[vdr] Re: CAM Aston 1.05 workaround

[Patrick Gueneau <pgueneau@wanadoo.fr>]

Hello,

I have done some testing based on Antonino VDR patch.

It seems we have to force tuner status change to force CAM reset after 
going from one Audio track to another.

BTW, I never succeeded in recording 2 audio tracks at the same time 
using ASTON CAM.
It also seems the new Pilotime Canal+ Recorder/Decoder can only record 
1 audio track at the same time.
May be it is a SECA2 constraint/limitation.


Now the problem with VDR is there is no patch Klauss can merge in VDR 
code to support this particular ASTON CAM constraint.

Maybe Klauss can use some #if conditional hacks to enable SECA2 Audio 
track handling.

That means :

- Antonino patch to define only one audio track in CAM CaPmt structure.
- change in cDvbDevice::SetAudiotrackDevice method to force tuner 
thread to set a new CaPmt (setting tunerStatus to tsTuned seems to be 
OK)
- misc code to deal with recording (lock audio during recording) and 
limit SetPid to current audio track.


I am working on these mods to test Canal+ recording but I have to work 
on VDR 1.2 code to understand how different it is from version 1.04 I 
know better.

Patrick.
