Fade in and out video and images fullscreen via OpenSound Control messages.

Precompiled for macOS and Raspberry Pi OS.

Written during my artist-in-residency at Anglia Ruskin University, Cambridge spring 2016.

Built with openFrameworks v0.11.2 under macOS (64bit 10.14.6) and under RPi OS (32-bit Buster). Should also work under Linux and Windows but you will need to compile it yourself using openFrameworks.

For older operating system, download builds from the releases page.

• Download and extract the zip archive from https://github.com/redFrik/yetanotheroscmovieplayer
• Double click yetanotheroscmovieplayer_osx.app

and a black window should fill the screen. Type 'i' to see the status and 'ESC' to exit.

Now copy your own images and/or movie files into the data directory and start sending OSC commands from Python, JavaScript, PureData, SuperCollider or whatever - see protocol and testcode below.

• Jumping backwards in time in a movie can be slow. Try encoding your video as PhotoJPEG or other similar non Motion JPEG format or use the HPV version.
• To enable loading media files from the data directory you probably need to un-quarantine the .app and remove translocation. You can do this either manually - by moving the application outside of the folder and back again - or with the following terminal command...

  xattr -cr yetanotheroscmovieplayer_osx.app
  xattr -cr yetanotheroscmovieplayer_hpv.app

There is also a version for the High Performance Video Eco-system. This one is optimised for scrubbing and playing back high resolution video.

A .hpv file can be created by first using ffmpeg to convert a video into a folder of png files, and then give that folder as input to HPVCreator. The first step, .mov to .png conversion, could look like...

ffmpeg -i input/yetanotherdemo.mov -vsync 0 dest/out%05d.png

First open a terminal window and type...

sudo raspi-config

Increase the RPi's GPU memory to >= 128 and select GL (Fake KMS) under Advanced Options / GL Driver.

Next install this software by typing...

git clone git://github.com/redFrik/yetanotheroscmovieplayer --depth 1

To start type...

cd yetanotheroscmovieplayer
./yetanotheroscmovieplayer_rpi

and a black window should fill the screen. Type 'i' to see the status and 'ctrl+c' to exit.

Now copy your own images and/or movie files into the data directory and start sending OSC commands from Python, JavaScript, PureData, SuperCollider or whatever - see protocol and testcode below.

On Raspberry Pi type crontab -e and add the following line to the end...

@reboot /home/pi/yetanotheroscmovieplayer/yetanotheroscmovieplayer_rpi

• Jumping backwards in time in a movie can be slow. Try encoding your video as PhotoJPEG or other similar non Motion JPEG format.
• Because the files are loaded from disk (SD card) when started there might be a small delay. A preload command that enables fast triggering is on my TODO.
• There is also a special RPi build for Adafruit's PiTFT display. Start it with ./yetanotheroscmovieplayer_rpitft.
• Palindrome looping does not yet work in the Raspberry Pi version.
• Negative speed (backwards) does not yet work in the Raspberry Pi version.
• Also, for the rpitft version to avoid flicker you will want to log out and exit the desktop before starting this app (via SSH or startup script).
• To hide the blinking login cursor when automatically string type sudo nano /boot/cmdline.txt and add vt.global_cursor_default=0 to the line.
• If playing video files fail on RPi make sure you have memory split in raspi-config set to something => 128.
• The error [ error ] ofAppGLFWWindow: 65544: X11: The DISPLAY environment variable is missing might appear if running via SSH. The command export DISPLAY=:0.0 should make the error go away. Or log in via VNC and try.
• This is not working under Raspberry Pi OS Lite at the moment (tried with sudo apt-get install xorg libgstreamer-plugins-base1.0-0 libglfw3 libfreeimage3 libboost-filesystem1.67.0 liburiparser1).

This simple application was built using openFrameworks and you can easily modify it and/or build it for other operating systems that oF supports.

• Download and install openFrameworks for your platform.
• Follow the oF setup guide and make sure you can compile example projects.
• On macOS:
  • Copy the folder sourcecode/yetanotheroscmovieplayer_osx into of_v0.11.2_osx_release/apps/myApps/
  • Open the file yetanotheroscmovieplayer_osx.xcodeproj in Xcode or yetanotheroscmovieplayer_osx.code-workspace in VSCodium or VSCode.
  • Make sure the target is yetanotheroscmovieplayer_osx Release
  • Build (Cmd+b in Xcode, Cmd+Shift+P - run build task in VSC)
  • The resulting application will be in the bin folder.
  • Use yetanotheroscmovieplayer_hpv to build for HPV support. Also install the ofxHPVPlayer addon.
• On RPi:
  • Copy the folder sourcecode/yetanotheroscmovieplayer_rpi into openFrameworks/apps/myApps/
  • Change directory to that folder with cd and type make -j 3
  • The resulting application will be in the bin folder.
  • Use yetanotheroscmovieplayer_rpitft to build for TFT screens. Also install the ofxPiTFT addon.

• Preload command
