On the PDF attached on the Setup screen it is mentioning:
"Transcoding can be started when there is no corresponding channel recordings.
When transcoding, both PIP and analog video ouputs are disabled."
Is it effectively taking control on the audio-video threads ?
A thread is a software pump so to speak - copying buffers from source to destination.
If at this level the HW is not capable of managing all the internal buffers...then that is not very nice - maybe it is a limitation in HW.
And off course there is a lot of quirks you need to figure out so that no racing conditions are developed in the driver area.
