Gstreamer 1.0 Custom Python Element

The goal of the project, is to write a Python program, built on gstreamer, which will stream video to an RTMP endpoint, recover from network failures, and re-deliver an video buffered during the network downtime. You will be part of a programming team, but will be fully responsible for this deliverable, and will be expected to provide informed advice on correct design decisions based on gstreamers capabilities and best practices. The project will be delivered in milestones, and time required must be estimated before each milestone begins. Scope of each milestone will depend on the results of that prior. Technical details: - Raspberry Pi B+ - Raspbian Jessie - Python 2.7 - Gstreamer 1.0 Note: A pre-built Raspbian image will be supplied. You must have your own Raspberry Pi hardware. Milestone 1: Write a small Python Gstreamer element (named "retry"), and supporting Python script 1. has one sink pin, and one source pin 2. buffers are simply routed from sink to source 3. downstream errors are captured, and element enters 'offline' mode - upstream is tricked into continuing to send buffers, so the pipeline keeps playing 4. while in 'error' mode, downstream is repeatedly 'reconfigured' to force re-attempt of network connection 5. when downstream finally succeeds, element returns to 'online' mode Pipeline will look something like: "videotestsource ! omxh264enc ! flvmux ! retry ! rtmpsink"
