Hi everybody,
first test results from me:
As expected, the double "ivtv_msleep_timeout(300, 1);" in ivtv-streams.c
increases the time for stopping/starting a stream. I removed the first call
and it still works fine.
@ Mike:
Previously I suggested to add a msleep(300) in state_eval_decoder_run
(pvrusb2-hdw.c), after calling pvr2_decoder_enable(hdw,!0).
With the change from Andy I now have again sporadic black screens with my
saa7115-based PVRUSB2. So I moved the sleep directly into "static int
pvr2_decoder_enable":

Funny- this seems to work, no more black screens appeared.
The remaining questions are in my opinion:
1.)
What is Hans opinion about the changes, especially the move of the 300ms sleep
from "after disabling the digitizer" to "after enabling it" ?
2.)
Do we want to keep disabling the digitizer during the
CX2341X_ENC_INITIALIZE_INPUT call in case the digitizer is a cx25840x ?
It seems to be necessary only for the saa7115.
Note: The cx88-blackbird-driver does also no disabling/enabling of the
digitizer (cx2388x) when doing this firmware call.
3.)
Does Andys Patch solve the tinny audio problem for Argus (who originally
posted the problem and a different solution in the ivtv-devel list). I add him
in cc.
Greets and Happy New Year
