Possible software with support for converting of undf files to mpeg4 file format.
Sometimes VLC (VideoLAN) player makes error message that it does not support "undf" audio or video format. This confuses some users and they try to convert their (usually perfectly fine) media files to something else. This error is prompted when a proper decoder for the video format is not loaded in VLC.
No conversion required. You just need to check for a new version of VLC player or codecs. Sometimes partially downloaded files cause this error, in this case you need to either finish the download in process, or download the file again. You will not find any converter that recognizes "undf" format anyway.
Unfortunately, there is no detailed software record in the database for this conversion.
This conversion entry was verified by us and conversion from undf to mpeg4 was flagged as wrong or not possible.
Usually this happens when the conversion would try to convert different types of data between each other, such as audio to image, or it can't be done because incompatibility between programs, caused by closed file formats, very limited support or by other problems.
