EasyCVR is a streaming media video service integration platform integrating video network sharing, storage, streaming media forwarding, video transcoding, video cloud, intelligent analysis and unification. Recently, we have been developing the EasyCVR platform about the problem of GB28181 device access. After we connected the device to EasyCVR platform through national standard protocol, the device was successfully registered, but the platform side could not get the channel of the device for video playback.
Here, we tested the trial version of EasyCVR. The default authorization of trial version is 200 channels in 45 days. In the device registration message, it will judge whether the number of channels of the device exceeds the number of remaining authorized channels. If the number of authorized channels is insufficient, the device discards the channel information without saving it.
At present, EasyCVR authorization is authorized when playing, so it can not be authorized during device registration. No matter how many remaining authorized channels, device channel information can be displayed normally, but the video exceeding the authorized channels cannot be played.
Therefore, it can be determined that this is related to the number of authorized video channels of the trial version. We need to annotate the relevant decision logic so that all the authorized channels of the trial version can play normally, so as to solve the problem.
After modification, all video channels can play normally, as shown in the figure:
The EasyCVR has been stable and reliable from the initial development to the present, which has not experienced too many twists and turns, mainly because the TSINGSEE Qingxi Video team has rich experience in the streaming media platform development industry, and many problems can be quickly responded to and solved. In addition, different from other video platforms, EasyCVR can support video analysis data and multi-source data fusion, mining value data through intelligent analysis algorithm, which is also an important feature of EasyCVR.
If you are interested in the EasyCVR platform, welcome to download deployment, actual test, during the test can be free to call the secondary development interface, welcome to understand.
