Hi list, A few weeks ago, when we visited Sourcefabric in Berlin, I started working on a small example for Martin Konečný of Airtime. The task was to have an HTTP input with the ability to change the URL, transitions between different relayed HTTP streams, and transitions between HTTP and "normal" streams.
To do this I had to introduce a new feature (the "source_url" metadata added to HTTP streams) and fix a bug (remaining time estimation broken in cross and smart_cross). If you want to try my stuff, you need to update to the latest git code. The solution is a fairly complex script, attached to this mail for lack of a better medium. The script defines three functions that may be independently useful: * one for creating an HTTP input with a more convenient command for changing a URL and restarting (currently requires active wait); * one for applying transitions between different relayed HTTP streams (different URL) using cross (currently the transition only fades, but it's easy to change); * finally, an advanced trick to smoothly fade in and out an HTTP stream on top of a normal stream, which involves triggering a switch in advance, but avoiding to trigger it for short disconnections of the HTTP input. The script includes a test setup that you should be able to adapt quickly. It uses a vumeter coupled with an audio output for a better control of what's happening. For now, these functions are not intended for beginners. Before asking questions on how to use or tweak them, please make sure to read the script and understand its structure at a high-level -- in particular, I've included comments on what can be tweaked and what should be handled with care. Have fun, -- David PS: For the record, we also investigated a more advanced solution involving source.dynamic(). For this task, it's not an interesting approach as it is only more complex and (currently) unstable, but it lead to interesting optimizations that I still haven't finalized. ------------------------------------------------------------------------------ Don't let slow site performance ruin your business.
