* Moved data locking in the internal buffer class, includes handling
of backend writes.
* Takes advantage of inheritance for getting the size. The choice is
made depending on the flags. This allow the implementer to easily
return a custom size by reimplementing GetSize. At the same time
a plain BAdapterIO can still have it's total size set, but the behavior
will change depending it's mutable or not.
* Some decisions are now made by considering everything in absolute
values.
* Other minor fixes.
* This is by default provided using a relative buffer. When the
client request a seek over the range we currently have, we will
ask the backend with a SeekRequested. When the backend operation
ended successfully, the client is required to call SeekCompleted
before to return. This will cause the offset to change and the
buffer is cleaned as result. Next data received will be considered
to be at a position equal to the offset plus the relative position.
* This class is provided as a safe multithreaded communication channel
between a BMediaIO-like interface and a Read/Write backend.
* Includes internal buffering and can be used to provide multithreaded
edit of the data.
* Current limitations include missing BOutputAdapter and
correct timeout handling.
* Future plans provide a BRemoteAdapterIO that using ports
and areas allow to easily send big data between processes.
* When the user isn't requesting a custom notification, it will
be a BMediaRoster job to do it.
* Reintroduce BMediaRoster::SyncToServices, this time based on local
message passing rather than a global semaphore.
* SyncToServices is used in launch_media_server to make the process
more launch_daemon safe and faster in the average case.
* It was an error to add notifications in the media_server.
* Fixes#12717.
* Remove SyncToServices, I will probably readd it in future
but this time using a local synchronization service more than
relying on the media_server to release the semaphore.
* Due to some discussions today in mailing list I decided
to step back and retry the initial way to notify media rosters
about media services status. It is woking by using two different
notifications for reconnecting to the media_server and notifying
the local subscribers.
* This speed up the media services restart.
* Sorry for the noise and very thanks for reviewing my code to
everyone.
* The global synchro semaphore is provided with the purpose of
being used to avoid threads lock up when the media_server is in
an undefined state. There's still room for improvements.
* BMediaRoster::SyncToServices lock up on a semaphore until
the multi_audio correctly connected to the mixer.
* There's no need to force the streamer plugin to use a
BMediaIO. This class is supplied to accomodate more smart uses,
but in certain cases it makes just things more complex. If a
plugin doesn't need to have an internal caching method, then it
will be simpler to implement a block-consuming BDataIO and let
the internal BMediaIOWrapper to deal with caching.
* Since the BMediaRecorder have an it's own estabilished policy
relating releasing the producer node we will not interfere with
it except when we are controlled from Cortex.
* This required to review various parts of the code, and
isn't probably still perfect. The main problem was an attributes
hell where redondance created a lot of problems, all this data
is now controlled mostly by the node.
* Header indentation changes needed too.
* People interested, please review!
* This is based on the patch from Fredrik Moden which was based on
the Oleg Krysenkov one.
* The original patch has been reworked by myself.
* Adapted the code to work with the new PluginManager API which
differently than before doesn't need to contact the media_server.
* BMediaRoster is now capable to know which nodes are
instantiated in this team. This is also a first step to make
them survive after media_server crashes.
* A control at BMediaRoster::Quit can notify if all nodes
were correctly released. Ideally at this point the local nodes
list should be empty.
* Add -fgnu89-inline flag for libroot/posix/glibc
* Change __GNUC__ == 4 to __GNUC__ >= 4

Fixes#11990, most of the changes had already been done.
* This has been necessary due to the undefined call order of
of static objects. Fixes#12315.
* The bug has been caused by the linker which free unused resources,
making the BMediaRoster to run in a zombie state. In this state
anything such as a message could make the looper to crash.
* The class is reintroduced with some differences though, we are
going to protect it from another thread calling Roster() while the
BMediaRoster is quitting and implement BMediaRosterEx::Quit.
* Unregister registrar notifications before we quit our thread. Avoid
to uninitialize anything from QuitRequested as it may cause problems.
* 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).

example, one can get chapter meta-data or the language

* 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.

the internal dependencies into account. This should fix bugs #5166, #5120,
and #5150.

are now recreated on media roster restart (when the media server is
restarted).

* 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().

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

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.
git-svn-id: file:///srv/svn/repos/haiku/haiku/trunk@32124 a95241bf-73f2-0310-859d-f6bbb57e9c96
info is not part of the media_format otherwise.
* Finished enough in the AVFormatWriter and AVCodecEncoder that we can now
actually create AVIs and MPGs and encode MPEG1, MPEG2 and MPEG4 video.
But no audio as of yet. Also, there is no bit-rate/quality setup, so it seems
libavformat is using the least possible bit-rate/quality.
* Enable some more muxers and encoders in the FFmpeg libs.
* Uses pixel format conversion from libswsscale, need to read the documentation
again, but I think it makes the plugin GPL.
* Fixed includes in libswscale/swscale.h, this is now an unmodified FFmpeg 0.5
header again (AFAICT).
git-svn-id: file:///srv/svn/repos/haiku/haiku/trunk@32043 a95241bf-73f2-0310-859d-f6bbb57e9c96
media_file_format as input, so that the Writer knows what kind of file is
needed.
* Also, since information about the stream format is going to be needed at the
Writer level as well, the AllocateCookie() method gets the stream
media_format.
* Fleshed out some aspects of AVFormatWriter, many TODOs are left.
git-svn-id: file:///srv/svn/repos/haiku/haiku/trunk@32025 a95241bf-73f2-0310-859d-f6bbb57e9c96
* Improved Encoder API towards what we need for the get_next_encoder() variants
and the BMediaTrack API.
* Implemented the rest of MediaWriter. Still undecided what to make of
AddTrackInfo(). BMediaEncoder has that as well, which hints that this is
something the Encoder needs to support. But it could also be that this is
only possible to support in Writer.
* Wired a lot of previously unimplemented methods in BMediaFile and BMediaTrack
needed for write support. If I have not overlooked anything, only the
parameter stuff is still unimplemented now.
This is all untested, since the FFMpeg Encoder and Writer are still only stubs.
git-svn-id: file:///srv/svn/repos/haiku/haiku/trunk@32013 a95241bf-73f2-0310-859d-f6bbb57e9c96
The AddOnManager in the media_server registers one encoder entry per
successful EncoderPlugin::RegisterNextEncoder(). This gives us a first idea
what media_format_family and input/output media_type is supported. The
mechanism may have to be extended, or the Encoder needs an API to specialize
a format further. In that case, the get_next_encoder() version that takes
optional _acceptedInput/OutputFormat needs to instantiate the plugin and
needs to ask the Encoder. But AFAIK, no app uses it like that anyway.

in PluginManager is reenabled. We use the media_codec_info.id to reference
a specific plugin, while the sub_id will be used to reference individual
Encoders that the plugin supports. No idea if that's how it was intented, but
some comments hint in this direction. I failed to mention this before, but
comments are of course very welcome on any of these commits, as always.

needed. I've added MediaPlugin* fields to Reader and Decoder plugin classes
which are set when the PluginManager hands out new instances. This way the
manager knows what plugin created the Decoder or Reader instance in the
Destroy*() methods and can decrease the reference count accordingly. Also added
some FBC stuffing to Decoder and Reader. All media plugins need to be recompiled,
in case anyone has some outside the Haiku tree.

as on Dano - since the functionality is already there, those two functions
aren't really needed, though, so we could remove them again.
* Cleaned up DataExchange.h, and added basic reply/request structs for anything
that needs an area.
* BControllable now uses a helper class ReceiveTransfer to deal with requests
with areas.
* Major style cleanup of MediaRoster.cpp, though one could still bury some
hours there...
