  1. I have some general questions using ffmpeg to download on Windows xp and Windows 7
    On Windows xp, I can use this code to download a particular video:
    Code:
    ffmpeg -i "Hockey.m3u8" -c copy -bsf:a aac_adtstoasc output.mp4
    This command shows a very simple display of downloading (see screenshot 1)
    However, if I use the same command on Window 7, (with newer version of ffmpeg) I get an error message
    (see screenshot 2)
    Question #1
    Why does the same command not work in Windows 7?

    On Windows 7, I can use any of these commands to download:
    Code:
    ffmpeg -protocol_whitelist "file,http,https,tcp,tls,crypto" -i "Hockey.m3u8" -c copy -bsf:a aac_adtstoasc output.mp4
    Code:
    ffmpeg -protocol_whitelist "file,http,https,tcp,tls,crypto" -i "Hockey.m3u8" -c copy -c:a copy output.mp4
    Code:
    ffmpeg -protocol_whitelist "file,http,https,tcp,tls,crypto" -i "Hockey.m3u8" -c:v copy -c:a copy output.mp4
    All of these seem to yield a complicated command display like (see screenshot 3)
    Question #2
    Is there a simple command using Windows 7 that will make the command display look simple like in Windows xp (each line just shows the frame number, fps, etc, not all those extra lines that are shown in screenshot 3)
    Question #3
    What is the meaning of
    -protocol_whitelist "file,http,https,tcp,tls,crypto"
    and why is it necessary to have this on Windows 7 but not Windows xp?

    Security changes in newer versions of ffmpeg.

    Run the old version of ffmpeg that you use with XP.

    It's not an XP vs. 7 issue. It's an older ffmpeg vs. newer ffmpeg issue.

  3. If I use the older version of ffmpeg (xp version) on Windows 7, will the old ffmpeg download as many videos as the new ffmpeg? I know the latest youtube-dl will download many more videos than the older youtube-dl, so I thought the newer ffmpeg would download more videos than the older ffmpeg.
