The file name "lc3.h" in the ETSI LC3plus package may conflict with the
actual LC3 codec, so try to find a file "lc3plus.h" instead. Also try
to find a pkg-config dependency for it first (in which case use lc3.h,
assuming it's in different directory). This can be fine tuned, if
something starts to package that library.
Use the new requested buffer field to only queue the amount of samples
required by the resampler for the current quantum. This avoid spikes
when the maxsize block of samples is processed.
Fixes#2353
LC3plus expands 509 bytes input -> 7680 bytes output, which is bigger
than current decode buffer.
Make the decode buffer bigger, and put it on heap, not stack.
Codecs may need to fragment a single encoder frame across multiple
packets that are sent consecutively.
Allow codec->encode() to set need_flush=NEED_FLUSH_FRAGMENT, so that
sink should immediately call start_encode + encode with NULL input data,
to produce the next packet.
Previously, other return values than need_flush=1 were unused, so no
need to bump codec ABI for this.
Add some more context to the match rules and return how many properties
changed. If something changed, send all the properties as updates
instead of just the original changed ones.
When some blocking method is performed on the process thread, like
jack_connect() mark the data thread as blocked while we wait for the
thread loop to process the result.
If we then try to do a blocking _invoke from the thread loop on the
data thread, make sure we don't wait for it to complete or else we
deadlock.
We need exactly 4 hex characters, everything else is refused. We
also copy those characters directly to the output string without
assuming any encoding.
See #2337
Codec switch flag should be cleared on device connection status change,
to deal with codec_switched() callback not being called if device is
suddenly disconnected.
When device is disconnected, running codec switches are not meaningful,
and should be stopped.
The codec switch callback may also trigger A2DP profile switch, which
may reconnect the device. Fix it so this does not happen.
See #2334
With this commit, something like
`pw-link -d my-device alsa_output.headset` can be used to destroy
all links from output ports of `my-device` to input ports of
`alsa_output.headset`.
