not yet... i am afraid

Well..

Running the most recent driver code I plugged the device in.
It threw off the naming of my PCI cards on reboot. I wrote a udev rule to set the name, but it doesn't change the value of the kernel number.

I blacklisted hdpvr and am now modprobing it in rc.local.

Upon first launch in SageTV I went to configure the device, and inputs are note selectable in the screen. Tailing the log, the only thing I see is:

Sun 8/10 6:28:04.085 setUI(sage.b1@1af4db4[Setup Wizard - Capture Device InputSelect]) histIdx=9 uiHistory=[sage.b1@eeeb48[Main Menu], sage.b1@18baf24[Setup Menu], sage.b1@63278e[Setup Wizard - Summary Page], sage.b1@53bfb7[Setup Wizard - Capture Device Select], sage.b1@1af4db4[Setup Wizard - Capture Device InputSelect], sage.b1@eeeb48[Main Menu], sage.b1@18baf24[Setup Menu], sage.b1@63278e[Setup Wizard - Summary Page], sage.b1@53bfb7[Setup Wizard - Capture Device Select], sage.b1@1af4db4[Setup Wizard - Capture Device InputSelect]]

Note: Looks like SageTV is written by sailors..

v4l2-ctl --device=/dev/video3 -I --get-audio-input
Video input : 0 (Component)
Audio input : 0 (RCA back)

Anyone have any thoughts?

I see in your sig you are running 64 bit linux, In order to get sage running I'm sure you already went through the process of getting 32 bit java and the required libs for sage setup, you will need a one line patch to the hd-pvr driver to make it work with 32 bit apps when it is compiled for a 64 bit kernel,

add the following line:

.compat_ioctl = v4l_compat_ioctl32,

to the file linux/drivers/media/video/hdpvr/hdpvr-video.c
to the bottom of the hdpvr_fops struct near line 611

and recompile/reload the hdpvr module

Let me know if that works ( I wont be able to test the new sage support for hdpvr until the middle of next week ) and I'll try to get it added to the hd-pvr driver upstream source

[bcjenkins]

Added it to:

static const struct file_operations hdpvr_fops = {
        .owner          = THIS_MODULE,
        .open           = hdpvr_open,
        .release        = hdpvr_release,
        .flush          = hdpvr_flush,
        .read           = hdpvr_read,
        .poll           = hdpvr_poll,
        .ioctl          = hdpvr_ioctl,
        .compat_ioctl   = v4l_compat_ioctl32,
};

That did the trick. I set a recording up and will check it out after the movie.

Thanks

The stream records and plays back on an HD Extender, but it isn't tuning channels. I think it is partially failing:

Here's the corresponding dmesg output as well:

I sent it in, but I think I'll switch back to network encoder mode for now.

That actually does look like some more 32bit <-> 64 bit problems, i dont see VIDIOC_S_AUDIO or VIDIOC_S_EXT_CTRL in compat_ioctl32.c

but VIDIOC_ENCODER_CMD should definetely be working..

Would be so nice if the sage guys could just get sage for linux recompiled for 64 bit......

[trueno]

as near as I can tell, VIDIOC_S_AUDIO, VIDIOC_S_EXT_CTRLS, VIDIOC_ENCODER_CMD need to be added to v4l_compat_ioctl32 in video/compat_ioctl32.c hd-pvr seems to be the first v4l2 driver that needs them which is why they havent been in there before. I will add them and test tonight

[bcjenkins]

cool, these are the same errors I see with using hvr-1600s

[trueno]

Hrm, i cant even get my sage server past the setup wizard with the hdpvr driver

after selecting component on the video0 device in the setup wizard, I get a "There was a Capture Error in playback. Details: ERROR (647,0x6e): There was a problem setting up software audio compression.

and in the sage log:

Nothing in dmesg,

How did you get yours past the setup wizard?

[trueno]

OK, got it working, also squashed 2 of those missing 32 bit wrapper ioctls, still working on the last one

[trueno]

It would seem that placeshifter cannot play the video output by the hd-pvr? I just get a black screen. Using the 6.4.7 placeshifter for mac...

Interestingly mplayer for mac crashes trying to play a sample file catted from the hddvr device, and I thought mplayer was used by placeshifter to actually display video..

[bcjenkins]

It is actually ffmpeg. I don't think FFMpeg is capable of playing this back yet, easily. The HD extender can play the files back without issue though.

I don't wait for the video to render. Just click component and move forward.

I'd be interested in that patch.

Thanks,

B

[trueno]

I'll send it along as soon as I figure out the last ioctl (which looks to be a huge PITA). Should be this evening..

[trueno]

How in the heck do you get sagetv to use the spdif audio input (input 2 via v4l2-ctl --device=/dev/video0 --set-audio-input=2)

Sage seems to set it to Audio input : 0 (RCA back)
on startup, and I don't see anything obvious in Sage.properties to override it.. ugh

[bcjenkins]

I don't have access to my server right now, but take a look in the Sage.properties file at the mmc/encoders section.

B

[trueno]

OK, here is the patch that enables hdpvr to work fully under 64 bit kernels with SageTV, it will also silence anyone seeing dmesg errors about VIDIOC_S_AUDIO, VIDIOC_ENCODER_CMD, and VIDIOC_S_EXT_CTRLS

please test!

[bcjenkins]

Patch applied and works on my HVR1600s. Will test HDPVR later. THANK YOU VERY MUCH.

[trueno]

Happy to help!

Quick question, My extenders seem to freeze (they still respond, but video is frozen and has to be restarted) when changing channels recorded via the hd-pvr, everything works fine if I hit stop, and then change channels via the guide, but If I just key in a new channel number while watching another, it seems to freeze a second after the channel change. Are you seeing anything like this? (Latest extender beta firmware)
