Hi,
while working on a small test app which repacks the ivtv-PS into a TS, I
received a sample from a cx18-based card. The
TS contains the video PID 301, audio PID 300 and PCR pid 101.
Where do these PIDs come from, are they set by the driver or are they
firmware given?
For analog captures, for which the firmware creates the TS, the firmware
sets them.
That's what I thought. So I will use the same IDs for my conversion of an
ivtv-PS.
Is it possible to change them?
It is not possible to tell the firmware to change them. There are two
documented CX23418 API commands in cx23418.h:
CX18_CPU_SET_VIDEO_PID
CX18_CPU_SET_AUDIO_PID
Unfortunately, I know they do nothing and will always directly return
0x200800ff, which is a CX23418 API error code.
Good to know.
Thanks!
Lars.

Andy
