File transcode has completed unsuccessfully

Hi guys,

I am having a problem with transcoding with GB-PVR after I recently upgraded to gb-pvr 1.0.16.

I just noticed this as none of my shows were being transcoded to iPod format any longer and so I started to look through the logs (Don't make fun of the show names, it's for the kids )

Here's what the log shows, I just don't understand why it is not working. I tried running ffmpeg from the command line using the same parameters as shown in the log file and it converted ok.

Can anyone please offer some advice?
Thanks,
Gary

All I can suggesst is cut&pasting that ffmpeg command into a command prompt and seeing if it generates any useful error text. Other than that I dont really have any suggestions.

Hi, actually I did that and it worked great.

I had to run it from the ffmpeg directory because when I cut and pasted the line exactly as shown to the command prompt it complained because I did not have the filename/filepath in quotes, it didn't like the spaces in "Program Files".

Once I went into the Third Party/ffmpeg directly and ran ffmpeg directly from that directory with all of the command parameters shown in the log it worked fine. These ffmpeg parameters are the default video for ipod settings in the config.xml file.

Sorry, I dont know then.

I had to run it from the ffmpeg directory because when I cut and pasted the line exactly as shown to the command prompt it complained because I did not have the filename/filepath in quotes, it didn't like the spaces in "Program Files".

Thats not the cause of the problem when run from the application though. The quotes are not required around the executable name in the API I used. These quotes are only required so CMD.exe can parse the command line.

-maxfr 30 that doesn't seem to be a valid option...typo?
should be -maxrate i'm guessing...
ffmpeg version may be the culprit...they change the syntax again?
at least i didn't find it in the newest ffmpeg docs..

Hi Guys,

Well for fun I tried the old version of ffmpeg I was using with the old version of GB-PVR and it seems to be transcoding properly for me now.

Incidentally, now that I have done that I remember having problems with the ffmpeg originally bundled with my old version of GB-PVR.

To get it working on my old version of GB-PVR I also had to replace the ffmpeg.exe file with another version of ffmpeg that came with 3GP_Converter 0.34 (http://www.nurs.or.jp/%7Ecalcium/3gpp/). When I did that then it also solved a problem I had trying to convert files into .mp4 files for the iPod. I totally forgot about that until just now as I'm writing this response.

Thanks for the suggestions guys, and thanks for GB-PVR! Awesome program!

Gary
