• Script timing with FFMPEG and PHP

  23 juin 2014, par egekhter

  I’m running into a very strange bug.

  Here’s my command console output :

  ffmpeg -i /transcodes/original/883_1000_1403436916_00001.MTS -y -vcodec libx264 -tune zerolatency -

  I’ve tried adding sleep(5) after :

          exec($cmd, $out, $ret);

  to give the script time to move the moov atom to the front before uploading the local file to s3 and then deleting the local file, but it is not 100% reliable.

  Any ideas ?

• call url when conversion completes in ffmpeg

  22 juin 2014, par user2875761

  I am using ffmpeg to convert as background operation. In front using dotnet (web app) to send a video to ffmpeg for conversion. Conversion is done in background. When conversion is completed then url is called from ffmpeg to update database values for sent video. This is working fine for small files. But when i send a big file for e.g. 600MB or 1 GB+ then video is converted but url is not called. And my value in database doesn’t change.

  Is there way to set maximum time to respond from ffmpeg ? Or is there any other way to do it ?

• Adaptive nmls filters matlab python [closed]

  1er juin 2012, par user1314738

  I am interested in removing noise in audio from mike for reatime audio streaming using ffmpeg.

  As I get some background noise while I pass the recorded stream I am interested in removing this noise before I encode the stream the stream.

  There are few issues :-

  1.as i need to this in real time for audio streaming I cannot use Matlab TOOLBOX filters !
  so please suggest other audio processing platforms I can use for the purpose.
  If that is in python it would be really good.

  2.through ffmpeg I can link the alsa sound card using :-

  $ ffmpeg -i hw:0:0 -acodec............... rtp//255:130:40 and stream on rtp.

  but when I will be filtering the sound from mic before it is being used by the ffmpeg, i am bit confused about the syntax for the input to the ffmpeg encoder for rtp streaming.

  would it be fine to use some sort of pipe-lined buffer in between ?But the issue of real time stream and time sync between streaming and filtering still haunts.

  Please help me out in selecting right platform for filtering the audio stream and it's integration with ffmpeg encoder for real time streaming.
