[linux-dvb] setting demuxer buffer size

[sf <sf@b-i-t.de>]

Hello again,

I tried to set the demuxer buffer size to 188*2^n bytes (n from 1 to 
4096) but the ioctl always fails.

My understanding is that the demuxer buffer is a plain kernel memory 
buffer and not in any way depending on hardware. Is this correct?

If I have the sequence

1. open
2. set pes filter
3. start filter

at what point do I have to set the buffer size?

Regards
