A container is something like avi or mkv that holds the video and audio
streams, but I don't think that is your issue.

I'm not familiar with winffm or vlv. If you want us to help, then you have
to give more information (and be careful of typing--did you mean vlc?)

What do you mean you can't use it.

What file are you trying to convert? If you put it on the web somewhere
where one of us could download it, we may be able to convert it for you,
(though I don't have a Windows 95 machine around to test it with.)

What happens if you have a video called myvideo.mp4 and run

ffmpeg -i myvideo.mp4 myvideo.avi

Does it create myvideo.avi?

What do you get if you run

ffprobe myvideo.mp4 (Look for the 0:0 and 0:1 to see what type of codec
they're using.) Something like

Stream #0:0(und): Video: hevc (Main) (hev1 / 0x31766568), yuv420p(tv),
720x404, 136 kb/s, 25 fps, 25 tbr, 12800 tbn, 25 tbc (default)

(For the video. That one is hevc, libx265 which some distributions,
including LinuxMint, won't play)

(Also look for Stream 0:1)

If you have a video that DOES work on Windows95 copy it to your Linux
machine and run that ffprobe command on it and see the names it gives for
0:0 and 0:1.

A sample video would be very useful. If you could put it online somewhere
that we could look at it, we might be able to give more help.
