Hello, I wonder if the decoding of DVB with chroma 04:02:02 in Vu + are made by hardwere or softwere? I have a VU + with SOLO2 OpenPLI 3.0, which for me is the best picture at the moment but the channels that use this chroma image does not open. Enjoying the post. Why is it not possible to open stream "MMSH" broadcasts on the net?

In hardware, so there is no way to fix this

Probably the MMSH as MMS and RTSP, are using codecs  WMV/VC1 and vu+ can't handle them.

 

Check If vu+ can play files stored locally with WMV/VC1. If it play files locally then there is a problem with gstreamer most probably.

 

You can find sample wmv videos here.

 

 

In hardware, so there is no way to fix this

 

I think only azbox is capable to open 4:2:2 feeds from enigma2 capable STB's

With respect to 4:2:2 chroma, would then be a limitation of the processors Broadcom, since the use Azbox STi's? Note, I do not speak English so I use the google translator. Sorry if the text sometimes get a little incomprehensible.

But is 4:2:2 available under E2 in AZ?

 

Or must one use Original FW?

Original FW only. The 4:2:2 headers and implementation must be known in order to use in enigma2.

Thanx.

 

For lay people like me, can you explain how come it's "known" in OFW and it isn't in E2 - both are Linux kernels and drivers are from the same company... (OK, kinda "same company"...)???

e2 does not play any role in playing back 4:2:2 video, it's just drivers and hardware.

In lay-man terms - video drivers used with enigma2 have no 4:2:2 functionality implemented.

And from my understanding is that manufacturer still selling their stb with closed source firmware

- enigma2 support is not official.

And my understanding is that the RTi team has/had an inside source, which gave them "everything they needed"... Some of them were boasting about that quite a bit...

 

I suppose, now that they have not succeeded in a number of ways, they may change that story somewhat... :rolleyes: :D

Yeah - we can do that since dm800 era...but why should one buy an enigma2 stb then ?

The real issue there is out there is called IP or copyright. Yes..very expensive.

AZ is using one of the chips capable - the orhers are not even considering using these type of chips.

How many 4:2:2 feeds are out there ? Considering one buys an FTA, this should have been a top priority for mostly all

FTA companies including DM, VUplus etc.. Let`s see things with a different perspective: how many enigma2 boxes have

HW blindscan enabled working today ? (answer: not many).

And the feeds are using it... as it is somehow a protection...

 

When you do feedhunting I suggest you do not use a settop box, but you are using a PC with e.g. a spectrum analyzer as help to to find used frequencies....

I was hoping to use an stb to do blindscan searching ... unless the point is to have all this equipment for specific
 reasons.  For sure nothing can replace a scope. I was not perceiving chroma subsampling as being a protection measure,

but more a quality codec used for transmitting video stream. On north america turf- turbo, dicicipher and dvb-s2 ACM modulation are a protection measure.

You guys in europe only know about dvb-s2 and some highrate signals. (no offence intended - just that it had to be mentioned) :)

Copyright? Is that the stuff that Mierdoch likes breaking if it's other people's and enforcing if it's his own? :rolleyes: :D

 

Aren't some of the newest machines mentioned in the 4:2:2 context? It escapes me which one now...
