• Capturing video from a MJPEG stream using C++

  16 octobre 2012, par Dídac Pérez

  I would like to capture a MJPEG stream using C++. Which options do I have? I have tried OpenCV with FFMPEG support but icvCreateFileCapture_FFMPEG_p is always returning null (after a few seconds of timeout). May I program a HTTP client by myself?

• Mp4 ( created by concatenating two mp4 using ffmpeg) not playing in html5 video tag

  16 octobre 2012, par enthusiastic

  I am getting trouble to play mp4 file in video tag of html5.

  I have two mp4 files on my server. I use following code.

  This works fine. After that I am concatenating two mp4 using ffmpeg. Code for concatenating as follows.

  exec('ffmpeg -i input1.mp4 -qscale:v 1 intermediate1.mpg');
  exec('ffmpeg -i input2.mp4 -qscale:v 1 intermediate2.mpg');
  exec('cat intermediate1.mpg intermediate2.mpg | ffmpeg -f mpeg -i - -vcodec copy -acodec copy intermediate_all.mpg');
  exec('ffmpeg -y -i intermediate_all.mpg -an -pass 1 -threads 2 $options temp.mp4');
  exec('ffmpeg -y -i intermediate_all.mpg -acodec libfaac -ar 44100 -ab 96k -pass 2 -threads 2 $options temp.mp4');
  exec('qt-faststart temp.mp4 new_output.mp4');
  

  This conversion works good. I can play this file using every player but when I use this converted file in video tag It doesn't work.

  Any help will be appreciated.
