I added wildcards of * through the instruction in hopes that it would convert all files within a folder, but it errors out. I found online information about FFMPEG and an instruction line that someone used that is a 2 part conversion, where the MP4 is converted into an AVI file and then AVI file converted to a AMV, but haven't been able to get it to run properly. I might just send this thing back and get a refund, but if converting the MP4 files to AMV isn't troublesome I might keep it and just convert files for it and run it with AMV files, that is if I can find a way to convert them successfully. AMV … more on AMV format here if curious about that format, and its really great that this format is a Chinese Proprietary Format from what I read online and no documentation exists for it however 'Documentation for this format is not publicly available, but Dobrica Pavlinušić reverse engineered the format to produce a Perl-based decoder and Pavlinušić, Tom Van Braeckel and Vladimir Voroshilov produced a version of FFmpeg that works on AMV files.' : MP4 encoded files and requires videos to be converted to. Looking online I found out that this player is a MP4 player that requires a AMV file format and so it wont run. Bought what I thought was a good deal this MP3/MP4 player on amazon, but to my surprise there are MP4 players out there that don't handle the MP4 format.
