar with it, but "title" might be geared towards HTML accessibility (similar to 'alt text').
