MVP and AVIs

[sub]

Green Power Button on MVP:
Does the Green Power Button suspend the MVP as described in the MVP manual? I ask because I had an interesting experience. I think I accidently started 2 MVP servers on my primary PC, (Athlon64 3300+ 512mb 160g hd). I had the autostart set to 1 and I manually started a second (didn't relize I had the autostart set) When I was testing the MVP, It would sometimes display the contacting server messege, I think it was switching between the two servers.

Pressing the power button causes the MVP to go into its power save mode. When you press it again it'll boot up and connect to the first GB-PVR server it can find.

You should use the MVP servers with the auto-start setting. These behave slightly different to ones that were started manually. When you press the green power button with these, they restart to free any resources. Manual ones dont do.

If they'd both been auto start ones, then you wouldnt have been able to tell it was a different one you'd reconnected to (since both would show the main menu).

Using latest GB-PVR with FFDShow, I still get audio sync problem with avi files..there is about a 5 second delay...should I be using the FFDShow audio codec? FFDShow video and audio icons appears on my task panel when playing back videos..If so, what are some FFDShow audio settings I should be working on..GB-PVR is checked for FFDShow Transcoding and Post-Processing.

Thanx..

To be honest I dont know.

It seems that everyone has different experience with Avis, and due to the forest of codecs out there.
If you look back in the thread, you'll see that there's a couple more paths to explore than FFDshow.
First, make sure you have the right codecs installed, Sub posted a link to the 2.5beta version of the MVP software, you should definitely install this.
Second, in the Playback tab, max out the preplay delays for the MVP. This makes it longer for the MVP to start playing, but usually makes it a lot smoother during playback.

Good luck.

First of all I like to say thanks for all of your support here in the forum! I recently installed gbpvr and ran into all the problems mentioned here at the forum... after a week of 'configuring' every night after work I finally got everything to work (almost) properly using all of the comments in this forum and some 'fumbling' of my own.
Now after using all of your knowledge, it is my turn to share my findings:

- for use with ffdshow: I startup GBPVR MVP Server under the user that is logged on, turned on 'tray icon' in ffdshow, so I can see that it is activated.

- for a full screen image: I use ffdshow and always resize* to 480x280 (played around with this, and it differs per tv-set what the best size is, for me it is this setting, for a completely filled tv screen)
* ffdshow works the tasks consecutieve so when using subtitles put the priority below the resize task (or your subtitles will be resized also, not always pretty) and turn the lettorbox option on: don't resize

- audio and video completely out of sync: I had some .avi that were 23.976fps while I live in a 25.000fps country (Netherlands) . So probably the audio track of the .avi is not converted to 25.000 while it plays back on the TV. I resolved this by converting all my movies (those that were not already) to 25.000fps (using virtualdub and besweet (for audio))

- crash/disconnect when trying to add a subtitle: Reinstalled Vobsub... et voila... :confused:

I did a lot more stuff but most of it was just 'fumbling' that lead to nothing <sigh>, but now I at least understand (kinda) how the stuff all works together...

Now, just 1 more thing before I achieve a perfect-high-quality-avi-playing-super machine....

: When playing some .avi files the sound gradually runs out-of-sync.
Looks like the trans2mvp.exe runs into errors somewhere... Can it has anything to do with the trans2mvp.exe popping-up a dos-box on my computer with some 'weird errors' in them... (e.a. malloc, free, err_printf, prg_printf, wrn_printf, inf_printf, yield, notinitialized: yield)
I think this is causing audio-desync from my video... ??

Like this it gets rather anoying watching the particular movie.
And since the stop and resume function does not work (always resets to start of movie) I cannot do anything about it for this particular movie(s)...
I tried to convert the movie(s) to different video codecs and formats, and with different audio codecs and formats... but the de-sync stays... and it always seems to start on the same position in the movie, so it is not random and caused by computer lagging....

Can anyone tell me what the problem might be?

Good write up.

trans2mvp is that dos-box, so its not cause of the out of sync. The weird debug message malloc, free, err_printf, prg_printf, wrn_printf, inf_printf, yield etc seem to be caused by the Hauppauge Mainconcept encoder. For some reason its printing out this diagnostic information as it runs. This in itself is not a problem.

For AVI (xvid) playback, Which I can't get to work. According to this thread I looks like I should remove my divx codec and install FFDShow. Is FFDShow a full standalone codec? From what I read in the forum it looks like the best way to get AVI playback to work through GBPVR. Currently I get a black screen when trying to playack a AVI file. It almost worked once or twice, It showed a few seconds, then displayed the resume/restart screen and went black. I have since disabled the resume feature, but I still get the black screen.

Email your logs to me at support@devnz.com and I'll take a look at the AVI problem.

Sub,
I have been able to get my AVI playback to work on my MVP. I still have issues but I wanted to thank you for offering to look at my logs. When I checked the transtomvp log I found it was trying to write the temp file to my Z: drive (Recording drive). In my case Z: is a network drive that is not always avilable.

Now my issues are the same others have described in this thread. My AVI is "letterboxed" or displaced on the screen, and my audio is out of sync. I have added FFDShow but it didn't seem to help, even when I resize the video to 640x480. I think I need to re-read this thread and look for other things to try. But I'm open to suggestions.

Anyone:
Can someone tell me what the proper settings for FFDShow would be to get full screen playback, and how to apply them.

For instance: Open FFDShow, change "a", change "b", change "C", Click apply, Click OK, Restart GPBVR, Reboot, Stand on your head and pray to the PVR GOD. Log back into your PC, Restart MVP . . . . .

Make sure you are using the same user account for FFDShow & GBPVR

Thank's I was re-reading another post that made the same suggestion. I'll try it again when I'm home.

: When playing some .avi files the sound gradually runs out-of-sync.

Well, I resolved this problem... It seemed that the 'ac3filter_0_70b' was causing this problem. When a movie had a AC3 (Dolby Digital) audio track a movie played fine. Ffdshow used the AC3Filter, but when playing movies another type of audio track in them the movie gradually ran out of sync (where it looks fine at the start). Even when not a AC3 audio track, ffdshow used the AC3 codec and this caused the problem. I deinstalled codec and now everything seems to run fine! Even the AC3 movies still run!
I was so focussed on finding the problem in avi2mvp that I missed this one...

Just for the record: I use (only) a P4 1,70ghz machine and a MVP-Player (so no special PVR hardware) and had all the same problems that everyone else in this forum is experiencing... But now I have it all perfectly running... (can even run other task on my machine while playing a movie) So I think this shows that the software Sub is supplying works fine even with a 'slower' machine... Takes some configuring though ;-)
Only thing I cannot resolve is the resume issue...

My advice to everyone: Take a small segment of a movie, convert it to different video codecs, audio codecs, size etc. (using virtualdub). And go and do 'trial and error'. This way you can play arround with the ffdshow settings and see what the results are. And I would deinstall all the codecs from your machine and just install the ones really needed (If it plays on your computer, it plays on your tv)... (I have XviD-1.0.3, DivX511 and no special audio codecs)

Thanks for this great and leading piece of software Sub! I can't wait for the next releases...!

By the way Sub, do you have (had) contact with Hauppauge about this software? If they see this they must be intrested right? If you compare this with the 'stuff' they come up with... This could be their difference between an 'Ok' MVP and a 'great' MVP!
