• FFMPEG (BASH) Trying to record stream from IP camera, getting really bad framerates and random stuttering in video

  12 février 2017, par user2419553

  I'm trying to record an .asf from my IP camera using FFMPEG to save it as an .mp4 file every 15 minutes. The stream coming from the camera is variable, but averages at around 10 FPS. However, when I watch the output mp4, the framerate is much lower, and there is often stuttering, random frame skips, and sometimes the video freezes and doesn't play (on VLC player).

  Is there any way I can make the recording smoother and/or have less stuttering?

  Here is the code that I use:

  ffmpeg -i http://USER:PASSWORD@IP:PORT/videostream.asf -r 10 -vcodec copy -an -t 900 /root/Record/"$(date +"%Y_%m_%d %I.%M %p")".mp4
  

  Any help would be appreciated.

  12 février 2017, par Brian_wu

  I use the Flash media encoder to send the video stream which captured by camera, and receive the video stream by my windows phone. I got the sample form https://github.com/Microsoft/FFmpegInterop. I compiled the FFMPEG dll and this sample code can run successfully. I can receive the video from my phohe, but the latency is about 6 seconds. what should I do to cut down the latency?

  Thank you!
