  • Ffmpeg gentle stop sending [closed]

    31 mars 2023, par Ли Шеньшунь

    Good day. I'm trying to do a simple video sending and receiving on two computers that are on the same network. Video simulates streaming (video conference for example). I want to use ffmpeg but have run into a number of difficulties.
I start with two simple scripts :
Sender machine

    


    ffmpeg -re -i input_file.mp4 -c copy -f mpegts udp://192.168.2.10:1234


    


    recipient machine :

    


    ffmpeg -i udp://192.168.2.10:1234 -c copy save_video.mp4


    


    I got 2 questions :

    


      

    1. Is there a way to correctly end video reception when the sender does not send anything else ?

      2. 


    


    The receive command works by waiting indefinitely. If the sender is still sending video and at this moment interrupt the receiver with ctrl+c, then the video is saved correctly. If the sender is finished, then after that, to stop, you need to use ctrl + c twice and the video is "broken", because. does not open apparently due to damage to the meta-data or codecs.

    


    I'm aware of options like using timeout, or saving to mkv format, they really work. But setting a specific number of seconds is problematic, and simply killing a process does not look very nice.

    


      

    1. Is the -re switch enough to simulate a "webcam" from a video file ? I heard that ffmpeg buffers packets in case of loss and can send them later later. I need to send it as it is, if there are any problems, then we lose the package forever. The -flush_packets key, as I understand it, is for writing to a file, but not when sending over the network.

      2. 


    


  • fftools/ffmpeg : stop using AVStream.nb_frames in do_video_stats()

    16 décembre 2021, par Anton Khirnov
    fftools/ffmpeg : stop using AVStream.nb_frames in do_video_stats()

    Its use for muxing is not documented, in practice it is incremented per
    
each packet successfully passed to the muxer's write_packet(). Since
    
there is a lot of indirection between ffmpeg receiving a packet from the
    
encoder and it actually being written (e.g. bitstream filters, the
    
interleaving queue), using nb_frames here is incorrect.
    

    Add a new counter for packets received from encoder instead.
