Marton Balint 8d92f59d11 avformat/file: fail for non-numerical arguments to pipe: 
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>.

FFmpeg README

FFmpeg is a collection of libraries and tools to process multimedia content such as audio, video, subtitles and related metadata.

Libraries

  • libavcodec provides implementation of a wider range of codecs.
  • libavformat implements streaming protocols, container formats and basic I/O access.
  • libavutil includes hashers, decompressors and miscellaneous utility functions.
  • libavfilter provides means to alter decoded audio and video through a directed graph of connected filters.
  • libavdevice provides an abstraction to access capture and playback devices.
  • libswresample implements audio mixing and resampling routines.
  • libswscale implements color conversion and scaling routines.

Tools

  • ffmpeg is a command line toolbox to manipulate, convert and stream multimedia content.
  • ffplay is a minimalistic multimedia player.
  • ffprobe is a simple analysis tool to inspect multimedia content.
  • Additional small tools such as aviocat, ismindex and qt-faststart.
