我试过使用和不使用 :1935 端口号，使用 ffmpeg_x64.exe 但没有区别。流密钥是 invalid argument 还是其他？
想通了。 -f 参数用于指定输入格式 dshow，但如果放置在输入和输出之前，此参数也是位置相关的，适用于输入 and/or 输出格式。
所以解决方案是将 -f flv 也添加到输出中：
ffmpeg-N-100616-gca21cb1e36-win64-gpl\bin\ffmpeg.exe -f dshow -i video='screen-capture-recorder':audio='Microphone (VF0700 Live! Cam Ch' -r 24 -s 1920x1080 -qmin 3 -f flv 'rtmp://a.rtmp.youtube.com:1935/live2/the-stream-key'
所以，我们说输入格式是 dshow 放在 -i 标志之前，输出是 flv 放在输出之前（流通道).

简而言之，错误是：

我试过使用和不使用 :1935 端口号，使用 ffmpeg_x64.exe 但没有区别。流密钥是 invalid argument 还是其他？
想通了。 -f 参数用于指定输入格式 dshow，但如果放置在输入和输出之前，此参数也是位置相关的，适用于输入 and/or 输出格式。
所以解决方案是将 -f flv 也添加到输出中：
ffmpeg-N-100616-gca21cb1e36-win64-gpl\bin\ffmpeg.exe -f dshow -i video='screen-capture-recorder':audio='Microphone (VF0700 Live! Cam Ch' -r 24 -s 1920x1080 -qmin 3 -f flv 'rtmp://a.rtmp.youtube.com:1935/live2/the-stream-key'
所以，我们说输入格式是 dshow 放在 -i 标志之前，输出是 flv 放在输出之前（流通道).
