dont kn开发者_JS百科ow whats the problem is but the other format files are succesfully converted with this command. The .wmv files failed...this is a windows media file is that the issue with this or my command is not the one I want to use for this

Please put your ideas please. thanks

It sounds like you may be using an encrypted WMV file. FFMPEG doesn't support decoding of DRM encrypted WMV files.
