Testing RVCamera - Video blurred

[ya_vanka]

RVMedia supports GStreamer 0.1, not 1.0:

I've read it, but can you explain why? 0.1 is soooooo outdated...

[ya_vanka]

And do you have any ideas how to solve ffmpeg problem?

[Sergey Tkachenko]

There are several RVCamera.FFMpegProperty properties that could help.
First, I recommend assigning MaxDelay = 500 000.

[ya_vanka]

Can't find MaxDelay property in RVCamera.FFMpegProperty

[ya_vanka]

And is it possible to pass parameters to ffmpeg?

For example I would like to pass -an and -fast parameters (ffplay.exe -an -fast rtsp://:8554/stream.sdp)

[Sergey Tkachenko]

Current version of RVMedia does not allow to pass arbitrary parameters to FFmpeg, only parameters listed in RVCamera.FFMpegProperty.

MaxDelay must be the second property listed in RVCamera.FFMpegProperty in the Object Inspector.

MaxDelay must be the second property listed in RVCamera.FFMpegProperty in the Object Inspector.

But it isn't there:

What version of RVMedia do you use? New version has much more properties there.

I used version 6.1

Tried version 7, but cant get video stream. I use VideoRecorder project.
Changed in unit SampleCamList the following line (20):

'alias=CAM 1|' + 'url=rtsp://127.0.0.1:8554/stream.sdp|' + 'host=|' + 'port=|' + 'login=|' +

But I get only message: Video stream error.

What has changed in version 7?
Why can't I get the same video stream that works in 6.1?

[Sergey Tkachenko]

Do you have FFmpeg available for the application?

I used version 6.1

Tried version 7, but cant get video stream. I use VideoRecorder project.
Changed in unit SampleCamList the following line (20):

'alias=CAM 1|' + 'url=rtsp://127.0.0.1:8554/stream.sdp|' + 'host=|' + 'port=|' + 'login=|' +

But I get only message: Video stream error.

What has changed in version 7?
Why can't I get the same video stream that works in 6.1?

[ya_vanka]

Yes, I do.
I even placed dlls in the same folder with apllication.

[Sergey Tkachenko]

Probably, FFmpeg codec does not like some options specified in RVCamera.FFMpegProperty.
Try assigning RTSPTransport = [rvpeTCP,rvpeUDP]

In the next update, we will add a property to turn off all FFMpegProperty options.

[ya_vanka]

assigning RTSPTransport = [rvpeTCP,rvpeUDP]

Thanks, this helped!

But why these values are not set by default?

[Sergey Tkachenko]

We changed this default value in our working version, so it will be changed in the next update.

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. Why is this not working on the rv-ffmpeg multi camera view example?

Thanks,
