Excuse me guys, this seems to be a related topic to my own issues, i have a question to ask. recently i met a problem which is similar to the problem mentioned in this article(
http://www.videoconverterfactory.com/tips/vlc-unable-mrl.html), and it is also about VLC is unable to open the mrl. I downloaded the software it recommended and what bothered me is that it asked me to choose an output encoder for the original mp4 video. H264 and MPEG4, which one to choose, do you have any ideas? Thank you!
