The following commit has been merged in the experimental branch:
commit 81bd4119652ce3911c6604f3421a46c677d6c10f
Author: Stefano Sabatini <stefano.sabatini-lala at poste.it>

    In av_close_input_stream(), flush the packet queue before to actually
    close the stream.
    
    This way the flushed packets can still reference the still unclosed
    format context.
    
    In particular this fixes a spurious error issued when closing the
    video4linux2 buffer in mmap_release_buffer(), which tries to access
    the file descriptor of an already closed file.
