Not every channel/transponder tuned. #12

Closed GoogleCodeExporter closed 9 years ago

GoogleCodeExporter commented 9 years ago 
I have this scenario:

1. VTUNERD compiled for ar71xx platform, openwrt netgear router. On this router 
DVB services worsk - tested mumudvb, scan-s2, szap-s2.

2. VTUNERC compiled for i686 platform. ubuntu 10.04.3 distribution.

1 Made 10 channels test file (various channels from HB 13") and im zapping with 
szap-s2 directly on router with vtuner - on every channel i got "FE_HAS_LOCK" 
that means channel tuned succesully. After this im starting VTUNERD on router 
and VTUNERC ond the deskop i try to tune channel 1 - no way - not tuned, trying 
tune channel 2 - OK - now back to channel 1 - tuned!... strange goes 2,3,4 
ok.... channel 5 not... 6 not... 7 ok 8 not 9 ok 10 ok... when im on 9 and 
switch to 5 6 or 8 channels works!!! strange. this is reprocudable. 

channels list for reference attached.

I changed driver to older and all zapping via vtunerc works...

Strange.

May be so timing issue? 

The vtuner subsystem adds some additional delays on every ioctl call, what can 
be disliked by some applications.

Anyway, if old driver works, then it looks like your bug is driver specific.

Seems like driver bug.

But if you need to reopen, don't hesitate to do it.
