Re: When Recording RVCamera.onNewImage Event Always Set at 21.5 FramePerSecond

Not sure processing this event takes too much time because the onNewImage event is called about 21 FPS no mater the FramePerSecond. I have tried it with FPS = 2, 3 and 15 and onNewImage is still called roughly 21 times per second.

Thanks in advance.

Re: When Recording RVCamera.onNewImage Event Always Set at 21.5 FramePerSecond

More Information: I am using DeviceType := rvdtUserData to create video from supplied bitmaps. The problem is when you set framePerSecond > 21. For example, setting FramePerSecond to 30 FPS creates a video file where the images change only 21 times a second so the effective FPS is 21 vs. 30. Images ...

When Recording RVCamera.onNewImage Event Always Set at 21.5 FramePerSecond

When using the RVCamRecorder component, the connected RVCamera.onNewImage event is always called at 21.5 frames per second regardless of the RVCamera.FramePerSecond setting. The resultant image contains the correct number of frames as specified by RVCamera.FramePerSecond but onNewImage is always cal...

Video Created has Blank (black) for 1st Frame

Writing from 1) a camera or 2) user supplied images the first frame of all videos created is always blank (black). Thanks for implementing the feature to create video from user supplied images.

Problem using new DeviceType := rvdtUserData

Hi Sergey, Attached please find some sample code that demonstrates the problem with RVMedia. I am using DeviceType := rvdtUserData to write my own images to a video file. A file is written but the OnNewImage event of the MRVCamera is never called. I get a video with blank (black) images. Also fails ...

Re: Does Camera Search reveal cameras you don't support ?

To be clear, cameras such as Amcrest that you do not support, DO show up in the Camera Search Demo if they produce MJPEG/H.264 steams ?

Can your software broadcast images to the internet ? Or do I use INDY 10 TidHttpServer ?

Does Camera Search reveal cameras you don't support ?

1) Does your Camera Search enumerate cameras you don't support (Like Samsung)? How do you recognize cameras ?

2) Is there a limited range of IP Addresses devoted to IP Cameras? It would take hours to search: 10.x.x.x or 192.168.x.x ?

Thanks,

John
