[Spice-devel] [PATCH v7 02/12] sound: Convert SndChannelClient to GObject

Mon Dec 5 12:07:29 UTC 2016
This patch is quite huge but have some benefits:
- reduce dependency (DummyChannel* and some RedChannelClient internals);
- reuse RedChannelClient instead of reading from the RedsStream
directly.
You can see that SndChannelClient has much less field
as the code to read/write from/to client is reused from
RedChannelClient instead of creating a fake RedChannelClient
just to make the system happy.
One of the different between the old sound code and all other
RedChannelClient objects was that the sound channel don't use
a queue while RedChannelClient use RedPipeItem object. This was
the main reason why RedChannelClient was not used. To implement
the old behaviour a "persistent_pipe_item" is used. This RedPipeItem
will be queued to RedChannelClient (only one!) so signal code we
have data to send. The {playback,record}_channel_send_item will
then send the messages to the client using RedChannelClient functions.
For this reason snd_reset_send_data is replaced by a call to
red_channel_client_init_send_data and snd_begin_send_message is
replaced by red_channel_client_begin_send_message.
