respectively, during replay (reported by Thomas Maass).
|
||||
- The Yellow button in the main menu no longer acts as "Pause" if "Pause key handling"
|
||||
is set to "do not pause live video" (suggested by Ulf Kiener).
|
||||
- The code for distributing recordings over several video directories has been
|
||||
removed. VDR now by default assumes that the video directory is one big disk.
|
||||
If you absolutely need to use several separate disks to store recordings, you can
|
||||
write a plugin that uses the new cVideoDirectory API to implement the necessary
|
||||
functionality (see PLUGINS.html, section "The video directory"). You can copy the
|
||||
respective code from previous versions of videodir.c.
|
||||
IMPORTANT NOTE: If you write a plugin that implements a distributed video directory,
|
||||
=============== be sure to make cVideoDirectory::Rename() follow symbolic links!
|
||||
This functionality was never implemented in VDR and it therefore
|
||||
used a workaround in cutter.c. See the section marked with
|
||||
// XXX this can be removed once RenameVideoFile() follows symlinks
|
||||
in previous versions of cutter.c.
|
||||
+ CloseVideoFile() is obsolete and has been removed.
|
||||
+ The functions OpenVideoFile(), RenameVideoFile(), RemoveVideoFile(), VideoFileSpaceAvailable(),
|
||||
VideoDiskSpace(), RemoveEmptyVideoDirectories(), IsOnVideoDirectoryFileSystem() and
|
||||
PrefixVideoFileName() are now static members of cVideoDirectory and need to be called
|
||||
with the proper prefix.
|
||||
+ The name of the video directory is now available through cVideoDirectory::Name().
|
||||
The former global variable VideoDirectory is still there for backwards compatibility,
|
||||
but will be removed in a future version. Comment out the line
|
||||
#define DEPRECATED_VIDEODIR
|
||||
in videodir.h and recompile your plugins to see whether your code will work without
|
||||
this variable. If you get a compile error, replace it with cVideoDirectory::Name().

By default VDR assumes that the video directory consists of one large

volume, on which it can store its recordings. If you want to distribute your
|

recordings over several physical drives, you can derive from <tt>cVideoDirectory</tt>,

||||
|
||||
<p><table><tr><td class="code"><pre>

See the description in <tt>videodir.h</tt> for details.

<p>
|

You should create your derived video directory object in the
|
||||
<a href="#Getting started"><tt>Start()</tt></a> function of your plugin.
|
||||
Note that the object has to be created on the heap (using <tt>new</tt>),

and you shall not delete it at any point (it will be deleted automatically

when the program ends).
