Concurrent recordings (multirec) with ffdecsawrapper

[sjuk]

Is there any chance to get concurrent recordings (multirec) with ffdecsawrapper to work?

Without ffdecsawrapper mythtv records multiple streams on the same transponder perfectly. Enabling ffdecsawrapper allows only one recording at the same time. And I have got a dual tuner. As a workaround I've configured ffdecsawrapper only to use one of the two available adapters. So that I can use one for the free to air channels (with multirec on the same transponder), and the other to record encrypted channels (without multirec).

Is there anyone who does multiple recordings with ffdecsawrapper? Is there a configuration option I have to add? Is there a special firmware I need to use?

Multirec works just fine over here . The 'Concurrent FF recordings are NOT allowed' message means that it is not allowed on FF (full featured) cards. So a card that has a chip that does the work of FFdecsawrapper. Nowadays, all dvb cards are of the "Budget" category, so multirec is always enabled.

In mythtv-setup, I always set 'Max recordings' (in recording options) to the maximum of 5.

I have 8 DVB-C tuners in my backend. The only thing that restricts the max number of concurrent recordings is the cpu power and/or the speed of my harddisk. So not FFdecsawrapper.

You may have a driver issue

Thank you for clarifying. I thougt the FF in "Concurrent FF recordings are NOT allowed" stands for "Fucking Fast" as in "FFdecsa" (found that in the docs of the sourcecode).

I don't think it is a driver issue, because without ffdecsawrapper the recordings work nearly perfect (one zero-byte-recording a year). But many thanks for trying.

I've changed my ffdecsawrapper config and raised the max recordings in mythtv-setup from two to four. In a first test I could record two shows and look live tv. (Live tv writes on a ssd, and the recordings are written to a normal 7200 rpm 1gb hd.) I'm very excited about the results in the long run...

Perhaps I have to play with the priority options in mythtv to prevent recording conflicts? Perhaps I have to turn off some of the loggings, to prevent slowing down the hd write velocity? Or perhaps there are some options in ffdecsawrapper to tune performance?

I will let you know if it becomes an issue again.

Many thanks for now

bas-t ... you said you have 8 DVB-C tuners in my backend could you share brand and model or your cards? thanks

In one of my backends I've got 2x TBS 6285 (quad tuners), in the other 3x DVBSky T982 (dual tuners). Both backends run perfectly well. Op 2 apr. 2016 10:19 schreef "rlzar" notifications@github.com:
