  • Thread Safety of LibAv/FFMpeg ?

    14 septembre 2022, par user71512

    Is LibAV/FFMpeg thread safe ? For example. Could I read from a file using AVFormatContext* in one thread and decode the read packet it in another with simple additions of mutexes or is the thread safetyness of the library a "don't know don't care" type deal ? I know that libav has basic support for encoder threads but I'm trying more of a blackbox type approach where I break it up into multiple threads (Source -> Decoder -> Filter -> Encoder -> Sink) and trying to understand the complications of such.

    


    Anyone with any experience with ffmpeg and threads and would like to chime in with any other info pertinent to this would also be greatly appreciated.

  • How to use callback function in ffmpeg

    9 septembre 2014, par chesschi
    static int interrupt_cb(void *ctx)

    I understand that many of the functions provided by the ffmpeg libraries are blocking. In order to control the blocking function to timeout, we can assign a callback function to interrupt_callback.

    For example, the avformat_open_input may take 1 second to complete. If I set a timer for 500 milliseconds, will it never be able to connect to the RTSP server and return non-zero value ?

    What is the optimal value for setting this timeout ? What will these blocking functions behave when the timeout value is too small ?

    What is the best approach to use this callback function ?
