Some users reported that the EasyCVR v3.1 version was deployed on site, and the device was connected to the platform through the national standard GB28181 protocol, but the snapshot was not displayed on the page, so we are requested to assist in troubleshooting.
In response to user feedback, we immediately troubleshoot. After investigation, it is found that the video playback is normal, and the calling interface can also return the snapshot normally, as shown in the figure below:
After the follow-up investigation, it was found that because the front-end channels of the device management did not receive the snapshot url returned by the back-end, the snapshot screen was not displayed in the channel management of EasyCVR, and the technician immediately repaired it. The user deploys the modified new version on site, and the video snapshot has been displayed normally.
EasyCVR can gather, integrate, and centrally manage various scattered video resources in a complex network environment, and realize authentication management, on-demand access, network-wide distribution, and intelligent analysis of video resources. The platform has strong compatibility and high expansion, and can support multi-protocol and multi-type device access, including: national standard GB28181, RTMP, RTSP/Onvif, Hikvision Ehome, Hikvision SDK, Dahua SDK, Uniview SDK, etc. The platform can distribute video streams in RTMP, RTSP, HLS, HTTP-FLV, WS-FLV, WebRTC and other formats, and supports H.264/H.265 encoding.
Note: In the platform configuration, if the channel is set to non-on-demand mode, calling the snapshot interface will also result in failure to obtain snapshots.
