* This is done by watching to registrar notifications
and providing a minimal service to contact the
media roster in private API. The roster use this
service to automatically reconnect to the media_server.
* Improve consistency by adding a BMediaRosterEx destructor
and using it for the specular functionality of ctor instead
to use the father's class destructor.
* Avoid double initialization of MediaInitializer that
becomes MediaRosterUndertaker.
* Remove superfluos call to BMediaRoster::Quit()
in media_addon_server.
The media_server is now able to remember the timesource associated to
a certain registered_node and always remove it when the owner
application crash, Fixes Ticket #11852
The AddOnManager was in the global namespace, clashing with application
classes with the same name.
The input_server has an AddOnManager of its own. When the
shortcut_catcher filter was loaded by said AddOnManager, it in turn
loaded libgame.so, which in turn loaded libmedia.so, where an
AddOnManager was created for the global AddOnManager instance in
libmedia.so. Unfortunately the wrong AddOnManager, the one from the
input_server, was created. This lead to two AddOnManagers being active
in the input_server which very well could be responsible for #11049
and #11280.
This was a regression since the move of the AddOnManager from the
media_server to libmedia.so in hrev47086. This also fits with the two
tickets.
I actually noticed the problem when debugging the shutdown process of
the input_server, where the destruction of the wrong AddOnManager
caused a deadlock with itself.
* Use the preferred time source (GetTimeSource) for the node
* Fix node releasing when creating the connection fails
* Add virtual slots and padding
* Refactor _Connect method
The media server tried to use node monitoring to dynamically add and
remove plug-ins, but it isn't that useful:
* When a plug-in is added, applications would have to query the media
server to get an up to date list of available formats. For example
MediaConvert populates its format menus on startup.
* When removing a plugin, if an app already had it loaded, there is not
much that can be done to keep it working.
* The list of plugins was not sorted by directories (user vs system
add-ons), so the directories were re-scanned to make sure user add-ons
were returned first, rendering the node monitoring less interesting.
Now, the format handling is done by each application. The node
monitoring is removed, instead the apps will scan the plugin directory
when first using the media kit classes. Restarting the application is
needed to update the media formats list.
that they can modify the media_format passed in. For example they
can store information in the user_data section. I don't actually
use this anymore, but it may come in handy again.
AVFormatWriter:
* Adjust the AVCodecContext flags not only for video, but also
for audio streams (as the API example does). This mechanism
may not yet work, since the AVCodecEncoder actually uses a
different AVCodecContext instance.
* Use the encodeInfo->flags and specify the key frame flag
for the AVPacket. This finally makes videos encoded on Haiku
seekable.

SeekedTo(), since it's only informative to decoders. They
can't modify the seeked frame/time. This also mirrors what
all existing decoders were doing in Seek(). BMediaTrack
is simplified accordingly (resolved two TODOs).

BMediaFiles and about BMediaTracks in BMessages. As an
example, one can get chapter meta-data or the language
name of an audio-track.

* The media_addon_server before unloading addons need to be sure the nodes are deleted.
For instance, applications could keep references on global nodes, thus preventing deletion.
To release all references, the media_addon server uses a new method BMediaRosterEx::ReleaseNodeAll().
* Quit the MediaRoster looper when quitting media_addon server before unloading addons.

Changed strings to sentence case in various places. This is the
case-misc.diff part of ticket #5169.

* Added myself to copyrights, since I added some stuff to MediaExtractor.

the internal dependencies into account. This should fix bugs #5166, #5120,
and #5150.
* Also, the time source object manager, as well as the dormant node manager
are now recreated on media roster restart (when the media server is
restarted).

accessible from the outside.
* Instead, request_data now retrieves/releases a reply port on its own.
* There were some more places that still used write_port()/read_port() instead
of QueryServer().

usual structures.
* Also, they now use the QueryServer()/SendToServer() functions instead of
duplicating them.

* Fixed at least two reference counting problems, but nodes from killed teams
still remain alive (will look into this at a later point).
* GetLiveNodes() is now using transfer_area() as well.
* Made all sizes in the SendTo*() and Query*() functions size_t.
* Replaced reinterpret_casts with static_casts when casting void pointers.
* Ordered the request/reply structures by target.
* Tried to consolidate the use of add_on vs. addon.
* More cleanup.

look into this now.
* Renamed the MMediaFilesManager to MediaFilesManager.
* Got rid of its Map usage, we're using std::map now instead.
* The media_server is using an unsafe method to transfer areas from the server
to the client. I've changed this for the BMediaFiles API to use Haiku's new
transfer_area() function. However, this seems to cause the above mentioned
problems.
* Improved naming and data exchange structures used for the BMediaFiles API.
* Fixed BMediaFiles leaking its lists.
* Cleanup.
git-svn-id: file:///srv/svn/repos/haiku/haiku/trunk@34554 a95241bf-73f2-0310-859d-f6bbb57e9c96
* Renamed global variable _DormantNodeManager to gDormantNodeManager.

each buffer, and once for each buffer group.
* Also, SharedBufferList::Get() now gets the area to clone from itself, if
necessary, the caller no longer has to provide it.

into smaller parts:
media_addon_server:
* Removed (broken) use of (broken and inefficient) home-brewn Map, and List
classes. This also fixes a crash on shutdown when used with the malloc_debug
implementation. It's using stl::vector, and stl::map now instead.
_shared_buffer_list:
* Renamed _shared_buffer_list to SharedBufferList, and put it into the BPrivate
namespace. Also, made a class out of it.
* Separated shared buffer list creation from cloning.
* Enlarged maximum number of buffers to something that is not that evil, but
actually uses the space it has (ie. is a useful multiple of
shared_buffer_info that fills a multiple of B_PAGE_SIZE as much as possible).
* No longer drops into the debugger if the
* The list that is currently used is very inefficient for the features it
provides though (no change there).
_buffer_id_cache:
* Renamed to BufferCache, and put it into the private namespace
* It now deletes its buffers on deletion; since the BBufferConsumer will be
gone, too, at this point, there is little chance that there are still buffers
in use.
* Also, it's now using std::map instead of the (see above) Map class.
BBuffer:
* Got rid of the fBufferID member.
Misc.:
* Got rid of the global "team" variable; the media kit is now using the
private app kit's current_team() now.
* Added a lot of missing error checks (mostly memory allocations).
* Renamed fields like "flavorid" to flavor_id, renamed "dfi_*" fields to
something more detailed.
* Moved ServerInterface.h from src/servers/media/ to headers/private/media.
* Notifications.h was not self contained.
* Added missing licenses.
* Lots of cleanups, and coding style fixes.
What this doesn't fix:
* Bug #4954 which started all this (this comes next, though)
* Deinitialization is broken, as the PortPool is uninitialized too early, and
still used afterwards.
* The strange add-on monitoring code in the media_addon_server
git-svn-id: file:///srv/svn/repos/haiku/haiku/trunk@34500 a95241bf-73f2-0310-859d-f6bbb57e9c96
regards to locking and seeking.
* Furthermore, we now not only cache 4 chunks, but chunk up to a certain
memory size (MediaExtractor uses 1 MB for now).
* Since I still have occasional hickups, it looks like this wasn't the main
cause for our audio problems. Still, this will reduce drive access
considerably during play.

server with GCC4 in a GCC2 system (and vice versa). See #4920 which this
patch closes, too.
git-svn-id: file:///srv/svn/repos/haiku/haiku/trunk@33997 a95241bf-73f2-0310-859d-f6bbb57e9c96
* Fleshed out the Encoder API to support parameter setters/getters and returning
a BView for configuration. (Not yet sure if this is a good idea.)
BMediaTrack:
* Implemented all but one of the unimplemented methods in BMediaTrack. It should
be working as far as that class is concerned, unless I missed some of the
vision. ReplaceFrames() remains a stub, added a comment on why it probably
stays that way.
* Release the Encoder reference in the destructor.
FFmpeg plugin:
* Refactoring to delay opening the AVCodec until encoding the first chunk,
so that we can still adjust parameters.
* Support adjusting parameters via [Set|Get]EncodeParameters(). Currently,
only quality is supported, added TODOs about supporting the bit_rate setup
versus the automatically calculated bit_rate.
* Extended EncoderDescription by a bit_rate scale. The Encoder calculates the
raw bitrate needed by the current media format, and then divides that
number by the specific codec's bit_rate_scale, while taking into account the
desired quality. This seems to work very well already (tested with MPEG4),
although a lot more parameters could be specified for libavcodec, depending
on the desired quality.
* Enabled the ogg muxer in libavformat, although it is currently still disabled
in MuxerTable.cpp, because it rejects unknown codecs. Added TODO to this
effect.
