I try to open the link on browser and it looks fine, while using MJPEG class is not working i try to locate where the condition ends this part B4X: If startframe > -1 And endframe > -1 Then returns False, that why it did not continue the preview

For both variables are always greater than -1 if there is a valid MJPEG file. You need to stream each frame till the current frame is equal to the variable endframe. I think it more efficient to use a added currentframe variable which is increased in every loop as a counter and will be used to stream the image in a do while loop. Upvote 0
