ffmpeg : mp4 conversion - no video in output file
Hello,
i have a few files downloaded from youtube as mp4. They play just fine in vlc.
I'd like to convert them either into avi or mkv. And my naive attempts to leverage ffmpeg have failed.
in all attempts i get an audio track in a fil, but no video.
Please advise what am doing wrong.
Thank you

That file name is a mess. It has commas, parenthesis, % chars in it.
Start with a file_name.mp4 FileName.mp4 or similar.
Quote:
I'd like to convert them either into avi or mkv
If all that you want to do is change containers:
Code:
ffmpeg -i file.mp4 -c:a copy -c:v copy file.avi
Depending on what you start with that will probably be h264 video and aac audio.
If you want just the audio from it
Code:
ffmpeg -i file.mp4 -vn -c:a copy file.m4a
If you look, utube vids come in different formats. You can get just the
audio, or the video resolution and size that you want from the start.
From an example:
