blast's Introduction

BLAST

Cast your Linux audio to DLNA receivers

You need pactl, parec and ffmpeg executables/dependencies on your system to run Blast.

If you have all that then you can launch blast and it looks like this when you run it:

[user@user blast]$ ./blast 
----------

There are also -debug and -headers flags if you want to inspect your DLNA device. Also, -log to inspect what parec and ffmpeg are doing.

Tips and tricks

If you choose blast.monitor as a source, you can send apps' audio to it (in pavucotrol or whatever applet you use) without streaming entire the desktop audio

If none of the built-in codecs presets satisfy you, you can specify your own with -mime and -format. For example: -mime audio/ac3 -format ac3, -mime audio/opus -format opus, -mime "audio/x-caf" -format caf or -mime "audio/mpeg" -format mp2
You can change audio features with -rate, -bits and -channels, e.g. blast -rate 48000 -bits 24 -channels 1

Building

You need the go and go-tools toolchain, also git

then execute:

git clone https://github.com/ugjka/blast
cd blast
go build

now you can run blast with:

[user@user blast]$ ./blast

Bins

Prebuilt Linux binaries are available on the releases page

Why not use pulseaudio-dlna?

This is for pipewire-pulse users.

Caveats

You need to allow port 9000 from LAN for the DLNA receiver to be able to access the HTTP stream, you can change it with -port flag
blast monitor sink may not be visible in the pulse control applet unless you enable virtual streams

Feature: Allow streaming specific programs / audio to dlna

I was using pulseaudio-dlna with pavucontrol for some years and was very happy that with blast something actively developed was working out of the box for me too. 👍

What I am missing in blast is that I can only direct all audio to my stereo and not select per application or output. For instance with pulseaudio-dlna/pavucontrol I m able to say e.g. music playing via vlc or ncmpcpp should go to my stereo but audio from firefox still via my computer's own speakers.

Would be great if you consider that as a future feature :)

Support for AVTransport 2

Hello,

is it difficult to add support for AVTransport 2?

Thank you!

bit-perfect streaming

Hi @ugjka

Thanks for the blast! First WORKING solution to stream audio from PipeWire to a remote DLNA renderer! Awesome!!!

I have the following enhancement request:

I have configured blast to stream losslessly by option -usewav and proper -rate and -bits values. That means that blast is sending the stream without any compression, but always resampling everything to upfront fixed samplerate/depth, unless you play the stream of the same samplerate/depth...

I am wondering if it would be possible to create a new option/options for blast, so then blast is simply only re-sending the stream of the same bitsdepth and samplerate as it receives at the moment, without any resampling.
For instance a new option -bitperfect, or extending existing options to accept "auto" values, like -rate auto and -bits auto.

I would appreciate your feedback.

Error on play_media with UPnP Error 714 received: Illegal MIME-Type

if this is correct I found here you may add .mp3/mime-type:

home-assistant/core#37444

Detect endianess of the dlna device when sending raw lpcm

otherwise there's a high chance of garbled audio with incorrect endianess. See issue #7

Apparently BubbleUPNP on android does this somehow.

For now you have to set -bige flag if your device is big endian

This only seems to matter for lpcm streaming since stuff like wav and flac are little endian by definition

Blast unable to connect to DLNA Player

Hello,
I am trying to use blast with me moodeaudio device. This has always worked with pulseaudio-dlna, but as I am testing pipewire, i stumbled on your solution.

My Problem is this: I seem to be unable to connect to the device.
I Found ticket: Stream to Sonos - Errorcode 714
and the issue seems similar. I downloaded the "dlna-send.zip" and tested with it.
This is the result:

$ ./dlna-send https://ugjka.net/ircradio
