TVH recordings additions

[adamsutton]

Added support for recordings being retrieved via HTSP (requires v7 server) rather than HTTP. This overcomes some of the limitations of HTTP in relation to in-progress recordings etc...

Added support for recordings folders (requires HTSP v7 capable server).

HTSP v7 is still WIP, but if anything changes I'll update.

this broke seeking in recordings for me with tvheadend 3.2. didn't investigate

[adamsutton]

@opdenkamp HTSPv6 seeking is now fixed. Also directory listing was incorrect, also fixed.

30 second skip still doesn't work. it's also a lot slower than before this patch.

[adamsutton]

@opdenkamp hmm, ok, I'll have another look.

[adamsutton]

@opdenkamp I'm not seeing this, I am running a test server (built from release/3.2) and I have tested with pvr.hts before and after the change.

30s skip works fine in both cases and I don't see any difference in speed/performance.

I have double checked and the commit refs match those attached to the PR so I am not running the wrong version etc..

The only thing I'm seeing is performance for skipping via HTSP method (i.e. with new code) is not as good as I'd expect, I need to take a look at this.

[opdenkamp]

as discussed on irc, i won't merge this pr now because it doesn't fix or improve anything at the moment.

[adamsutton]

@opdenkamp agreed, I think I've got to the bottom of the HTSP file serving problems I just need to implement a solution.

However I cannot repeat your problems with the mods against HTSPv6 server (i.e. HTTP streaming) the performance for me is identical pre/post these mods.

[adamsutton]

@opdenkamp ok, that solves the skip performance problems. It does not however work (ff) with a couple of TVH recordings files I have, but as discussed on IRC I'm pretty sure this is a problem with the file and nothing to do with HTSP methods.

Using the same file via the old HTTP streaming OR direct file IO in XBMC does not work properly. (oh and VLC whines like made about it).

Using a decent file (i.e. a dvd->mkv/h264 rip) works just fine.

Can you take another look at the performance on your 3.2 TVH server as I cannot repeat what you mentioned, for me it works fine now.
