Emulation mode testing Round III

[pz1]

I've uploaded a new dongle to address the 1 track issue. I'm pretty sure it was the file size problem. As for rebooting the power off really does a good job of cleaning memory, you should rarely have to do more than that unless the video thread really became corrupt.

ML2 is happy again.

I've been testing the latest dongles (up to 04-26) with Live TV and can't get it to work properly.

Pre delay is set to 600 (default). For testing I'm using a DVB Nova-t 500 tuner and Cyberlink mux.

When I select Live TV, I get the OSD after about 5 seconds then video/audio start ok. If I press channel Up or Down, after about 4-5 seconds the video stops then the screen flashes with the main MVP menu before droping back to the MVPMC menu. Sometimes the MVPMC software will re-start.

If I'm in Live TV and I press a channel number, the OSD appears with the number in the corner for about 3 seconds then the flash of GBPVR menu before dropping back to the mvpmc menu.

Running the standard GBPVR dongle works ok in Live TV.

I'm a bit confused because of this post

Was that related to mvpmc too?

In any if you are interested in setting up an mvpmc share and doing some debugging via telnet I'd be able to pin point the problem a bit more. Let me know if you are interested.

Edit: Here are instructions on how you would do that

Hi,

No the two problems are not related. I have a dedicated WinXP machine for GBPVR and run 3 MVPs. I use the Nova-t 500 dual DVB tuner.

There is a problem with the current GBPVR software /dongle combination which stops responding to MVP remote commands during video playback. There are many posts on this problem. This lead me to try the mvpmc dongle.

When GBPVR is set to DVR-MS format, I transcode on recording completion to mpg and it plays fine on the MVP. If I set GBPVR to use Cyberlink for recording, it loses audio sync 5-10 minutes into the recording. This is why I use DVR-MS and transcode.

For Live TV, the DVR-MS temporary recording file gets transcoded by Trans2mvp (ffmpeg) and the MVP starts playback from the resultant mpg file. At a random time after the start, the playback stops and drops back to the main menu. It can be triggered by a channel change.

Sub said in his initial response that if I want to play Live TV on the MVP, I'd need to set GBPVR to use the Cyberlink mux. That works fine for Live TV on the MVP but as I said above, it's crap for recordings because of the sync loss.

All the testing I've done with mvpmc has been done with the Cyberlink mux selected and I've compared two MVPs side by side. One using GBPVR dongle and the other with the mvpmc dongle.

The dropout when I change channel with the mvpmc dongle gives this entry in the logs:-

Is that any help?

From the time, I think that's the point it seems to drop out.

I actually don't have means of testing livetv that is transcoded with ffmeg

Finally you can't stream the next 200000 your read only emptied the prebuffer,

No new data is being read and so gbpvr stops. You can look at the mvpmc logs via telnet, but I don't think that you will find any to help you capture data at the required speed.

I think I have found a small "problem". When I start select a recording, a screen comes up with the options Play, Delete and Close. When I've watched the recording and I press the stop on my remote, the screen I mentioned is still visible and I have to press another key on my remote to make it go away.

When a recording ended, I had to press a key to return to the plug-in screen. Likewise, when a scheduled recording began I had to press a key to get out of the stopped video. And once changing channels with the number keys I had to press a remote key to finish the channel change.

I believe I have trapped the condition that was causing this problem and uploaded yet another alpha. Let's see how 0427 works.

Hi Martin,

The screen is gone. Thanks!

[Bobins]

The reference to DVR-MS & transcode is how I normally run my setup but for testing with mvpmc, I've specifically set GBPVR to record straight to mpg using the Cyberlink mux (so no transcode is involved). Sorry if I'm confusing things.

I'm in a PAL region (UK). My network is hardwired Gigabit (obviously the MVPs are not) and the server is an AthlonXP 64 3800. Cpu stats show 5% when recording or playback so it's not breaking into a sweat.

This only happens when you change channel in mvpmc.

I've included a complete log where I start watching live tv, wait a minute or so then change channel.

Here's a log with me changing channel with the standard GBPVR dongle (time of change 10.04.34)

You'll notice different entries in the log.

Sorry, I'm a bit lost on this without the mvpmc side logs. If you you scroll back on this thread I gave you a link to the process to do this.
