HD-PVR giving up

Hi all,

Having sorted my SG's and channels, I'm a small step closer to getting liveTV working.

catting /dev/video0 gives perfect results, but playing liveTV thro myth results in lots of audio static and the HD-PVR going in and out of recording mode at about 10 second intervals, accompanied by louder clicks.

Audio is in through s/pdiff, and video is component at 720p, both set as device defaults using module parameters.

I'm not using vdpau yet as I wanted to get one thing sorted at a time so stickin to the default CPU+

Channel change script is set to /bin /true for the moment.

Motorola IP stb turned on first, then hd-pvr and finally the pc. I have manually changed channels since starting the pc and loading the hdpvr module.

System is dual core opteron running at 2.4 GHz per core, 2 GB RAM

Using mythbuntu karmic installed from daily build a few days ago and fully dist-upgraded including Jean-Yves testing repo.

Here's what my backend log says:

Can anyone say what I'm doing wrong?

I have a Motorola 6200 box, and capture HD and SD flawlessly. I had
some very strange results at first, like you.
You HAVE to ensure this is done:
Set the box to only output 720.
Also:
For Motorola STBs, it is also important to set the "4:3 Override" option
to Off or Stretch. For some Motorola STBs, both the aspect ratio
settings and output resolution controls can be found by powering down
the STB and then pressing the Menu button.

This will make a huge difference if you have not already done this.

I use firewire channel changing 6200ch which is also flawless, and
capture sound via rca cables.

Ensure you have permissions on /dev/video as well.

Thanks Mark for both your suggestions. I'm prettuy sure the Motorola is set up properly, using 720p as the output format, and outputting the original format. The only difference being that I'm currently outputting sound over s/pdiff (Ill try RCA during testing tho.

The /dev/video0 permissions I haven't checked. Good point! Do I need r or rw permissions from the mythtv group?

Will try again this evening, as I only had a few seconds yetserday before family took over the tv. Will also look more closely at frontend log, and dmesg.

System is combined BE/FE and 64 bit btw.

Cheers!

Are you sure about that? Myth needs to be able to tell the HD-PVR
what bitrate to record at, etc. I am pretty sure it would need write
privileges on the device.

You could be correct on that for sure. 775 perms and make sure you add modify your groups accordingly.

Thanks for feedback so far.

I`ve done the following:

created udev rule setting:

then:KERNEL=="video0",MODE="0775", SYMLINK+="video"
finally manually changed permissions to 777, just in case.

user:grp is root:video, but both mythuser (user) and mythtv are in video group

Perhaps I should test rca stereo audio capture ->aac next, currently trying s/pdif ->ac3

Any other ideas?

Upgrade the firmware on the HD-PVR. Switch to RCA audio. Stop using

Perhaps I should test rca stereo audio capture ->aac next, currently trying s/pdif ->ac3

Any other ideas?

well that didn`t help much.

Re: HD-PVR giving up [In reply to]

You could try setting the hdpvr_debug level in the kernel level
options to see if dmesg might give you some info.

I just got my hdpvr working last night, and the little I've played
with it it seems to be working quite well. I compiled from the
22-fixes branch which I updated last night. What I learned along the
way (which probably has no bearing on your issue, but you never know -
it might trigger something to try).

If you have SP/DIF selected, but your optical is not hooked up (or you
hooked it to the output instead of the input like I did), the
recording will fail.

The patches mentioned on the wiki page turned out to be very important
for me. Without the patches, It would work until I changed a channel.
Not sure if mythbuntu incorporates these or not.

I have my box set at 720P I believe (I did this a long time ago and
haven't gone back to verify), but the wiki indicates this should no
longer be an issue. I was planning on experimenting this weekend.

I am using VDPAU and haven't tryed without. It was so easy to setup
and worked out of the box. I'm running an i5 (2.66 GHz) and during
live TV I get 1 to 2% CPU usage on one of the CPUs.

Hopefully something will point you in the right direction. Good luck.

Ron

Thanks Ryan and Ron,

Firmware is, I think latest, Set was delivered with 1.5.6, but to make sure I "upgraded" from a doze VM a few weeks back. Once the file is unzipped, it says it's beta, but I think Hauppauge just forgot to rename it.

I now have both RCA and s/pdif connected, so can switch easily between them. One stupid mistake I did find was that I had connected the s/pdif from the computer to the hdpvr input instead of from the tv tuner (because of the way my audio system is set up. I've fixed that now, but still no luck. There does seem to be a problem with the file that is created in tne livetv dir. Looks like the one mythtv is looking for is always a different name from the one that's there. I stop livetv, delete the file, try again, and another file is created with the wrong name. I didn't have time to completely confirm it, so might be a wrong impression. Will write back next time I have time to play with the system...probably towards the end of the week. Sorry about html.

Marius

I just wanted to add my 2 cents in here with my experience with the HD-PVR.
I've been trying to get this working for about 4 weeks (not solid, I have
been using the firewire successfully in the interim). I had a fairly recent
firmware installed out of the box (0x0f), but try as I might using the
information in the HD-PVR wiki, the backend would fail on all recording
attempts. I started over by upgrading the firmware at Hauppaugue web site.
It now sits at 0x12. After re-adding the HD-PVR to the backend, I actually
got a recording to be made with no errors in the log file; however, the
recording itself was unwatchable. The recording would "stutter"; it would
play fine for 2-5 seconds then stop as if it had been paused on a single
frame for 1-2 seconds and then repeat. After searching the recent posts and
finding your post, I decided to go back and change the output of my DCH3200
to 720p (it was at 1080). I had left it at 1080 because, as you pointed
out, the wiki said this step should no longer be required. I am here to say
that when I changed to 720, not only did I get no errors while recording,
but the playback was flawless. So I would say, at least in my case, 720p
output is required.

Thanks Ken,

Interesting what you said about the firmware number and re-adding the hd-pvr. 720p is the only format being output by my cable box, so that's at least one thing that shoudl be correct. I haven't had time to re-check my firmware yet, due to very low WAF, and box being connected to the TV which is in constant evening use by the family.

Next things for me to try (in order), are:
revert again to rca (I somehow messed up even more last time I tried this, but haven't managed to undo the damage yet, so will revert again)
re-install the firmware from a windows VM
double check the permissions and paths in my storage groups
set /dev/video0 permissions to 777
enable vdpau playback (I didn't really want to do this before I had the setup working with cpu+, as it's another unknown, but hey, what can I loose?)
Reinstall the whole sjabang :-(

At the current rate this list will take me several weeks, all in the face of steadily falling WAF, so I really hope one of the first steps does it for me.

Cheers!

Marius

I tried using VDPAU but found it to be not quite stable enough for every day
use. Since I have plenty of CPU power, I have reverted to the HIGH QUALITY
profile which has performed very well. I'm running Ubuntu 9.04 and it
appears that all videox devices are added with the group VIDEO which has rw
access. My mythtv user is a member of the VIDEO group.
I have both the RCA (stereo) and spdif cable connected between the HD-PVR
and the DCH3200. I disconnected the RCA cables and the sound disappeared
(as expected from reading the wiki). I'm still not sure how to set module
level parameters, but maybe someone reading this will offer suggestions or a
link to a web page that describes such.
Anyway, I'm much closer to having it working the way I want than I was a
week ago. Too bad this system can't handle the 1080 input (although I don't
know what my cable provider is actually sending over these channels).

Hi again Ken,

Yes, looks like my permssions were the same as yours to start with (before I changed them to 775). VDPAU I haven't tried yet, as stated earlier, but I'm using the NVidia 190.x driver from JYA's repo.
The kernel level module options are just options lines which you put in a file under /etc/modules.d/ Yopu'll see other files there which you can check for syntax. The options themselves I found in the WIKI (setting default audio and video inputs etc.) I've changed mine back to s/pdif and component now, but will revert to rca/component for the next tests (and in the backend setup).

I only have a 720 TV so am sticking to 720p anyway for now, although cable will spit out a max of 1080i if I ask it to. To be honest I'd rather have the slightly lower res, and not have to bother with the deinterlacing anyway.

Cheers!

Marius

So, some more information on the hdpvr driver. Using ubuntu 9.04, I added a
file called hdpvr.conf to my /etc/modprobe.d/ directory. In it I added the
line:

options hdpvr default_audio_input=2

Then I did a sudo rmmod hdpvr, followed by a modprobe hdpvr.
A cat of the sys entry:

ken [at] mytht:~$ cat /sys/module/hdpvr/parameters/default_audio_input
2

Interestingly, the default value (if there is no hdpvr.conf file) for this
parameter is a three (3) which is not listed in the HD-PVR wiki. I haven't
tested this by unplugging the stereo cables yet, but will try this when I
get home tonight.

If all this pans out, I will attempt to update the wiki with this
information.

...sounds like a frontend that doesn't have enough horsepower to play back
the recording in question. I got a similar result when I tried to play back
a 720p HDPVR recording on an AppleTV.

Depending on your frontend gear, you might want to lock your cable box
into a lower resolution. I had mine at 480p to accomodate my slower
frontends like the AppleTV.

Jedidiah:

Thanks for your feedback. I'm running a Q6600, 2.4Ghz quad core, so I don't
think this is a CPU issue. My OTA recordings at 1080i are rendered fine
without using VDPAU. I believe that the problem is actually in the
recording itself, not in the playback. I transferred a small piece of the
video to a Windows laptop and played it with vlc with the same results. I
haven't played with any of the bitrates available through the v4l-ctl
utility. This may have some impact on the output. I'll try to play with
this later.

OTA, eh? Yes. I have similar problems myself. Anything OTA that has
visible blockiness tends to make the trunk internal player crash. I can
play the recordings back fine with any other player.

HDPVR recordings (assuming you are in the US) are much more system
intensive than OTA recordings. MPEG2 is easy. h264 can be downright hard.

A 2.4GHz CPU is *not* near powerful enough to render HD-PVR recording
via software. If you are using VDPAU it is enough, but if you want to
do it in software you need something like a 3GHz Core 2.

HD-PVRs produce single-sliced H.264 which is very difficult to decode.
OTA (in the US) is done with MPEG2, which is very easy to decode.

If you want to decode high bitrate HD-PVR in software, you need a much
more powerful mythfrontend computer.

Thanks, I stand corrected. After some experimenting I now understand how
much more intensive H264 is to decode than mpeg2 which I guess is why so
much attention has been paid to VDPAU and the NVIDIA driver. Until I got the
HD-PVR working I haven't had to deal with it at all. Just goes to prove the
rule of inverse knowledge ("the less you know about something, the more it
can do").
