Raspberry pi play shor movie's (.Net/Mono/DotNet)

[jgcramer]

Hello,

I have a Raspberry pi what i use to show information on a screen with different screens (jpegs) on it for eatch specific customer.

But now i wanne show short movie's on the Pi, when a specific customer is in front of the screen.

I use .Net to program with Mono on the Pi.

Now my question:
What is the best way to play the movie, also becasuse of the limits of the Pi.

dotnet, mono, .net

omxplayer file.h264

omxplayer file.h264

This application runs stable and fast on the pi with mono?

I have googled but diddent find some DotNet helping files.

This is a native Linux program which has to be spawned from
within Mono with something like exec() (PHP) or subprocess.call()
(Python). No idea how that is called in C#.

You can pass parameters to omxplayer, like coordinates X and Y, aswell as width (X2 = X1 + width) and height (Y2 = Y1 + height):

Code: Select all

Usage: omxplayer [OPTIONS] [FILE]
Options :
         -h / --help                    print this help
         -n / --aidx  index             audio stream index    : e.g. 1
         -o / --adev  device            audio out device      : e.g. hdmi/local

         -3 / --3d mode                 switch tv into 3d mode (e.g. SBS/TB)
         -y / --hdmiclocksync           adjust display refresh rate to match video (default)
         -z / --nohdmiclocksync         do not adjust display refresh rate to match video
         -t / --sid index               show subtitle with index
         -r / --refresh                 adjust framerate/resolution to video
         -g / --genlog                  generate log file
         -l / --pos n                   start position (in seconds)
              --boost-on-downmix        boost volume when downmixing
              --vol n                   Set initial volume in millibels (default 0)
              --subtitles path          external subtitles in UTF-8 srt format
              --font path               subtitle font
                                        (default: /usr/share/fonts/truetype/freefont/FreeSans.ttf)
              --font-size size          font size as thousandths of screen height
                                        (default: 55)
              --align left/center       subtitle alignment (default: left)
              --lines n                 number of lines to accommodate in the subtitle buffer
                                        (default: 3)
              --win "x1 y1 x2 y2"       Set position of video window
              --audio_fifo  n           Size of audio output fifo in seconds
              --video_fifo  n           Size of video output fifo in MB
              --audio_queue n           Size of audio input queue in MB
              --video_queue n           Size of video input queue in MB

For example upper half of full hd (1920x1080) screen:

Code: Select all

omxplayer --win "0 0 1920 540" myfile.mp4

Attention: omxplayer "overlays" your current application. If you create your user interface, be sure to not locate any interactive controls in the area you would like to have your video.

In c# mono it might be something like this:

Code: Select all

Process.Start(new ProcessStartInfo("/usr/bin/omxplayer", "--win \"0 0 1920 540\" myfile.mp4") { UseShellExecute = false });
