To convert an .ogv video file to an .avi video file in Linux, you can use the ffmpeg command-line tool. Here’s an example of how to perform the conversion:
ffmpeg -i input.ogv -c:v mpeg4 -b:v 1000k -c:a libmp3lame -b:a 128k output.avi
In this example, -i input.ogv specifies the input file, -c:v mpeg4 sets the video codec to MPEG-4, -b:v 1000k sets the video bitrate to 1000 kilobits per second, -c:a libmp3lame sets the audio codec to MP3, and -b:a 128k sets the audio bitrate to 128 kilobits per second. The final argument output.avi specifies the output file.
Note that the exact parameters you use for ffmpeg will depend on your desired output quality, file size, and compatibility requirements.
