正确的 ffmpeg 命令以获取详细的播放列表信息

我有一个播放列表 [ playlist.m3u8]，其中有多个流 [ https://stream1.m3u8, https://stream2.m3u8]，我想获取此播放列表中每个流的更多详细信息。

我尝试运行：

ffmpeg -fflags -loglevel info -re -i playlist.m3u8 -vcodec copy -acodec copy
  • 接收错误： 
    Trailing options were found on the commandline.
playlist.m3u8: Invalid data found when processing input

我该如何写出正确的命令？

  • 我需要获得如下输出：

答案1

只要运行ffmpeg -i playlist.m3u8就可以得到读数。

答案2

这是我得到的： ffmpeg version 4.1.3 Copyright (c) 2000-2019 the FFmpeg developers built with gcc 5.4.0 (Ubuntu 5.4.0-6ubuntu1~16.04.12) 20160609 configuration: --prefix=/home/juraj/ffmpeg_build --pkg-config-flags=--static --extra-cflags=-I/home/juraj/ffmpeg_build/include --extra-ldflags=-L/home/juraj/ffmpeg_build/lib --extra-libs='-lpthread -lm' --bindir=/home/juraj/bin --enable-gpl --enable-libass --enable-libfdk-aac --enable-libfreetype --enable-libmp3lame --enable-libopus --enable-libvorbis --enable-libvpx --enable-libx264 --enable-libx265 --enable-vaapi --enable-nonfree libavutil 56. 22.100 / 56. 22.100 libavcodec 58. 35.100 / 58. 35.100 libavformat 58. 20.100 / 58. 20.100 libavdevice 58. 5.100 / 58. 5.100 libavfilter 7. 40.101 / 7. 40.101 libswscale 5. 3.100 / 5. 3.100 libswresample 3. 3.100 / 3. 3.100 libpostproc 55. 3.100 / 55. 3.100 playlist.m3u8: No such file or directory

我确信该文件和目录存在。我也从正确的目录运行此脚本。我甚至尝试了此文件夹中的其他 Python 脚本，除了这个 ffmpeg 命令之外，一切都很顺利。
