Comment:
(In [12618]) Fixes #1648. Fixes #2209. Fixes #2722. Fixes various Firewire
problems.
This is a sync from the mythtv-firewire branch, see it for detailed
descriptions.
This removes any existing Firewire cards, these must be recreated with
GUID. The Linux firewire recorder used the port and node on the bus the
STB was on to identify a recorder, this is not unique across bus resets
and is not unique in the presence of firewire hubs. The Mac firewire
recorder just randomly selected STB's for the recorders. This changes the
code to use the GUID, which is unique to each firewire device, to identify
which one to use for each recorder.
We required the user to select the STB model, even when we knew this from
the vendor and model ID. This automatically selects the proper STB model
if we know it, otherwise we default to a channel changer that will work
with any AV/C compliant recorder (though it may be slower).
IEEE-1394 Bus resets were not handled properly, particularly in the Linux
firewire recorder. This adds a reset handler which will find the recorder
if it is still on the bus and resume recording.
We always leaked memory when using libavc later than 5.3, configure will
now detect the version and if MythTV is compiled with 5.3 present it will
require it and will not leak memory. MythTV will still compile with older
versions, but we will still leak memory if the user later upgrades to 5.3
without updating MythTV.
This also merges the IPTV & Firewire TS packet listener classes to a
single class in mpeg/streamlisteners.h and merges some Mac & Linux
Firewire classes to avoid code duplication.
There is still no channel scanner for firewire and the automatic bus reset
code (to deal with 5C channels) has been disabled in the merge due to
remaining problems, use the mythtv-firewire branch if you want the latest
and greatest.
