I'm trying to retrieve playback video from onvif device with time range.
I implement code to get replay uri according to
Retrieving Recorded Video from an ONVIF Device[^]
1. GetServices
2. GetRecordingSummary
3. FindRecordings
4. GetRecordingSearchResults
5. GetReplayUri
Then, I got replyUri from Onvif Camera(Axis,Hikvision) that provide the whole record (startDate to CurrentDate).
Now, I try to take the playback video (with specified date range).
According to XProtect VMS: Manage video playback[^]
we can manage playback video using vlc wrapper.
For me, vlc wrapper can not manage even rate speed(vlcplayer.Rate *= 2) of that uri video.

If you have any advice, please share me.
