Opencv, odroid, onvif, eclipse - video stream

Есть 2 задачи по екслипсоподоьной прошивке для камеры:

1. Did you ever have OpenCv report message Invalid UE golomb code when reading FFMPEG stream, and do you know about solution ?

I can provide access to the lap top by teamviewer..I have eclipse opened  with the project and program running in console toward camera attached

This is my camera stream rtsp://admin:[email protected]:554/11

Works fine from vlc player on the pc

Found this link

https://github.com/opencv/opencv/issues/9739

cv::cudacodec::VideoReader unable to Play rtsp stream  · Issue #9739 · opencv/opencv

Maybe it is the issue

You should check if the codec and pixel format of your stream (as shown in vlc) are they supported in the InputMediaStream_FFMPEG::open method.

What i found out in my case was that while vlc detected the pixel format of stream as YUV420P, ffmpeg detected it as YUVJ420P so i made the below mentioned change here

case AV_PIX_FMT_YUV420P: 

case AV_PIX_FMT_YUVJ420P:

    *chroma_format = ::VideoChromaFormat_YUV420;

     break;

As far as I can see for OpenCv capture extra configuration needed when FFMPEG stream

2.  onvif:

Also need onvif control:

It is to be able to adjust contrast, light condition etc. from remote linux in the camera using onvif

I have a filter in front of lens removing reflections in night time...It demands that I can adjust light, and contrast etc for daylight/nightlight

Since recognition engine is in linux I need to do it based on what I see or not see

automatically..But I just need you to implement the feature to be able to over onvif

Исходники приложил.

Для тестов предоставлю ПК по teamviewer с развернутым проектом и подключенным оборудованием.

If it is easier to make camera give mjpeg stream without described issue instead of FFMPEG - that is ok solution for me
