Output to URL

[julienjura]

Hello there !

I'm trying to capture & stream audio to an URL as provided in OBS-Studio. I've just cloned this minimal sample repo, rebuilt obs-studio-node from source, properly updated package.json and ran yarn install/start.

Electron is launching but won't send data to my URL (Icecast server) as set in basic.ini. I end up with the same situation when trying to set settings by myself in function configureOBS() (file obsRecorder.js)

I'm running this sample on a fresh Windows 10 install

Here's my basic.ini :
`[Video]
BaseCX=200
BaseCY=113
OutputCX=200
OutputCY=113
ScaleType=bicubic
FPSCommon=60

[Audio]
SampleRate=44100

[SimpleOutput]
Mode=Simple
VBitrate=2500
StreamEncoder=obs_x264
ABitrate=160
UseAdvanced=false
FilePath=C:\Users\julien\Videos
FileNameWithoutSpace=false
RecQuality=Stream
RecFormat=mp4
MuxerCustom=
RecRB=true
RecRBTime=20

[Output]
Mode=Advanced

[AdvOut]
TrackIndex=1
RecType=FFmpeg
RecTracks=1
FLVTrack=1
FFOutputToFile=false
FFURL=icecast://source:password@url:port/endpoint.ts
FFFormat=mpegts
FFFormatMimeType=video/MP2T
FFExtension=ts
FFVEncoderId=27
FFVEncoder=libx264
FFAEncoderId=86018
FFAEncoder=aac
FFAudioMixes=1
FFVBitrate=25
FFVGOPSize=2
FFIgnoreCompat=true
RescaleRes=1920x1080
RecRescaleRes=1920x1080
FFRescaleRes=140x80
FFABitrate=128
FFMCustom=
FFRescale=true
Encoder=obs_x264
ApplyServiceSettings=true
Rescale=false
RecFilePath=C:\Users\juju\Videos
RecFileNameWithoutSpace=false
RecFormat=flv
RecEncoder=none
RecRescale=false`

Here's my configureOBS() function
`
function configureOBS() {
console.debug('Configuring OBS');
setSetting('Output', 'Mode', 'Advanced');

setSetting('Output', 'TrackIndex', 1);
setSetting('Output', 'RecType', 'FFmpeg');
setSetting('Output', 'RecTracks', 1);
setSetting('Output', 'FLVTrack', 1);
setSetting('Output', 'FFOutputToFile', 0);
setSetting('Output', 'FFURL', 'icecast://source:password@url:port/endpoint.ts');
setSetting('Output', 'FFFormat', 'mpegts');
setSetting('Output', 'FFFormatMimeType', 'video/MP2T');
setSetting('Output', 'FFExtension', 'ts');
setSetting('Output', 'FFVEncoderId', 27);
setSetting('Output', 'FFVEncoder', 'libx264');
setSetting('Output', 'FFAEncoderId', 86018);
setSetting('Output', 'FFAEncoder', 'aac');
setSetting('Output', 'FFAudioMixes', 1);
setSetting('Output', 'FFVBitrate', 25);
setSetting('Output', 'FFVGOPSize', 2);
setSetting('Output', 'FFIgnoreCompat', 1);
setSetting('Output', 'RescaleRes', '1920x1080');
setSetting('Output', 'FFRescaleRes', '140x80');
setSetting('Output', 'FFABitrate', '140x80');
setSetting('Output', 'FFRescale', 1);

setSetting('Video', 'FPSCommon', 60);

console.debug('OBS Configured');
}
`

Congrats for all this wonderfull piece of software !
Best regards

Everything is working on OBS-Studio, i just want to replicate the correct settings in an test electron app through obs-studio-node

[Envek]

Don't change ini files directly, instead change configuration programmatically, as shown here:

obs-studio-node-example/obsRecorder.js

Lines 69 to 77 in e626868

	function configureOBS() {
	console.debug('Configuring OBS');
	setSetting('Output', 'Mode', 'Advanced');
	const availableEncoders = getAvailableValues('Output', 'Recording', 'RecEncoder');
	setSetting('Output', 'RecEncoder', availableEncoders.slice(-1)[0] || 'x264');
	setSetting('Output', 'RecFilePath', path.join(__dirname, 'videos'));
	setSetting('Output', 'RecFormat', 'mkv');
	setSetting('Output', 'VBitrate', 10000); // 10 Mbps
	setSetting('Video', 'FPSCommon', 60);

Beware though, that API doesn't match configuration files format 1-to-1 and I believe that there is probably no docs for that. So, only trial and error and many experiments in debugger console.

Sorry, I can't help much there, I hadn't explored streaming.

Hi Envek !

I tried this way yet but unsuccessfully. I'va posted my configureOBS() function

I'm using FFmpeg in OBS-Studio, so I tried :
setSetting('Output', 'RecType', 'FFmpeg');

Maybe FFmpeg is a plugin or something else i need to place in specific location ?

I traced encoders returned by
Only these are provided :
const availableEncoders = getAvailableValues('Output', 'Recording', 'RecEncoder');

ENCODERS :
none
obs_x264
obs_qsv11
ffmpeg_nvenc
jim_nvenc

@julienjura Any progress? I was also plagued by the problem of pushing streams to the server, and I didn't know how to set it up because there was no docs.

@julienjura @xiaoyao316 Did you call osn.NodeObs.OBS_service_startStreaming()?

If you get it working, it would be great if you could create a PR to https://github.com/hrueger/obs-studio-node-docs with instructions on how to setup streaming.
