ZProcess: Can Transcode but MVP crashes...

[zehd]

I created the same directory structure as you are using and renamed on eof my avi to match yours...

I copied the command line GB-PVR is passing into a commdline.

As is, it errors because there is no quotes around the ZProcess full path (the space in 'Program Files' and 'Third Party' is causing trouble.

Wrapping the first file spec in quotes work. I have found it doesn't matter about the single or double slash...

Code:

"C:\Program Files\devnz\gbpvr\\Third Party\Zprocess\ZProcess.exe" -y -i "D:\Video's\Input\101_0146c.avi" -b 2400k -ac 2 -ab 128 -r 29.97 -s 352x240 -f svcd "D:\Video's\MVP000DFE0002D11.mpg"

Now, I haven't had this problem before. But I'll call sub over here to have a look at it...

That wont be the cause for this problem via GB-PVR. The ProcessStartInfo() class I use takes the executable as a separate parameter, so no quotes are needed to identify the beginning and end of the executable name.

My guess is its something to do with the apostrophe in the recordings directory name.

Zehd and Sub, I loaded the lastest version of Zprocess, renamed the video's directory to videos, and tried a couple transcodes from the MVP. The first is at 2:50:42 and the second at 2:52:45. Both caused the MVP to reboot. Here's the logs.

According to the logs, GB-PVR tries to run ZProcess with the following command line, expecting MVP000DFE0002D11.mpg to be created.

Soon after it attempts to play this file, but its not found.

At 2:45, ZProcess restarted the recording service...

Code:

Did you ask it to? It shouldn't have.

According to the logs, It was never started, at all. GB-PVR never called it...

(first thing ZProcess does when it's started is add an entry to the log stating it started...)

@sub, You mentioned that your file launch mechansim doesn't require quotes. I get that, seen that before even...

It seems though, that ZProcess is not launched. I would not doubt it's similar to lanching the command line as it is from a dos box (where it stops because of the long file names)

@murf64, I suppose we could try the original launching way...

1. Only use the ffmpeg folder,
   
2. rename the real ffmpeg.exe to fmpeg,
   
3. rename zprocess.exe to ffmpeg.exe,
   
4. open ZProcess, 'find' the fmpeg.exe (one f)
   
5. ask it to remove references to ZProcess in config.xml,
   

Then try again, with GB-PVR being fooled again into thinking it's dealing with ffmpeg.exe natively...

This is an example of the log as it should look:

At the very least there should be a started entry...

OK, my power was out here in Michigan for a couple days, but I'm up and running again. I tried a couple transcodes, and made some notes on the zprocess log. I hope it helps.

I see what you're doing is trying many different ways. Unfortunately we shouldn't. I know that your goal is MVP and MEncoder.

But I want to be sure that all your AVIs transcode manually, to completion with FFmpeg, then try the same group of AVIs with MEncoder. The logs have to show everything cool...

Then once we know the profile works, then we don't touch it, while we try and figure out why GB-PVR isn't Calling ZProcess...

I might want to Remote control in, if you're cool with that...

Zehd, You lost me here. Everything has been transcoding fine with ffmpeg and mencoder on the pc, even through GBPVR (on the pc) or via a batch file (on the pc). The only time I have any trouble is through the MVP. There's some disconnect between zprocess and mvp. Look at gbpvr.exe-1.log at 1/22/2007 10:17:32 AM.348, I tried to use the "transcode" feature on the MVP, and it sent it into some loop.
