ну без vaapiparse_h264 можно и обойтись
gst-launch-1.0 -f filesrc location=1.MTS ! tsdemux ! h264parse ! vaapidecode ! queue ! videorate ! video/x-raw,framerate=10/1 ! videoscale ! video/x-raw, width=480,height=240 ! vaapiencode_h264 ! h264parse ! progressreport ! avimux ! filesink location=out.avi
но vaapiencode_h264 не хочет работать так что его надо заменить на x264enc, может это бага самого gst-vaapi.
У самого x264enc есть куча свойств, мож там можно подкрутить и скорость будет еще лучше, типа x264enc speed-preset=ultrafast
плюс еще имеет апааратное декодирование
так что
