It is going to be some time for me to get to it.

Workaround: Set a recording and then go watch it.

The ideal would be a git commit. Otherwise, a unified diff would be fine.

As I recall, this is highly dependent on the hardware and the network,
which is why the application can override the default settings.

Depending on what you use for booting your mvpmc you may need to update
it - specifically the 'mediamvp_booter.pl' script requires a patch due
to a newer version of Perl being installed under 9.10.

As for mythtv, it's been solid. I'm just switching to HD (using
Hauppauge HD-PVR) so I'm in the initial testing with it (so my use of
mvpmc will be drawing to a close soon - it's been absolutely GREAT).

Re: libcmyth git questions

So, if you use <atomic.h> it should search the system headers first then
local headers (current directory). If you use "atomic.h" it should search
the current directory first then system headers. The trouble is, in this
case, 'atomic.h' is neither local (it is in a different directory) nor,
strictly, the system header <atomic.h> that it needs to pull in for MIPS.
This means you can't use the search rules to differentiate. It is simply
going to blindly follow whatever the -I<dir> options specify in order.

That is why the naming is unfortunate.

He was talking about the latter, I believe. We should not be defining variables in the
middle of functions, as you stated.

architectures I was building for at the time.

Depending on whether you use

#include <file.h>

or

#include "file.h"

varies the search algorithm looking for the file. Are we sure we are using the right
variant mechanism here?

One discussion of the differences is here:
http://publib.boulder.ibm.com/infocenter/comphelp/v8v101/index.jsp?topic=/com.ibm.xlcpp8a.doc/compiler/ref/tuinclud1.htm

I'm sure there are others. The gcc man page probably covers it as well!

Thank you. However, I'm going to stop now. My goal was to learn, and I have learned enough to satisfy myself atm. The next steps would require too much time/effort for me. So I am not going to make any further effort to use this device with mvpmc.

I'm very satisfied with the amount I learned about dhcp, tftp, mvpmc, etc. and I feel very confident about running my rev H box now. So that's a great outcome and I appreciate all the help. :D

It's standard but runs on ports 16867/16868

SageTV does use mvp.bin but remember that comes from dhcp I could
setup my config to load mvp.bin as easily as dongle.bin.mvpmc and it
loads fine on a stock Hauppauge MVP too.

So the Hauppauge and SageTV server software includes a bootp service?
That would make sense, as it could be ran on a network with DHCP already
running and not interfere.

Presumably the bootp client built-in to the MVP bootloader firmware is
standards compliant, otherwise it wouldn't work with the bootp services
built-in to most DHCP services that run on Linux.

Given that bootp servers are available independent of DHCP servers, I
wonder why the mvpmc howtos didn't recommend installing that, rather
than supplanting the DHCP server on the LAN, which seems to be a
down-side for many users.

> ...so this still points to dhcp problems.

Yes, to the extend that dhcpd is the one responding to the bootp packet.
I checked out the ISC DHCP website and didn't see anything indicating
you need to do anything special to enable bootp functionality. (Their
FAQ mentions something you need to do for v2.2 era Linux kernels, but
that's pretty old and probably outdated.) I couldn't put my hands on a
man page quickly, but ran across this page:

http://www.netbsd.org/docs/network/netboot/dhcpd.html

which describes how to enable debugging output from dhcpd, and shows
examples of it logging a BOOTP packet exchange.

The file name it requests is specified by the server (DHCP, or
apparently as Martin explains, BOOTP). So while the firmware (dongle)
loaded by SageTV may be customized (and thus why they chose a different
file name), the MVP bootloader and MVP hardware itself are unlikely
customized.

Perhaps. Or there might have been something else wrong with the setup.

I'd recommend first trying a different DHCP server (like Dnsmasq) to
rule out that it isn't just a DHCP setup problem.

If you're still convinced that SageTV is doing something different, then
give Wireshark a spin and post your questions here to get guidance.

> Would the knowledge gained be of any value to the mvpmc community?

If it is really a SageTV specific issue, and you're the first (that we
know of) to try using a SageTV branded MVP in the history of mvpmc, then
it probably isn't going to benefit a wide audience. :-) But regardless,
we'll still do what we can to help you get it working.

Isn't SageTV Windows software? Couldn't you run it on a separate Windows
box? Or from a VM running Windows?

Re: MVP alternatives

2009-12-08T16:57:12Z

I hate going on about this, but the NMT (Popcorn Hour) is still
viable. The GB-PVR client does everything that one would need for an
mvpmc replacement and I've posted this YouTube videos before
http://www.youtube.com/watch?v=EtqHLgY8vWw. Right now I'm working
with someone on a VDR front-end now and just today someone else on the
NMT forums posted their video of what is possible with DirectFB (Jon
had the same basics over a year ago).
http://www.youtube.com/watch?v=EA0QwLROoJc

The problem isn't the MVP alternative, the problem is the lack of
desire to build this client. Given the power of the ION this is
understandable, but with the EGreat M34a NMT's at $140 it's still
relatively expensive.

No dhcp server, but they do have proprietary bootp so this still
points to dhcp problems.

Good news. At least you know there is a working combination.

I wonder...how does a rev. D MVP find its boot server in a "factory" setup? We know Hauppauge certainly doesn't have their users setup a custom configured DHCP server. And I didn't think the Hauppauge software includes a DHCP server (though it might). It seems likely that they have some made up protocol similar to the "relay service" used by the rev. H hardware.

So what would SageTV's backend have given it (since it wasn't an IP address or a dongle file)?

I doubt the MVP bootloader is dependent on a license key from the Sage software.

Do all rev D. MediaMVP's look for mvp.bin? I have not seen that in any of the documentation on the web. Therefore, I have been assuming that SageTV might have customized the firmware in this unit.

BTW, in an earlier test (about a week ago), I borrowed a WIndows laptop, installed the latest MediaMVP software from the Hauppauge website and hooked this rev D unit to the computer with a crossover cable. It would not boot. That seems to be further evidence that this unit has customized firmware.

In later (rev H) units, I do not think the SageTV-sold device have customized firmware. (Caveat - these are uneducated guesses.)

Is there a way to get this MediaMVP to work with mvpmc (given that I have done all the usual required steps)?

I think if you want to find a permanent solution that avoids running the SageTV software you'll need to break out a packet sniffer (Wireshark) running on the machine with SageTV and see what packets are being exchanged.

That is beyond my skill level. I might be interested in learning, however. Is anyone interested in partnering with me to work through this? Would the knowledge gained be of any value to the mvpmc community?

So what's the problem with using SageTV to help bootstrap the MVP?

I can't have SageTV and MythTV running on the same server at the same time. I want to run MythTV.

Did you mention that it ends up with the wrong address for the TFTP server?

No.

I wonder...how does a rev. D MVP find its boot server in a "factory"
setup? We know Hauppauge certainly doesn't have their users setup a
custom configured DHCP server. And I didn't think the Hauppauge software
includes a DHCP server (though it might). It seems likely that they have
some made up protocol similar to the "relay service" used by the rev. H
hardware.

running on the machine with SageTV and see what packets are being exchanged.

If you've succeeded in getting mvpmc to boot, there should be a way to
work around that. And if you can get a startup script to load via TFTP,
you can forcibly set any other IP addresses you need.

I haven't heard much about the MVP-HD in a while. I don't know what's
holding it up.

In the mean time, Boxee is throwing itself in the ring with a new
hardware box that might be interesting. Details are a bit scant at
this time:

http://www.engadget.com/2009/12/07/boxee-box-coming-q2-2010-d-link-revealed-as-hardware-partner/

It's worth keeping an eye on this one.

Maybe this explains it?

This email contains your software license key(s) for your [MediaMVP] purchase.

To register your Media Extender license key with SageTV go to the Start Menu->Programs->SageTV->Register SageTV Media Extender License. More information is available in the SageTV Manual, Appendix M.

Re: "factory reset" of the MediaMVP?

2009-12-07T21:49:12Z

Hopefully this will be of interest to others. I did a bit more troubleshooting.

First test:
I reinstalled SageTV and stopped MythTV backend. I left my Netgear router as the only DHCP server.

Then I plugged in the "non working" rev D MediaMVP.

It went through the usual steps (checking network, contacting dhcp, contacting mediamvp server), but then, to my surprise, it indicated that it was loading the application.

I expected to see SageTV start up. I was even more surprised when mvpmc started. My tftp server was still running but I didn't expect it to serve a dongle to an IP address in the range given by my Netgear router.

Somehow SageTV's backend gave this device something it needed that my other setup wasn't giving it. It loaded the dongle from my existing tftp server with no changes to any config and it got an IP address from my Netgear router.

So what would SageTV's backend have given it (since it wasn't an IP address or a dongle file)?

Next test:
turned off SageTV & DHCP on Netgear router (and verified it was not serving IP addresses to DHCP clients)
configured my dhcp server carefully by using all the notes in this thread.
plugged MediaMVP rev D back in and it will not boot.
Apparently it still needs something else.

Apparently, the lesson from all this is that a MediaMVP from SageTV is a bit different. Anyone disagree?

And apparently when I had this device booting previously, a SageTV server must have been running somewhere on my network. I'm guessing it only got killed by a reboot, and that must have happened at about the same time I made my edits to /etc/udhcpc.config (and which I mistakenly thought were possibly responsible for this whole issue).

Is there a way to get this MediaMVP to work with mvpmc (given that I have done all the usual required steps)?

It appears to be cycling between discover/offer, and never completing the DHCP transaction.

A normal DHCP transaction involves the exchange of 4 packets:
1. Client sends a discover broadcast.
2. Any listening DHCP servers send back an offer packet.
3. The client picks an offer it likes, and responds to a specific DHCP server.
4. That DHCP server sends back an acknowledgment, which contains basically the same info as in the offer.

Thanks for the explanation.

(Check the list archives for log transcripts of a full successful exchange. A successful mvpmc boot will have two sets, as it also requests an IP via DHCP as part of its startup process.)

I see an example of a good dhcp transaction with my Rev H MediaMVP (on the same dhcp server).

The latter two packets don't appear to be showing up in your log. That seems to suggests that the MVP's bootloader firmware either doesn't like the offer, or it is accepting another DHCP server's offer, failing to find the dongle where expected, and restarting the boot sequence.

You did turn off DHCP in your Netgear router, right?

Yes, but the Netgear router is still on my network (has to be, of course). I wonder if it still functions as a dhcp server even after the setting is turned off in the admin tool? (Next I'll try a reboot after changing that router setting.)

Correct, mvpmc does not contain the software needed to write to flash.
The version H MVP's do write to flash on their own (prior to mvpmc
loading) with info from the mvprelay/mvpboot process.

I've been patiently waiting for the MediaMVP HD unit that was touted last
March (2009) at CeBIT in the hopes that it was as 'hackable' as their
current offering is. However, I've not heard any news whatsoever on it
since then. At this point I'm leaning toward an ION based system
myself.

An MVPMC-like interface on it would be great!

I'm no expert in these things but I have 'VDPAU' selected as the 'render

'GLSL' or 'ARB').

We got a nice Sony Bravia 46" KDL46XBR6 this last summer, and while SD
is
ok, I'm looking ahead, and have the same issues. I'm going to try out
an Intel DG45GC w/E3200 (Dual Core Celeron) in a Morex 3388 case. (The
DG45FC supports HDMI on the MoBo, which is a great draw in my case).
Still
haven't decided whether to run XBMC or MythFrontend on it yet. The
simplistic functionallity of the MVPMC is just so hard to beat. I've
used
a Western Digital Media Player (w/HDMI) in our Pilot, and I'll tell you,
once you get used to being able to skip around either by index amounts
or just 30 seconds, other types don't work as nicely.

I'm thinking it may be time to start work on completing the host mode of
the
mvpmc so that it can use X, and then being able to use MVPMC in host
mode
on these ION/HTPC boards.

That's what I thought...that mvpmc will make use of data obtained by the
bootloader's DHCP client.

But files in the mvpmc image don't impact what is stored in Flash, right?

Yeah, it's a testament to Jon's (I think it's his work) simple, yet
functional MythTV client in mvpmc that it still today has better
usability than most alternatives.

I see. Makes you wonder 1. if the company really wanted to do open
source development, why did they settle for closed hardware, and 2. what
exactly do they expect third party developers to contribute, if you
can't even modify the GUI?

Seems like a disingenuous way to market the device, as others in that
thread pointed out.

Someone in that thread wrote:

XBMC is the best media frontend on any system at any price, and it's
free and open source. If one of these streamer manufacturers would
just use that, nobody would buy anything else. I guess porting
something like that is just too much effort for these small time
manufacturers.

I wonder the same thing. I can't imagine that porting would be any more
effort than building a whole media player UI from scratch. I can only
speculate that these media player appliances rely so heavily on hardware
video acceleration, that their weak CPUs wouldn't be able to render the
XBMC UI adequately. Or that there isn't enough Flash storage to contain it.

Sorry, but the above pretty much kills my enthusiasm for it. You do,
however, have my appreciation for playing lab rat and trying it out.

You should be able to find a non-hacking buyer that will value the
device for its stock functionality.

Good to know. I'll take a look.

Ugh. Next to DRM, Flash must be the single biggest obstacle slowing down
the widespread adoption of streaming video directly to set-top-boxes. If
a standard video codec was used, we probably would have seen this
functionality in cheap set-top-boxes a year or more ago. Instead we're
just now starting to see Flash playback happening in embedded devices.

Thanks Adobe. And thanks web developers who were too timid to try the
alternatives.

The chipset (Realtek) which controls the video drivers is not open source. The only thing open source about it is Linux.

I have a mvix to sell if you are interested...

I am not sure about the XBMC support for VDPAU.

If you look, you'll find quite a few of them.

The general consensus is that they make a great frontend as long as
that's as far as you want to go with them. If you want to do
something that requires the CPU and can't take advantage of hardware
acceleration (e.g. full screen flash video playback) it's a bit
underpowered. Then again, if your comparison point is the MVP, it's
practically a supercomputer.

I don't follow. You mean they don't make it easy?

They promoted that they were running Linux, made the source available,
and encouraged third party development. So shouldn't it have been
possible to port a MythTV client to it? (Not trivial, but should be
possible, unless there is no space for additional code, or they kept
important bits proprietary.)

I wonder if XBMV has VDPAU drivers?
