[linux-dvb] Analog card with Hardware MPEG2 Enc

[linux-dvb] Analog card with Hardware MPEG2 Enc

[Frederic CAND]

Hi all,

I'm looking for a good PCI card, supporting Analog input (Composite, 
S-Video, Pal/Secam Tuner) and providing MPEG2/TS.

We were using KNC1 TVStation DVR cards until now (w/ saa6752hs chip) on 
the servers we build but we have to change (card status is "end of 
life") and are looking for similar cards.

Does anybody have a hint if such a card exist or not ?

Hardware MPEG2 encoding (TS encapsulation) is an important matter for 
us, to avoid having Software MPEG2 encoding.

Kind regards.

Frederic, I remember you have contributed to saa7134 empress development
previously.

Currently, after lots of code changes without any testers, empress
devices have been always very rare, the support is broken and I try to
track down last working status.

Did some testing with an unsupported card recently, has also DVB-T, and
I get everything to work except the encoder.

What kernel version does still work for you?

There is also the Behold M6 Extra now.
http://www.ixbt.com/monitor/behold-m6-extra.shtml

But this one fails, reported by Anton, even on 2.6.18, which seems to me
the last kernel most likely still functional.

I have tried on a Creatix CTX946. (saa7134 card=12 works,except encoder)
http://www.creatix.de/produkte/multimedia/ctx946.htm

But I don't get a valid format setup, which very likely is caused by the
card is not hacked/correctly_configured yet.

Beside ivtv, the cx88 driver has also lots of cards with mpeg encoder,
so called blackbird design, but from what I hear the pvr150 and similar
are for sure well supported.

Thanks,
Hermann

Actually, since recently we were still using kernel 2.6.9, with an old 
v4l snapshot (20050426).

But, due to some changes, we had to change kernel version, and use 
2.6.16.29. Still, to avoid too many changes to occur at the same time, 
we wanted to use the same snapshot. We did some minor adaptations for it 
to compile against 2.6.16.29.
However, it's working with our same old (but fastly running to its end 
of life) KNC1 TV Station DVR  based on saa7134, saa6752hs and tda9887.

Thanks for these links. Do you know if the chipsets used are running to 
their end of life or not ?

Yeah, but our requirements are not just MPEG2 Hardware encoding, but 
MPEG2/TS Hardware encoding (MPEG2/PS would be painful for us). How can 
we know this prior to buying cards and check ?
We'll be trying the HVR 1300 soon, however.

thanks for the report, i might find a starting point from here.

Unfortunately not, but all the devices mentioned are on a similar level
for my view, means decoder chips and tuners are compatible in the same
row like MK3, MK4, MK5 and saa7134, saa7135 and as long in production
probably still available.

I'm just scratching that stuff for debug, and I'm not even aware of such
a restriction and it is long time ago I looked a little into it.

Maybe Hans, Steve or Mike can give you better recommendations.

Thanks,
Hermann
