  • Streaming protocol relay without involving codec

    4 décembre 2015, par kiran_g

    I am trying to use libav to relay an RTSP stream. It involves PULLing the stream from an IP camera and then PUSHing to wowza.

    The video encoding in the IP camera stream is h264. To enable h264 in my libav application I need to enable x264. But as x264 is GPL, it will not work with my business plan.

    My questions is whether libav (ffmpeg) can be made to work like a dumb relay which is encoding-agnostic ? so that I dont need to integrate x264 with ffmpeg.

    This SO post says that I can use the "copy" argument, but does that allow me to exclude x264 ?

    BTW, is x264 actually needed by ffmpeg for decoding h264 ? Is x264 only used in encoding ?

    See here for my current code.

  • FFMPEG Multiple Input Output With Lowest CPU Usage

    18 novembre 2015, par Benny Chen

    I’am trying to stream several IP Camera with FFMPEG. For now I run FFMPEG process for each stream like below :

    ffmpeg -fflags nobuffer -i input -c:v libx264 -an -preset ultrafast -y output

    I’d like to made the latency as low as possible, so put nobuffer seems good and made the conversion ultrafast. This will also decrease CPU usage because its lossless conversion.

    Now I have another problem. With several IP camera with can increase in number near future, running several ffmpeg process seems take the CPU usage very high. With just 6 camera, it has roughly took 50% of CPU usage. I plan to use 10-20 Camera.

    I’d like to reduce the CPU usage. I thought can be done by combine all process in single process. I try to find if it is possible in ffmpeg documentation but still can not find it.

    Any solution ?

  • Getting decibel levels from ffmpeg at each point [duplicate]

    20 mai 2021, par Kaushik SA

    I was working on a feature that requires me to identify people talking in a video/audio clip. Basically these intervals will be marked for review later by an auditor.
I plan to use ffmpeg's silencedetect to identify intervals with silence and assume the rest as talking.
Is there a better way to do this since I would have to set a threshold decibel which would prevent me to get whispers,etc. Is there a way to get an audio graph of the audio/video clip where we know the decibel at each point ?
