Cannot convert ogv to mp4

[ghost]

I tried to convert an ogv file (from RecordMyDesktop) to mp4 without luck. It crashes with the error: "Conversion of out.mp4 to Generic Computer H.264 failed! Reason: Unable to construct pipeline! could not link videotee to queueX" (X changes every time I run the conversion).

I tried running arista-transcoder from the command line and this is what I got:

I know a guide to convert OGV to MP4, AVI, WMV, MKV, FLV, MP3, WAV, AAC, M4A, etc at: http://www.faasoft.com/articles/ogv-converter.html

It also helps you convert other video formats to OGV format.

I use iDealshare VideoGo to convert OGV to MP4 or convert MP4 back to OGV. Here is the step by step guide https://www.idealshare.net/video-converter/ogv-converter-for-mac-windows.html It has both Mac and Windows version. It also helps to directly play, edit ogv files. It can convert between various video and audio formats like OGV, MP4, AVI, MOV, WMV, MPG, H.265, OGG, MKV, VOB, FLV, WebM etc.
