transcoding .ts files from tvheadend. At the moment the best is using Gstreamer
because I can handle best performace. With Gssreamer I can transcode 1 minute
.ts FHD video file to .mkv 480x270 in 30 secons which is in my opinion very
good performance and I want to keep it.<o:p></o:p></span></font></p>
