Move the source offs, stride, data and size calculations out of the
destination loop. We only need to clamp the size to copy to the maxsize
of the destination buffer.
parse_sdp_a_rtpmap used c += strlen(c) + 1 to skip past the MIME type to the
rate/channels part, but if the a=rtpmap: line had no / separator, strcspn
returned the full string length and the +1 advanced past the null terminator.
Fix this by checking if / was actually found, returning -EINVAL if not.
JACK2 only sends -1 as the frames, meaning we should take the value from
the negotiated period as the frames to process.
We however send the actual number of frames and use the sync value to
decide how many frames to process. We need to be careful because a value
of 0 will cause a division by 0 so treat <= 0 frames the negotiated period
size as well.
Check that the params don't include more than MAX_CHANNELS of audio or
else we overflow the position array.
Adapt to the compiled value of SPA_AUDIO_MAX_CHANNELS but allow at least
128 channels.
It's a terrible idea, doesn't work so well (locks up the data-loop when
read is blocked) and a security mightmare. If you really need to pipe
samples through some program, do that somewhere else, like from the
command line with pw-cat and pw-record.
Normally, when loading a plugin feature, often a library.name property
is given as well. If the feature to load is not explicitly listed in
context.spa-libs, the library.name is used a fallback library.
Add an option to ignore this library.name and only use the
context.spa-libs entries. This makes it possible to only load explicitly
listed features in the config file and makes it possible to lock down
what plugins can be loaded.
Set the option to true by default for now, which keeps the existing
behaviour of using the fallback library. Add some more entries to the
context.spa-libs in case the option is switched off to make things
work.
Set the option to false for the minimal.conf.
Add a special 'blocked' spa-libs value that returns EPERM when trying to
load the factory.
Only allow loading the LADSPA filter.graph nodes for the LADSPA sink and
source. The most problematic part is the pipe filter, that allows it to
spawn arbirary programs as part of the filter.graph.
You can add a filter-graph to any stream with stream_props.
Use spa_steal_ptr to transfer props ownership when we can.
This fixes a problem in the upload stream where the props would be freed
twice when buffer allocation failed, once with properties_free and
then with stream_free.
If the SAP packet contains the MIME type string but no SDP payload after it,
sdp would point past the null-terminated buffer. Check that we are
still inside the packet before parsing the SDP.
