Using video module with ffmpeg to convert; how do I display converted files?
Solved this by modifying the custom module. Test if file has been converted, by looking in sites/default/files/videos/converted/nnnn, where nnnn is the File ID of the original file. If not then display the original video file. If conversion completed successfully, then display the converted file from sites/default/files/videos/converted/nnnn. There is only one file in the nnnn directory.
