Re: RVMedia v7 - Recording Multiple local network cameras

Hi Sergey,

Currently, we use the same frame size/frame rate as the rtsp live streaming, that actually is h264 (1920x1080) at 25 FPS.

Regards,

Re: RVMedia v7 - Recording Multiple local network cameras

Hi all,

Continuing with the topic of improving the recording performance of multiple network cameras. Is there a way to setup the "-preset ultrafast" h264 codec option when using the TRVCamRecorder?

Thanks,

Re: RVMedia v7 - Recording Multiple local network cameras

It is RVMedia v7.1.1.

Is there any special configuration for the TRVCamRecorder in order to achive better results?

I read that we can dump the streaming directly to a file using a special codec called "vcopy". Is this possible using TRVCamRecorder?

Thanks,

RVMedia v7 - Recording Multiple local network cameras

Hi all, I'm having trouble recording several network cameras on h264 using rvmedia v7 with ffmpeg 4.2. The CPU consumption quickly reaches 100% and the quality of the recorded video is very low (loss of frames, blocking, etc.). I use a TRVCamera conected to a TRVCamRecorder for each local network ca...

Re: RVMedia and RTSP - Multiple local network cameras

Hello Sergey, Your test seems to work, but it is not the issue I'm dealing with. Can you try three local different cameras using the same instance of the program? For instance, you can setup several rtsp servers using the ffmpeg tool and test with it. Can you please do a new test and tell me why you...

Re: RVMedia and RTSP - Multiple local network cameras

Hi Sergey and panlab_mf, I downloaded your CamTest3 and compiled it with v6.1.1 And here is my findings: 1) Using ScaleMM and enabling optimize, the 3 cams become synchronized as shown in the attached image, while in your compiled exe there is variance. 2) Your exe always have one cam delaying the ...

Re: RVMedia and RTSP - Multiple local network cameras

If you use several cameras pointing to the same dynamic image like:
a) a move,
b) road traffic,
c) never end looping image.
it is easy to see how gradually the multiview's playback of each camera slowdown until the image jumps but still far away to be synchronized.

RVMedia and RTSP - Multiple local network cameras

Hi all, I'm testing the new RVMedia v7.1 ffmpeg demo project setting the "RVCamera.Latency = 0". If I run three instances of the program connecting three differents local network cameras, they work fine, it is, the image on all the programs are more or less synchronized along the time. But, if I set...

Re: RTSP H264 decoder generates image artifacts

Is there a chance than the RVMEdia 7.1 fix this issue? I think it is easy to reproduce, just use the ffmpeg demo project and configure it to connect two cameras with a regular changing image. Like this, http://92.154.56.150:8888/mjpg/video.mjpg You will see how gradually the playback slowdown. regar...

What I'm asking is how can I avoid that, playback two or more RTSP network cameras without latency in order to ...

Re: RTSP H264 decoder generates image artifacts

You can use this public trafic camera: rtsp://170.93.143.139/rtplive/470011e600ef003a004ee33696235daa and run FFMpeg multiview adding two times the same url. if you let the program running for a while (3 minutes or so) the image starts freezing and finally it stop playing in one of the viewer. At th...

Re: Testing RVCamera - Video blurred

Hi, I've tried the "test_ffmpeg" to understand what is happening to my project. But, this tool doesn't run with other dll's but the original deployed by you (see attached release note.txt). Any way, if I run several instances of this testing tool I can see no delay betwen each live streaming cameras...
