    avformat/file: fail for non-numerical arguments to pipe: · 8d92f59d
    Marton Balint authored
    Before this patch, the implementation of pipe: inputs/outputs would
    silently fall back to stdin/stdout for any argument not successfully
    parsed by strtol().
    
    This patch introduces an explicit error for any non-numerical arguments,
    which should avoid user confusion as in #10977.
    
    New behavior:
    
    $ cat /tmp/video.mkv | ./ffmpeg -i pipe:aa -acodec copy -vcodec copy -f matroska pipe:1 | cat >/tmp/out.mkv
    
    [pipe @ 0x5618c7bcf740] Non-numerical argument "aa" to pipe:
    [in#0 @ 0x5618c7bced00] Error opening input: Invalid argument
    Error opening input file pipe:aa.
    Error opening input files: Invalid argument
    
    Based on the patch of Nils Goroll <nils.goroll@uplex.de>.
