r_e_c_u_r

an open diy video sampler

r_e_c_u_r is an embedded python/openframeworks application on raspberry pi3 that uses input from the keypad to control video while displaying a simple text ui on a rpi lcd screen

in-depth video demo

features

• seamlessly loop video through rpi's HDMI or composite out
• intuitively browse video files from external and internal disk and map them into r_e_c_u_r
• load and trigger video samples from numbered slots in the sampler bank
• dynamically set and clear the start/end points of each sample as it plays
• control and sequence all inputs and more with midi-usb
• many sampler modes for varied playback including: repeat, one-shot, gated, random, fixed-length, random-start and more
• exhaustive and extendable settings menu to suit your use

extensions

as of V2.0 the r_e_c_u_r platform has been extended in a number of directions to complement live performance and _recur_ , the original video playing engine:

• _captur_ : input live video via CSI or USB , for live sampling and processing
• _conjur_ : glsl shader engine, map and trigger shader files and control parameters in real time; generate video or process and mix existing sources
• _detour_ : in-memory frame sampling (up to 500 frames), video scrubbing, playback speed and direction control, finger drumming
• toggling internal feedback + strobe effect

NOTE: most of the new V2.0 features are optimised for sd composite video output. Some of these extensions will work over HDMI but they are not fully supported - especially the live video input struggles

main objectives:

• Affordable : reducing the entry cost to performing with video
• Extendable : laying the foundations (of a user interface and code style) that can be easily iterated on by the community
• Simple : easy to operate (abstracted completely from ‘driving’ a raspi ) , easy to build (no technical computer install-y or circuit-y knowledge required to diy) , easy to develop (human readable code, inviting amateur/first time coders to contribute)

status

The nature of this project is to be open-ended and community driven. my r_e_c_u_r already solves the problems i initially built it for. what happens next depends on how it is used and received by you. if you like the idea please let me know / get involved !

contact, donation and thanks

you can find me (and others) at https://scanlines.xyz , an online diy av community space. theres a r_e_c_u_r channel in the chatroom: https://chat.scanlines.xyz/channel/r_e_c_u_r there is also a facebook user group : https://www.facebook.com/groups/114465402691215/

all feedback is appreciated. if you want to donate to this project you can do so with the above email via paypal : everything i receive will go into improving r_e_c_u_r. cheers to Leo Browning for the 3d modelling and vector art and to Ben Caldwell for heaps of help with the code!
