RVMedia 2.1

RVMedia 2.1

RVMedia 2.1 has been released.
This is a free update for customers who ordered RVMedia before.

IP camera detection: more camera models are supported

The list of supported camera manufacturers is still the same: http://www.trichview.com/help-media/features.htm
However, the list of models available for detection is greatly expanded.
We optimized a camera searching, however, there are much more URLs to check now, so a search becomes slower.
To speed it up, we added a new parameter to SearchCamera method, allowing to narrow down search, if you know your camera model(s).
Also, you can increase the count of camera search threads.

GStreamer: more video file formats

In this update, RVMedia can play the following video files using GStreamer:
1) AVI file containing MPEG-4 Part 2 video stream
2) AVI file containing H.264 (i.e. MPEG-4 Part 10) video stream
3) MP4 (or QuickTime) file containing MPEG-4 Part 2 video stream
4) MP4 (or QuickTime) file containing H.264 (i.e. MPEG-4 Part 10) video stream.
Only the (1) was supported before.
Note: the main reason for using GStreamer is supporting H.264 video streams from cameras and using RTSP protocol. Playing video files is a by-product. RVMedia can play/send local video files without GStreamer (RVCamera.DeviceType=rvdtFile).

Desktop video source: multi-monitor support

If RVCamera.DeviceType=rvdtDesktop, the component supports multiple monitors. You can choose to send the whole desktop or the specified monitor (in addition to the modes of specifying a desktop rectangle or specific window).

Local web cameras: unique identifiers

In the mode DeviceType=rvdtWebCamera, in addition to VideoDeviceList[] property, we added a new property VideoDeviceIdList[], listing unique names of web cameras.
This property is useful, for example, if you want to store the last used web camera. Names in VideoDeviceList[] are not necessary unique, indexes of devices may be changed when the computer is rebooted, so a value from VideoDeviceIdList[] can be used.

Fixes
- H.264 stream was not played via HTTP.
- fix in the camera search
- very rare bug in media server
- very rare bug in closing UDP connection
