The unconfigurable resync period of 10 seconds was not frequent
enough to keep my own ALSA device in sync with the AirPlay stream.
Now the period is configurable. The default is still at 10
seconds, to prevent any change in behavior unless opted in by
the user.
Currently the adjustment causes a tiny "click" distortion in the
ALSA output, so it is better to make the check as infrequent as
possible, while still being frequent enough to stay in sync
over lengthy sessions of playback.
Added source_sample_rate, target_sample_rate to alsa_session.
This is a first step toward rendering ALSA at a different
sampling rate than the AirPlay stream, so that (a) we will
be able to dynamically adjust the ALSA sampling rate for an
improved sync algorithm, and (b) later, a more generalized
resampling algorithm can accommodate very different hardware
sampling rates like 22050 Hz or 48000 Hz.
Reworked alsa_session_free() so that it can be used to
tear down a partially initialized alsa_session if an
error occurs in the middle of alsa_session_make().
This simplifies the error handling logic in alsa_session_make().
This refactoring will be helpful later when resampling is added,
because more data structures will be dynamically allocated
during initialization.

Some clients aren't really capable of authenticating + some users probably
don't want to enter a password for the web interface. This option allows
clients on for instance the local network to connect without authentication.
For people who want to avoid the web login, or want to get around pairing
problems. This is also added because commit #e59a1a1 means that all
Remotes are now subject to auth, not just those with a user-agent name that
starts with "Remote".
This also introduces a new config option to define a default playlist
folder. The default playlist folder is used by forked-daapd if the
playlist is not a full virtual path (simpifies creation of playlists
with mpd clients).
Support a separate mixer_device configuration file option for
advanced ALSA configurations. Previously, ALSA local output
happened to work becasue "default" is valid as both a PCM and a
mixer. Now you can separately specify the device name for PCM
output and mixer operations.
In my setup, I am using the following setup:
card = "default:CARD=NVidia"
mixer = "Front"
mixer_device = "hw:CARD=NVidia"
Add a new general config setting allow_origin that is included as
Access-Control-Allow-Origin header in http responses. This allows to make http
request against forked-daapd from browsers with enabled CORS
(https://www.w3.org/TR/cors/) via JavaScript XMLHttpRequest.
Per default the setting is not defined and no Access-Control-Allow-Origin header
is included in the response.
stops (default is clearing the queue) and if true do not clear the
queue.
This option is necessary because some dacp clients rely on the queue
being empty if player is stopped. Retune for example does not always
show the queue contents if player state is stopped.
Also includes the skeleton for perhaps supporting video in the future. Adds more fine-grained
ffmpeg/libav compability checks. Dependency on libavresample/libswresample exchanged with
dependency on libavfilter, which seems more versatile.
introduces a dummy output for local audio
Changes configure.ac to control the with-alsa and with-oss4 separately.
This makes it possible to only use the dummy output and compile without
alse+oss4.
- introduced new section in config file for sqlite pragma settings,
added config for artwork cache
- added setting of pragma synchronous, cache size and journal mode to
daap cache
