h264 interlaced content shows doubled length (and consequently breaks
seeking) due to how the backend counts frames. It assumed one frame/slice
when in fact, with interlaced content, it's one field/slice thus doubling
all counts. A quick fix to ensure this is indeed the case is to halve all
the values in the seek table after the recording is finished.

Correct me if I'm wrong, but this is about 95% of what's needed? Given the
frame number, all that would need doing is to keep track of the last frame
number and increment only if the current is different. However, not knowing
the spec, I don't know if fields can come out of order over different
fields.

I had the linux driver working on my original HD-PVR but had to send it
back. When the new one came it had a 1.0b disk which I installed on
Windows and it seems to work.

But I didn't see the warning about 1.0b until after it was installed.
I reinstalled
the old driver 1.0... will that get me back to the 1.0 firmware?

I tried that but now a:

cat /dev/video0 > foo.ts

produces only an empty file. setting hdpvr_debug 1 shows it calling
start_streaming but nothing after that. Ctl-c shows calls stop_streaming...
Unplugging/replugging behaves but no data in the file. Anyone have any
ideas?

If you have one of the "new" HD-PVRs, you must use firmware 1.0B.

The warning you quoted was basically because 1.0B has not been well
tested. It should work, however.

mine was also sent back, not sure what version the new one came
back with but it works just fine.
I wasnt about to plug it into a windows machine in case it
did try to load firemware. so Im not sure which one it has
nor sure how to check under linux.

If it says "rev c1" on the bottom, that is a first generation. Not
sure what the second generation say.

Re: [mythtv-commits] Ticket #5443: HD-PVR support [In reply to]

the sticker says rev 2 but I dont know if that means its just
the "with fan" version of the hardware or if its also got
the 1.0b firmware loaded.

My new one is "rev C2". Anyone have this revision working
with the 1.0b firmware with the Linux driver?

/var/log/messages:

But the file is empty.

If anyone has ideas on where to try additional debug output let me know.

Is this using Myth or doing a "cat /dev/videoX > test.ts" ?

You are using component input with the rear RCA audio jacks?

Most people using this box under Linux can be found on the hdpvr IRC
channel (on the FreeNode server). Your best chance of getting help,
is there.

Both. But when Myth didn't seem to work I went back to cat.
With my old unit a cat /dev/video0 > test.ts just worked.
I didn't even have to set any options with v4l2-ctl.

> You are using component input with the rear RCA audio jacks?

Yes.

So I unplugged and replugged and saw this:

Jul 1 09:02:47 devbox kernel: hdpvr: INFO get_video_info: get video
info returned: 5, 00 00 00 00 00
Jul 1 09:02:47 devbox kernel: hdpvr: INFO hdpvr_device_init: no valid
video signal or device init failed

It was tuned to an SD channel at that point.

I then unplugged, tuned to a 1080i channel on the
settop box and replugged and see this:

Jul 1 09:35:22 devbox kernel: hdpvr: INFO get_video_info: get video
info returned: 5, 80 07 38 04 1e
...
Jul 1 09:35:56 devbox kernel: hdpvr: INFO start_streaming: video
signal: 1920x1080[at]30hz

And it is working for this channel. Anyway I was probably just
testing an HD channel on my old unit so it is probably working as well
as before.
