    avplay: Add an option for not limiting the input buffer size · 296d0da8
    Martin Storsjö authored
    For reading from normal files on disk, the queue limits for
    demuxed data work fine, but for reading data from realtime
    streams, they mean we're not reading from the input stream
    at all once the queue limit has been reached. For TCP streams,
    this means that writing to the socket from the peer side blocks
    (potentially leading to the peer dropping data), and for UDP
    streams it means that our kernel might drop data.
    
    For some protocols/servers, the server initially sends a
    large burst with data to fill client side buffers, but once
    filled, we should keep reading to avoid dropping data.
    
    For all realtime streams, it IMO makes sense to just buffer
    as much as we get (rather in buffers in avplay.c than in
    OS level buffers). With this option set, the input thread
    should always be blocking waiting for more input data,
    never sleeping waiting for the decoder to consume data.
