OPUS Projektor Manual
Object Reference
(especially a page on a 16:10 display). Use this property to position the video image either
centered or in one of the corners. If the video is displayed in a frame, keep the frame size in a
4:3 format to avoid blank spaces.
Note that H264 video always fills the complete object. If the stream is in a 16:9 format, give
the frame the same format to avoid distortions.
Scaling Factor
This property currently has no effect. Analog video will always be scaled so that the whole
image is shown in a 4:3 format. H264 video will always be scaled to fill the whole object
(adjust object size to stream format, to avoid distortions).
To further customize the look of the video image, the camera variables can be used. Note
that these only have an effect on the analog camera inputs.
The properties above are all applied as soon as the application switches to the page that
contains the video frame. Other settings that were made with the camera variables are
overwritten.
Please note that the size and position variables shall not be set to higher values than the
according device resolution, e.g. for a device with resolution 800 x 480, the x position and the
width should not be set to a higher value than 800, and y position and height should not be set
to a higher value than 480.
Ethernet camera requirements and limitations
General:
·
The properties of the camera itself like resolution, IP, etc. can currently not be changed by
the device. A tool to change camera settings via ISO 17215 is available in the program.
See here .
·
Rotation is supported.
·
The higher the resolution and/or bandwith of the camera is, the worse the performance on
the screen will be. A rough recommendation is to keep it under 15 Mbit/s.
·
It is possible to show the stream together with analog video on the same page. It is however
recommended to do this only on devices that have multi-core CPU. On single core CPUs
the performance might drop a lot.
·
Only one stream can be shown per page.
·
Ethernet needs to be activated on the device for the stream to be shown, see
@Ethernet0_applynstart and @Ethernet0_UpAtStart
·
@VideoStatus needs to be set to 1
H.264 via UDP/RTP / MJPEG via UDP/RTP:
·
H.264 / MJPEG video streams over Ethernet are only supported on devices with i.MX6
CPU.
·
The camera needs to use the RTP protocol via UDP/RTP to deliver the stream.
·
The camera can either send the stream directly to the IP address of the device or via UDP
broadcasts.
·
The UDP Port that the camera uses needs to be set in the "UDP Port" property of the frame
or page that shall show the stream.
H.264 via RTSP:
