We should report roc sink and roc sink input latency to PulseAudio so it could be taken into account when PulseAudio calculates the overall latency.

PulseAudio can automatically adjust sink latency. When this happens, the size of the buffer requested from sink inputs is changed as well.

We should handle these updates:

• If the buffer size is larger than our target latency, we should increase our target latency, or the playback will break otherwise.

• If the buffer size is smaller than our target latency and the network latency is small too, we can decrease our target latency.

We should add support for changing target latency dynamically. There are two sources of the target latency updates: we can measure network latency during RTCP and we can get sink latency updates from PulseAudio. Then we should use the maximum latency of these two.

In this issue, we should do the following:

• add support for changing target latency at runtime
• handle PulseAudio latency updates (we likely should implement update_sink_requested_latency callback)

Implement pulseaudio module, providing source and sink that use roc as network transport.

Most likely, this module should be implemented on top of public API (#12) in a separate repo.

We need two features:

• receiver should put pulseaudio sink input to idle mode when there are no clients
• pulseaudio sink should put sender to idle mode when pulseaudio suspends sink

See also #20.

When sending from pulse audio (Ubuntu 20 LTS Desktop) with resampling in PA Daemon config to 48000hz 2channel f16, setting is not honored or configurable for the PA module and it will not connect to Raspberry Pi ALSA session.

With 44100hz there is an inability for the resampler to keep up even on LOW with the Pi 4:

We need a way to configure the following parameters:

• FEC scheme
• FEC block size
• packet length
• network encoding, rate, and channel set

We need to add corresponding module parameters or probably add some more high-level parameters and deduce configuration from them.

If we enable any clang/gcc sanitizer in SCons (e.g. --sanitizers=all), PulseAudio modules fail to load with an undefined symbol error:

E: [pulseaudio] ltdl-bind-now.c: Failed to open module /usr/lib64/pulse-12.2/modules/module-roc-sink.so: /usr/lib64/libroc.so: undefined symbol: __ubsan_vptr_type_cache
E: [pulseaudio] module.c: Failed to open module "module-roc-sink".

It seems this happens because they are not linked with -lusan and -lasan, despite that we're using clang++ with -fsanitize option as a linker.

Linking with these two libraries manually is likely not a good idea since there may be multiple versions of them on the system and their location is disto-dependent.

Ideally clang++ should add them automatically, but for some reason it doesn't do it.

Currently, we unconditionally set 44100, which may cause unnecessary resampling. It would be better to use the sink's rate instead.

I'd like to use roc on windows but there is not tutorial for building for windows.

Any chance?

We should add more receiver and sender parameters to PulseAudio modules, e.g. target latency and no playback timeout. Tweaking some parameters may be critical for fixing playback.

Currently, the roc_sender module is sending heavy UDP traffic whether the client is playing audio or not. It can impact the performance of the network when not playing anything and/or lead to unnecessary charges. That traffic is seen as redundant in the network, seeing as it does not lead to anything being played. Unless the sender module is unloaded manually, there is no way to stop the traffic. The redundant traffic precludes the use of roc over metered connections without prior access to the Pulseaudio load-module/unload-module commands, which is greatly impractical.
Ideally, the sender should stop sending any data to the client as soon as playback is stopped.

Currently roc sink input always uses the same output rate.

We need to do the following:

• when the sink input is attached to a sink, we should configure roc receiver to use the sink rate

• when the sink we are connected to changes its rate, we should configure roc receiver to use the new rate

This will require support for dynamic output rate updates.

I'm running pulseaudio on raspbian in pi0.

When I launch pulseaudio --system -vvv I've got a segfault.

I do not know if the problem comes from roc itself, but it does not occur when roc is not started with pulseaudio.

(If I load the module once pulseaudio is running, everything works fine).

• Output from pulseaudio
• backtrace
• system.pa

It should be possible to detect a library and its sources are installed locally without the added need to download libasound, libsndfile, libtool and jsonc. Each step takes time.
It's far quicker to install those via a distribution-based mechanism (deb,rpm etc.) than wait until those download & compile.
Also, compiling pulseaudio isn't strictly necessary either, only configuring it so that config.h is generated.

Hi! Our pulseaudio audio setup over the network is currently very choppy when playing music over the network with Pulseaudio (we use the native TCP-based protocol), so I was looking for something that could be better. I came across roc, and I think UDP and FEC would really help. In the blog post, I read that eventually, a roc plugin might get upstreamed into Pulseaudio (if they accept). Has there been talk with the Pulseaudio people yet? What do they think?

This is my steps for build:

1. unpack roc-toolkit-0.1.5 sources
2. unpack pulseaudio-13.0 sources (same version as installed into system)
3. build with including unpacked pulseaudio source files and linking with system libraries

Got some problems and have questions. Do not know pulseaudio from the inside, so don't be mad:

• hardcoded append /src/.libs/ while searching pulseaudio libraries.
  Pulseaudio installed system-wide already and if set --with-pulseaudio-build-dir=/usr/lib64/pulseaudio/ scons failed.
• Does you really need option --with-pulseaudio-build-dir ? As I can see option --with-libraries has same function. Why not add same search for every LIBPATH as for pa_build_dir? This change do not broke anything and fix this build type(use already installed PA libs + unpacked sources)
• config.h generating. Its confuse me a lot, why we need do this? why this include not guarded by #ifdef HAVE_CONFIG_H?
  If compare with other pulseaudio modules we can found what config.h.in was provided by developers(but there are only with minimal defines)

After some research I found minimal needs for successful compilation pulseaudio modules:

1. #define PACKAGE

2. #define PACKAGE_VERSION "X.Y.Z"
   same as pulseaudio sources version? Scons already have ROC_PULSE_VERSION so there is no problem here?

3. #define HAVE_ATOMIC_BUILTINS only if compiler support __sync_bool_compare_and_swap().
   Its needed because if not set this on x64_86 platform (from src/pulsecore/atomic.h:320)

#elif defined(__GNUC__) && (defined(__amd64__) || defined(__x86_64__))   

#warn "The native atomic operations implementation for AMD64 has not been tested thoroughly. libatomic_ops is known to not work properly on AMD64 and your gcc version is too old for the gcc-builtin atomic ops support. You have three options now: test the native atomic operations implementation for AMD64, fix libatomic_ops, or upgrade your GCC."

I think this is for old compilers from 2008. Today stable gcc and clang do not understand #warn directive, compiler get error and abort compilation. The problem here only #warn directive, replacing #warn by #warning fix this(needed only for x86_64).
Best way is check if all compilers on all platforms have this feature and add static define if possible.

4. #include <sys/socket.h>
   always needed by pulseaudio core

pulseaudio-13.0/src/pulsecore/core-util.h:295:58: error: unknown type name 'socklen_t'; did you mean '__socklen_t'?
int pa_accept_cloexec(int sockfd, struct sockaddr *addr, socklen_t *addrlen);

With this you do not need run configure on pulseaudio sources anymore.

Hi there! I'm trying to get roc running on a raspberry pi (with 64bit arm).

I've used the rocstreaming/toolchain-aarch64-linux-gnu container image to cross-compile

Inside the toolchain container, I used the cmake command cmake .. -DHOST=aarch64-linux-gnu -DPULSEAUDIO_VERSION=14.2

Then I copied the built module-roc-sink.so and module-roc-sink-input.so to /usr/lib/pulse-14.2/modules/ on my raspberry pi.

Then I configured default.pa with : load-module module-roc-sink remote_ip=<some ip>, and performed a pulse audio restart.

This resulted in:

Dec 26 08:56:53 dev1 pulseaudio[2070]: E: [pulseaudio] ltdl-bind-now.c: Failed to open module /usr/lib/pulse-14.2/modules/module-roc-sink.so: /usr/lib/pulse-14.2/modules/module-roc-sink.so: undefined symbol: pthread_atfork

I've looked through CMakelists.txt, but don't see anything related to pthreads. Any tips would be much appreciated.

Hello evryone. I dont know is this a bug or feature but it puts me in trouble :). When i use another audio source on my local coumputer, Roc server is closes the session. When i restart my local pulseaudio it connect again but if i dont use roc sink it closes again. This is my log:

@gavv This is extension of roc-streaming/roc-toolkit#446

I was packaged roc-toolkit-pulse (rock-toolkit with pulseaudio module) for debian based distros (ubuntu) , you can see at here : roc-toolkit-pulse and want to publish at Launchpad as PPA.
But the problem is, to build with pulseaudio module roc-toolkit need to download necessory 3rd party sources, like pulseaudio, libtool etc. and from the launchpad build environment doesn't have any external internet connection so that they that can be downloaded. you can see, the buildlog, I have explicitly check with ping, wget, curl without success. Later I discovered another issue on launchpad itself which confirm my suspect : Launchpad issue

Now the question is how to solve ? So if we self contained every 3rd party sources that will be needed to build with pulseaudio but this will make a high maintained package and we don't want that right ? Now what ?

So, Can we introduce a option like --with-openfec-includes (which is for openfec) for pulseaudio also ? This make launchpad build sucessfull as we can get the pulseaduio headers from libpulse-dev this package. Or this pulseaudio module creation should be leave for the pulseaudio side ? Or should I drop this package for pulseaudio module ?

Hi,

I'm trying to build against Pulseaudio 13.99.1, however I'm having issues with that. Tried on master and on develop. It doesn't seem to have that same issue with pulseaudio 13.0

I'm running the build with scons -Q --enable-pulseaudio-modules --build-3rdparty=openfec,pulseaudio:13.99.1 | tee build.log

I have attached build.log

Thanks
build.log

module-suspend-on-idle from PulseAudio 4.0 suspends Roc sink when it stays idle for some time (no sink inputs connected to it) and resumes when a new sink input appears. For some reason, the process of resuming takes pretty much time, up to 5 seconds.

I wasn't able to reproduce it with module-suspend-on-idle from PulseAudio 11.1. On that version, PulseAudio never suspends Roc sink.
