From the old bug db, #24:
Getting rid of the Ringbuffer way of timeshifting would be nice:
* Ringbuffer's slow for local access (ie, uses the network)
* Multiple semi-complicated codepaths to support the Ringbuffer and normal
file access.
* Unable to save an in-progress show from the timeshifting buffer.
The idea would be to:
* Just use normal files for timeshifting.
* Automatically change to a new physical file on channel change or program
change (from the guide data). Would also need to segment files every few
hours, in order to allow very long programs to be timeshifted and still
offer the ability to limit space used for timeshifting. Could just punt
on this and just require enough recording space, though.
Basically, the recorder would need to create a chain of files to play
back,
and share that with the frontend on a periodic basis (store in db, send a
message out to reload?). The recorder would have to be able to chunk
the files based on a GOP end, so playback could continue from the
beginning of an arbitrary file.
The player engine would need to be able to seamlessly change from
playing one file to the next.
I think the hardest part would be dealing with seeking over file
boundaries, but even that shouldn't be too bad.
