Description
I have created a new profile "Autodetect from 720p" it works fantastic when using mpeg4. However, what I'm after is a lossless transcoding to remove adds after editing a recording. The error I'm getting "Unknown video codec: H.264" seems to be the issue. As mentioned in the beginning, If I change it to mpeg4 rather than lossless, works.
