Meteor Spawn_Child_Process for FFMpeg [duplicate]
2 mars 2013, par user2009114Hi I am trying to use Meteor and javascript (Node) to spawn an ffmpeg transcoding event and then stream it live through HTML5 video tags. However, though I can get it working with node.js it seems to hang on the Meteor server and not stream anything though it does seem to be transcoding okay. It appears that the transcoding thread hangs up the server, or is not even a different thread at all ? I am pasting the relevant server side code followed by the client code calling it. One JQuery function calls the transcoding process and the PollForPlaylist is called from the video tags by the hls/. Any help would be much appreciated in solving this. I am wondering if there is a meteor function which I can call to spawn a thread for the ffmpeg function ? Or maybe there is another way to push data to the video tag through jQuery ?
var spawnNewProcess = function(file, playlistPath) {
var outputUrlPrefix = '/segment/';
var args = ['-i', file, '-async', '1', '-acodec', 'libmp3lame', '-b:a', 128 + 'k', '-vf', 'scale=min(' + targetWidth + '\\, iw):-1', '-b:v', videoBitrate + 'k', '-ar', '44100', '-ac', '2', '-vcodec', 'libx264', '-x264opts', 'level=3.0', '-profile:v', 'baseline', '-preset:v' ,'superfast', '-threads', '0', '-flags', '-global_header', '-map', '0', '-f', 'segment', '-segment_time', '10', '-segment_list', 'stream.m3u8', '-segment_format', 'mpegts', '-segment_list_flags', 'live', 'stream%05d.ts'];
