[linux-dvb] hvr4000-s2api + QAM_AUTO

[Christophe Thommeret]

Hi Steve,

I've managed to add S2 support to kaffeine, so it can scan and zap.
However, i have a little problem with DVB-S:
Before tuning to S2, S channels tune well with QAM_AUTO.
But after having tuned to S2 channels, i can no more lock on S ones until i 
set modulation to QPSK insteed of QAM_AUTO for these S channels.
Is this known?

Hi Christophe,
do you mean FEC_AUTO? There is a note in the comments in cx24116.c about
FEC_AUTO working for QPSK but not for S2 (8PSK or NBC-QPSK). 
Look for "Especially, no auto detect when in S2 mode."

Hope I'm not misunderstanding your question.

I'd be very happy to try out your patch for Kaffeine and give feedback if you are
ready to share it.

Regards,
Hans

Other users aren't seeing this, so it could be something odd with 
Kaffeine. Please collect dmesg output and email me, it should be obvious 
what's going on with this.

Thanks,

Steve

Good to know, but i really mean QAM_AUTO

Sure, here it is (patch against current svn 
http://websvn.kde.org/branches/extragear/kde3/multimedia/)

Atm, s2api is only used for S/S2.

P.S.
In order to play H264/HD with kaffeine/xine, you need a fairly recent ffmpeg 
and xine compiled with --with-external-ffmpeg configure option. (and of 
course a quite strong cpu, unlike my old athlon-xp-2600 :)
However, you can still record and/or broadcast without this update.

Success! Many thanks Christophe.

With the following:
HVR4000 card
S2API + multifrontend patch (hg clone http://linuxtv.org/hg/~stoth/s2-mfe)
ffmpeg from SVN
xine-lib from mercurial (compiled with --with-external-ffmpeg)
Kaffeine from SVN + Christophe's S2API patch

Scanning to find channels and tuning are working in Kaffeine for  DVB-T, DVB-S and DVB-S2.
S/S2 tuning and scanning is with S2API.

My CPU (3ghz core 2 quad) is fast enough to show live HD video so I can watch HD channels
live inside Kaffeine, or record to disk and watch afterwards. ASTRA HD+ and ANIXE HD are
good. ARTE HD throws some errors and stutters a bit. Simul HD can crash Kaffeine.

I enabled the two lines in dvbstream.cpp which set modulation to QPSK instead of
QAM_AUTO for DVB-S.

Settings: number of xine threads >= 4, de-interlacing(CTRL-I) at minimum (is it useful for HD ?
I don't know). The load isn't always distributed well across the 4 cpus -- it can max out one
of them sometimes, with the others almost idle. Perhaps this can be improved.

Regards,
Hans

Excellent news.

Christophe, thanks for helping with Kaffeine :)

A suggestion:  Write your arte-HD streams to disk, instead of
trying to decode them real-time.

If for some reason your CPU isn't quite fast enough, you can
later decode the arte-HD streams and see if the artifacts you
are observing are still present.

If there's some encoder parameter being used by arte-HD that is
not yet properly supported, then later you should be able to
decode that stream flawlessly (this is the case for me with ITV-HD
recorded before mplayer could properly de-interlace it).

Alternatively, I noticed myself that the occasional recordings I
made for the first couple days of the recent IFA EinsFestival 
showcase showed problems in `mplayer', while those recordings
made later were as flawless as those made half a year ago, so I
do not rule out tweaking of the encoders used...

Hi Barry, thanks for the suggestion. 

I have checked this : Arte HD recordings I have just made with Kaffeine
play perfectly with mplayer (svn yesterday). So there's no basic
problem with my CPU power or with support for the stream by ffmpeg. 
When played back in kaffeine/xinelib the sound is missing or jittery.

Simul HD is a different story -- recordings play ok for a few tens of seconds
in mplayer (with some errors "warning: first frame is no keyframe") until a
hard crash with error "Internal error, picture buffer overflow" from mplayer.
In kaffeine it the recordings play with jittery sound and then crash at exactly the
same points with the same error.

Any ideas anyone?

Regards,
Hans

could you play with ffplay from svn and download somewhere the sample with 10 MB size (I will try to play)

So, you see this also. This was my original report, and why i introduced this 
fix.

Yes for 1080i but not for 720p.

Perhaps, but this is ffmpeg stuff.

Btw, while cx24116 single-frontend seems pretty stable, the mfe driver is not 
here. As soon as i switch to dvb-t, the cx24116 firmware crashes (at least 
seems so: ~"Firmware doen't respond .." ) and is reloaded on next S/S2 zap, 
and after a while, the dvb-t signal appears more and more noisy. I have to 
unload/reload the modules to cure this.

Does anyone have any info about Arte HD or Simul HD?

Yes. The multithreaded decoding does spread the load well for some HD channels.

Oh. I haven't seen any problems like that or heard it reported before.
I am using firmware version 1.23.86.1. Which version are you using?

Can you load dvb_core like this:

	dvb_core dvb_powerdown_on_sleep=0

This will stop access to the cx24116 when the bus is in use by the cx22702.

This is a workaround until a better fix is found. Tell me if it solves it
for you, Thanks.

Unfortunately, no.
I will try with newer firmware, as soon as i find it.


Btw:
Darron, all these Eutelsat spec compliant msleep are already implemented by 
applications, so adding it in driver just increases diseqc delay :)
I've removed all these in driver and diseqc works fine.

after my bug report and sample from SimulHD Michael Niedermayer from ffmpeg-team has fixed this bug in ffh264
in 15413 revision. Could you test please
