  • Detecting frozen frames in video file using ffmpeg or similar

    16 décembre 2015, par jakkolwiek

    I’m trying to find a way to analyze couple of video files (mov) in order to find files with frozen frames or black screens appearing. I know that using simple command with ffmpeg returns the start/stop point and duration of black screens, unfortunately I can’t find any solution for frozen frames. The video files are rather small and definitely not high quality, but I need to distinguish the broken files apart from good ones. The thing is, it has to be to use as a simple shell command or library in order to use it with Java, Python, Ruby or similar. Any advice is much appreciated !

  • Why does ffmpeg have bigger latency on dark images ?

    19 novembre 2017, par doodoroma

    I have a c# application to stream real camera images using ffmpeg. The input images are in raw, 8-bit gray-scale format. I created an ffmpeg stream using the standard input to feed the images and send the output packages to websocket clients.

    I start an external ffmpeg process using this config :

    -f rawvideo -pixel_format gray -video_size " + camera.Width.ToString() + "x" + camera.Height.ToString() + " -framerate 25 -i - -f mpeg1video -b:v 512k -s 320x240 -

    Typical image size is 1040*1392 pixels

    I display the stream on the browser, using jsmpeg library

    This works with a reasonable latency ( 500ms on localhost), but when the camera image is really dark (black image), the latency is extremely big ( 2-3 seconds on localhost). When there is something bright on the image again after a black period, it takes 2-3 seconds to "synchronize".

    I was thinking that black images are really easy to compress and will generate really small packages, jsmpeg has almost no information to display and wait until a complete data package arrives, but I couldn’t prove my theory.

    I played with ffmpeg parameters like bitrate and fps but nothing has changed.

    Is there any settings which I could try ?
