Tested on a Raspberry Pi 4B with
Raspbian Buster Lite 2020-02-13 updated on 2020-03-26.
Updates done with sudo apt update && sudo apt full-upgrade && sudo reboot.
With the raspi you should be connected to your local network and to your audio output (earphone, amplifier etc). First you can check your audio output with this small audio file ...
You need a client that can connect to MPD and tell it what to play.
The simplest is the command line client mpc that can run on the Raspberry Pi. After installing it, you would do something like:
$ mpc add http://184.108.40.206:8000/radio1rock64
$ mpc play
The URL to add will of course be different - it will be the address you set up in Icecast for your ...
I did some more reading, and don't think your approach will ever function as desired. Miguel Grinberg's article here outlines how to achieve Raspberry Pi camera streaming to Flask, and provides several useful examples. A simple, complete (non-Pi camera) program is provided which shows the use of a generator function and a multi-part response type to achieve ...
If you want realtime html5 audio on the receiver side, I would definitely recommend a streaming audio solution. CPU, network and memory load is probably much less compared with the solution you described.
Icecast in combination with Jack for streaming audio seems a good solution at first sight. Icecast is well documented and works fine for audio output. ...
Normally if both Ethernet and Wifi are capable of supplying an internet connection to the Raspberry Pi the one with the lowest metric (independent of the internet speed) will be the one used by the Pi to get the internet (In my personal experience eth0 always gets the lowest metric). If you want to check the metrics type route -n you would see something like ...
There's no way to do this without using an external converter.
The BCM2837 chip doesn't support an HD-SDI formatted output, which is fundamentally different to an HDMI formatted output. There's no way to passively convert between the two, so you'll need to use some kind of active external device to run the conversion.
There's a complete walkthrough here on using VLC to capture and stream the desktop of a PC to a second machine. At the time of writing there is a bug in versions subsequent to 2.1.5 which prevent this from working. Install 2.1.5 from here first. It may be necessary to tweak the settings provided there to reduce the video stream resolution and/or quality to ...
It took me weeks to get a workable solution and in the process I read hundreds of webpages with ideas, instructions and software to download.
Finally I was able to reject 90% of it and come up with a relatively simple solution.
Kodi -> Alsa -> avconv -> ezstream -> Icecast2 -> Sonos
I've only tried this with OSMC v2015.12-4 ...
This site isn't made for "which works best for my requirements" as this is highly subjective and likely to change, but a couple of alternatives are:
Volumio - mpd-based, web interface, supports queuing and has a browser interface
RuneAudio - also mpd-based, web interface, based on same code as Volumio but with different features (I use this one)
Both these ...
To fully support video/audio or music from your i device the best thing out there currently is XBMC or better known for Raspberry as RaspBMC
You can install RaspBMC by using the Pi foundations NOOB's installer.
Its pretty simple, once its installed, requires network access, everything else is enabled via the BMC GUI.
Then in RaspBMC you need to enable ...
Audio only on Raspbian. I have done this before with shairport and it worked very well with audio streaming.
Before we can install shairport we need to get a few dependencies.
sudo apt-get update
sudo apt-get upgrade
sudo apt-get install git libao-dev libssl-dev libcrypt-openssl-rsa-perl libio-socket-inet6-perl libwww-perl avahi-utils libmodule-build-perl
In my case (debian stretch + rpi3b+) this has fixed an issue:
sudo apt install libjpeg8
The problem maybe is that some of the libraries are renamed in Stretch, I think.
You could also try to do the following manually if the libraries are still missing:
sudo ln -s libbrcmEGL.so libEGL.so
sudo ln -s libbrcmGLESv2.so libGLESv2.so
There exist some projects out there to achieve something like what you want. Volumio is an example of that. Another one is RuneAudio.
Depending on where you want to store your music, I would suggest you review the official documentation to understand how to connect an external storage device to the Raspberry Pi.
I think the big challenges here will be to ...
It's a complicated project. You should take it to some parts. It's my suggestion and would be happy if other experts improve it.
Anyone can buy a domain name. To do so, you visit a domain name registrar, such as GoDaddy or Namecheap, key in the domain you want to buy, and pay a fee. You can't buy just any domain, of course only one that isn't ...
There are different ways to listen internet radio streams.
MPD : Music Player Daemon,
mpc add http://rdshout.turkuvazgroup.net:7000
After build the python program;
echo "Romantik Radyo, http://rdshout.turkuvazgroup.net:7000/listen....
I used the uv4l driver + streaming option, I only required one connection for streaming through a website.
This tutorial worked for me
uv4l --driver raspicam --auto-video_nr --width 640 --height 480, seems to work smoother/faster than the default in the tutorial :)
I can't say I know anything about Spotify so I'll leave that part for someone else. For streaming audio to an Internet radio you'll need a DLNA server (most "Internet capable" radios that I'm aware of act as DLNA clients). A couple of decent choices are MediaTomb and miniDLNA; these are both packaged for Raspbian so installing them is trivial with apt.
You don't need to use v4l2 to capture sound through PulseAudio.
First of all, find the correct device for pulseAudio. If you're using PulseAudio as a daemon, run this command at the command line:
pacmd list-sources | awk '/name:.+\.monitor/'
You should get output such as:
There are probably several alternatives to accomplish what you want, but one possibility is to use MPD running in a "server" raspberry pi (which may or may not have its own speaker) with audio output through pulseaudio, and then use pulseaudio to broadcast synchronized audio to your LAN over RTP to client machines connected to speakers, wirelessly or not.
Any thing that hangs/kills the Pi outright sounds like power issues.
Power issues on the Pi are often not consistent e.g. the Pi will operate without issue for minutes, hours, days, etc. Before failing.
Please unplug everything and check the power test points.
Its also worth noting that USB power plugs often fail to supply the require 5v EVEN if they are ...
I've been looking into this for quite some time, and the short answer is no.
There are if's and but's, and if you don't want to pay for software, the answer is still no, because:
Pipelight can't be installed on ARM devices, and The Raspberry is an ARM device.
(Will Pipelight work on a Raspberry Pi?)
Netflix still won't officially support Linux, since they ...
You might want to look into wifibroadcast which uses off-the-shelf WiFi hardware :
Why normal wifi is a bad choice for FPV applications
Association: Video transmitter and receiver need to be associated. If one device looses association (for example due to too weak signal strength) the video transmission stops instantly.
Error-free transmission: ...
I think you should try one of two things. Firstly if you want low latency, you should ditch the USB approach which has more latency then one of these GPIO header based sound cards. This can take you from 3 ms down to 0.5 ms in ALSA latency. Now you have to worry about network latency.
For network latency, you can also ditch the server and go directly for a ...
Yes, you can use command line tools to play internet radio streams.
I have used omxplayer to play internet radio streams with no NDMI/video head.
I created certain shell scripts for station choices like Jazz, pop, etc. I would ssh into the "headless" box and start/stop playing.
You can improve by invoking shell scripts via GPIO buttons.
So, I went home and tried the new command with success. The only issue now is some buffering on the YouTube side, which is out of the scope of this question. The below command works fine, replace "REMOVED" with your YouTube channel ID.
sudo /opt/vc/bin/raspivid -o - -t 0 -fps 15 -h 720 -w 1280 -rot 270 | /usr/src/ffmpeg/ffmpeg -ar 44100 -ac 2 -acodec ...
Really, really, really unlikely. For starters, you are talking about two cameras, which presumably are going to be attached to the USB ports, and then a wifi adapter as well on the same bus (since the Pi 3's built in is 150 Mbps); in theory it should allow for this, but in reality I've never seen anyone claim that it gets much beyond 50 MB/s all told, and ...
No on every count I think. It's just not enough of a machine to pull off 4K video at usable frame rates.
The Pi camera module relies on hardware H.264 compression on the main Pi board to get the raw image capture down to a manageable size. It can't keep up with that amount of data at a usable (>24 fps) frame rate. Neither can the network controller or the ...
I am using simple HTTP protocol to connect to my RPi. So, if you can have the IP of your PI, it will work.
On RPi, am running this python service. I am planning to add more security to this later. But for now, in a mini setup, this works. I have even developed an android application around it(find it in my blog series for YOUPICAST).
from flask import ...
I am new at this and software/ operating systems and anything programming are far from my strong points but I managed to stumble along and get Netlix to work. I will explain as best I can as I worked on this on and off for a day and a half – getting bits and pieces from different sites and moving forward a step at a time. . One of the problems that I was ...
