Tvheadend

The data from one mux are processed in this way:

- hw input thread - dst: buffer1
  - input thread - src: buffer1 - [descrambling] - TS packet split to queues
  - queue threads (DVR, streaming)

So yes, the 'input thread' is the bottleneck in this case. But if you like to descramble 7 channels from one mux, I would buy more appropriate hw. ARM CPUs are a bit slow for this.

Yeah i thought so, didnt have any problems with 6 channels for a long time, when i put on the 7th things started to have lagging.

The arm cpu should be good for descr 6x4 channels if all cores were used. So I dont think its that slow again =)

So what I need todo is to split the input into spts'es before tvheadend recieve them that way each channels decode will have its own thread ?

Do you also use optimized dvbcsa library for ARM? It might be much faster on ARM.

Yes ofcause :)
