• Capturing stream that has multiple frames

  22 mai 2016, par cheese5505

  I’m trying to capture a stream that has multiple "frames" (not sure that’s what you would call it but it has multiple 5 second streams inside of it) with FFmpeg and saving to file. When I put it into Quicktime player and play it works fine, however when I put it into FFmpeg and review the final file it seems that the audio and video are out of sync and the video frequently stops. I think this may be because it is stopping to switch to the new 5 second video but i’m not sure. This is the command I am using :

  ffmpeg \
  
      -v 9 \
  
      -loglevel 99 \
  
      -y \
  
      -re \
  
      -hwaccel auto \
  
      -threads 4 \
  
      -user-agent "Mozilla/5.0 (iPhone; U; CPU iPhone OS 3_0 like Mac OS X; en-us) AppleWebKit/528.18 (KHTML, like Gecko) Version/4.0 Mobile/7A341 Safari/528.16" \
  
      -i "url here" \
  
      -ac 2 \
  
      -strict -2 \
  
      -c:a aac \
  
      test.mov

  In the FFmpeg log this frequently happens :

  frame=  242 fps=102 q=29.0 size=     252kB time=00:00:06.33 bitrate= 325.9kbits/

• How to record the http live streaming from an IP Cam

  26 novembre 2012, par abhishek

  I have created the application in which the client can view the ip camera which is giving
  an http live stream of MJPEG using this link
  Android ICS and MJPEG using AsyncTask

  Now i want the user to record the video into its memory card .
  I have googled for a while and the only two approaches which came in my mind :-

  1. Either i keep storing the jpeg images and when user clicks stop recording then i
     somehow clip all the images as to provide a 3GP video or some other file format.
     But i don't know how to create the video from all the images and will this be an efficient
     approach or not.

  2. Or i do ffmpeg and in this case i will have to deal with NDK and it seems to be a longer
     path which may lead to nowhere :P

  So is FFMPEG a better option ? If yes please share some links or is the first option better.
  Thanks in advance
