Sound
Previously, TRVMicrophone used the system default audio input device (usually, it is a microphone). In the new version, you can choose the device using the properties: AudioInputDeviceIndex, AudioInputDeviceCount, AudioInputDeviceList.
New events are added (TRVCamSender.OnEncodeAudio and TRVCamReceiver.OnDecodeAudio). You can use them is you want to encode and decode audio data manually.
Local web cameras
RVMedia can decode different formats of video from local web cameras (YV12, YUYV, YUY2, YVYU, UYVY, NV12, etc.) itself. Previously, it relied on a converter that converts these formats to RGB (it may be installed or not).
In addition to choosing from a list of video modes supported by a web camera, the new version of RVMedia provides a simplified way to choose video resolution, by assigning to TRVCamera.VideoResolution property.
Motion detection
RVMedia included a motion detection mechanism, but it was hidden.
It is used internally in TRVCamSender to send only changed fragments of video frames.
In this version, we published this mechanism as TRVMotionDetector class, you can use it in your applications.
FFmpeg
In this year, FFmpeg 3.0 was released. In this release, its API was changed, this version of FFmpeg could not be used in RVMedia 4.0.
This release supports FFmpeg 3, as well as 2 and 1.
Also, correction for using FFmpeg in 64-bit projects were made.
IP cameras
In this release, we added support for newer (H.264) Foscam cameras, including configuration and movement control. Older versions of Foscam cameras are supported as well.
Note: H.264 support in IP cameras requires FFmpeg
Media server
In this version, we added support for named and password-protected groups on the media server (TRVMediaServer component).
Groups may be used to implement chat rooms.
To-do: this version does not support group deletion, it will be implemented in future.
Delphi and C++Builder support
This update supports Delphi and C++Builder 10.1 Berlin.
A help file is integrated in RAD Studio XE8, 10 Seattle, 10.1 Berlin (F1-help and menu "Help | Third-Party Help")
In this update, we changed a structure of packages.
Previously, we used the following scheme:
- for C++Builder, a single package, for example RVMediaCB10.cbproj
- for Delphi, two independent packages: 32-bit designtime package (e.g. RVMediaD10.dproj) and independent 64-bit runtime package (e.g. RVMediaD10_64.dproj).
In the new version, we separated packages on runtime and designtime:
- for C++Builder, runtime 32-bit package (e.g. RVMediaCB10.cbproj) and dependent designtime package (e.g. RVMediaCB10_Dsgn.cbproj)
- for Delphi, runtime 32&64-bit package (e.g. RVMediaD10.cbproj) and dependent designtime package (e.g. RVMediaD10_Dsgn.dproj)
Because of this change, we highly recommend to uninstall the previous version before installing a new one (otherwise, unused *_64 packages will remain in the system)
