• FFMPEG : RTSP re-stream dies randomly

  14 mai 2018, par stevendesu

  I have a security camera streaming RTSP, and I wish to re-stream this to an RTMP ingest server. For now I’m using my laptop as an ffmpeg proxy, but eventually I’ll use a raspberry pi or something similar (cheap/small)

  Here’s the command I’m using (pretty simple) :

  ffmpeg -i rtsp://@10.0.0.16:554/1/h264major -c:v libx264 -c:a none -f flv rtmp://output/camera_stream

  This works but after a minute or two the stream dies. Here’s the output :

  The camera is pretty cheap (from China) so it’s likely I’m getting bad data from it or it’s cutting out for a few seconds at a time. Ideally I would need ffmpeg to handle this well (ignore bad data, wait as long as necessary for good data to resume encoding)

  Using ffplay to check out the RTSP stream, I get output like the following :

  Then eventually the video just freezes. The first time it froze after around 5 minutes, but I wasn’t able to say definitively if it froze the instant 44 packets were dropped or if it froze randomly later. So the second time I stared intently.... for 21 minutes. Then I got bored of it not freezing, turned to pet my cat, and when I looked back 15 seconds later it was frozen. I think it only breaks when no one is watching it.

  What I can say definitively is :

  • While running normally, M-V hovers around 0 (anywhere between -0.01 and +0.01)
  • Once frozen, M-V begins to count down into negative numbers without stopping - although at a rate slower than -1 per second
  • While running normally, aq is 0KB and vq is a positive number (I think it was 30KB or so ?)
  • Once frozen, vq is also 0KB

  It’s a really cheap camera with a crummy power supply that goes out if you breathe on it, so it’s likely the camera is going temporarily offline during this time — but I’d like ffmpeg to wait out a timeout and resume streaming when it sees the camera again.

• FFMPEG fails with only two input frames

  3 mars 2019, par JeffThompson

  I’d like to use ffmpeg’s great frame interpolation to blend two images. I get great results when testing with about a dozen frames, but when only using two it finishes immediately and I get a video file that can’t be opened.

  My command :

  ffmpeg -y -r 24 -pattern_type glob -i "TestFrames/*[0-1].png" -pix_fmt yuv420p -filter:v "minterpolate='mi_mode=mci:mc_mode=aobmc:me_mode=bidir:vsbmc=1:fps=1024'" -vsync 2 8.mp4

  (Why fps=1024 ? I wanted to generate a a bunch of frames between the two images, so I plan to later separate the resulting video into separate images.)

• ffmpeg saves only first frame

  2 juin 2021, par DuDa

  I generated rotating pictures in Python and now I want to create an animation from it using ffmpeg. But the generated video includes only the first frame (viewed in VLC) and is way to small (half the size of one png) for all 36 pictures. What am I doing wrong ? Thank you.
