Twitch stream with FFMpeg using multiple audio inputs [on hold]
23 décembre 2014, par Josh RaymondI’m using the following script to try and stream my linux desktop to Twitch.tv, I have the stream working, but I want to throw in 2 audio inputs into the stream (one for the game, and one for my mic)
Here’s the script
#! /bin/bash
INRES="1900x600"
OUTRES="800x600"
INAUD="pulse"
FPS="25
STREAM_KEY=$(cat ~/.twitch_key)
STREAM_URL="rtmp://live.twitch.tv/app/$STREAM_KEY"
ffmpeg \
-f alsa -ac 2 -i "$INAUD" \
-f x11grab -s "$INRES" -r "$FPS" -i :0.0+1280,0 \
-vcodec libx264 -s "$OUTRES" -pix_fmt yuv420p \
-acodec libmp3lame -threads 6 -qscale 5 -b 64KB \
-f flv -ar 44100 "$STREAM_URL"I use Pulseaudio and have pavucontrol, if that matters. The game would be on "Build-in Audio Analog Stereo" and the mic is from the recording device "Webcam C110 Analog Mono"
Thanks in advance.

C# .net mvc Process return encoding progress (FFMpeg) to client initiated with ajax
19 décembre 2014, par user1585895I am using FFMpeg to encode wav to mp3s, and on completion download the final .zip to the client.
All works great, and I can Debug.WriteLine the progress of the encoding, but I would like to return _percentage back to the client to do some UI updates based on the value of _percentage and if all encoding is done, Im not sure how to approach this.
My thinking is as follows :
- ajax post to CreateAndDownloadAlbum(List trackIds, int productId)
- loop through List and create a new Process, run
— parse StdError to get encoding percentage in myProcess_ErrorData(object source, DataReceivedEventArgs e)
— send _percentage value at timed intervals back to CreateAndDownloadAlbum
— update UI based on value of _percentage, when all is complete break and call public ActionResult SendFileDownload()
Any input would be great.
Thanks !
front end AJAX call to post list of file Ids to download
var data = $('#downloadAlbum').serialize();
$.ajax({
url: "/Admin/CreateAndDownloadAlbum",
method: "POST",
data: data,
dataType: 'json',
success: function(result) {
// wait here for _percentage
// if not 100, call again to get new _percentage value
// if 100, update UI, move to next file being encoded
// if all encoding is complete, call SendFileDownload() in controller
}
});then the controller code
