Support for trick mode in custom roVideoplayer

I want to provide trick mode support in my app where I have a custom video player. Generally, roVideoScreen by default support trick mode if one feeds the bif urls to it.

I have successfully created the bif files but I have difficulty in reading it and showing the images in my custom videoplayer when I do FF/RWD .

I created the bif files using ffmpeg and biftool.

How to make use of the bif file in the custom videoplayer to provide trick mode support?

Thanks in advance.

You first need to study the SDK documentation
And the examples. There is an example of
How to use roimagecanvas with rovideoplayer
Once you have mastered the examples you will
Have discovered how to put any image on your
Canvas including your track bar which you
Can create the png or preferably jpg files with
A multitude of freeware paint programs out there

As far as a tracking algorithm , that is another ball game !
Your next battle will be to capture every message by rovideoplayer
To discover how it works and the problems you may encounter
And how you should deal with them

roVideoPlayer does not have native support for BIF files. You would have to build your own solution in BrightScript.

I had created my player with custom seek bar and other functionality. I am able to play the videos as well.
i had the bif files created in the server but my difficulty is in reading the bif files and fetching the images for display.

The rourltransfer object gettofile. Or the asynchronous version will
Read your file from the server to the Roku temp directory. You can load it
From there i don't use bif format not even sure if it is supported. But png
And jpg I read and load without a problem from my server

Re: Support for trick mode in custom roVideoplayer

I wrote a small app to display videos and images. When video runs overlay images are displayed. The images I want to display are jpg/png. But sometimes images are not displayed even if the video runs without any problem. When I use teraterm the log shows that images are already displayed. Initially I thought it could be the layer problem. But when I check that too, I found no problem. Images are displayed after the video is started. Can you give me suggestions on this issue. It would be highly appreciated.

Thanks in Advance
