FLV file converter in Linux

Using "mencoder" to create "flv" from "avi" video format files

Many website nowdays are using swf and flv file formats to play videos hosted on there site or sites, it's advantage is clear in that the file itself is often in comparison to regular video format files smaller and easier to upload so the the site is able to hold and run more video content with much less bandwidth than would normally be required.

#> mencoder -oac copy -ovc lavc -o video.avi video.flv

This one below was also found to work, the "avi" file here was created and generated with an "mov" extension but really it was and "avi" file, it is composed of a number of jpg images stringed together and "mp3" audio file this was created using the Open Video Editor. The file created by Open Movie Editor generated as I say a file with an "mov" there are three options to render the output file but the extension remains regardless of choice. We then used the command below to convert the file to an "flv" format file, this worked rather well and the audio was intact, however the generated file and movie image size was larger than intended so more options may be needed to the command line to adjust video size.

># mencoder source.avi -oac copy -ovc lavc -o destination.flv
