transcode not working

[zaprat]

In video library when I select (in PVRX2)

I get this behaviour

1. select a file
2. select transcode
3. select profile for one of presets
4. select start; which changes to stop
5. It shows a pop up transcoding in progress for about 1 sec and then returns to selected file in video library menu.
6. No file is generated.

Whats happening? Should it transcode immediately or does it happen later?

Is there a log? where can I see the command line it using to undertake the transcode?

Does it handle spaces in filenames?

If it worked, will it delete the original file or not and is a selected item

It probably means that doesnt like something about your source files. If you look in your pvrx2.exe.log you'll see the ffmpeg command line that was run. If you try manually running this from command prompt, then you'll be able see any ffmpeg error messages.

Thanks sub, I looked in the log and found the problem.

Here is the log entry

2008-08-24 13:52:55.718 VERBOSE [1] C:\Program Files\Devnz\GBPVR\Third Party\FFmpeg\ffmpeg.exe -y -i "F:\Media_1\yyyy.ts" -f avi -ab 224 -ac 2 -acodec mp3 -deinterlace -vcodec xvid -qscale 5 -vtag XVID "F:\Media_1\yyyy.avi"

When I ran this at cmd prompt it failed and for the reason the C:\Program Files\Devnz\GBPVR\Third Party\FFmpeg\ffmpeg.exe was not enclosed in quotes

It should be

"C:\Program Files\Devnz\GBPVR\Third Party\FFmpeg\ffmpeg.exe" -y -i "F:\Media_1\yyyy.ts" -f avi -ab 224 -ac 2 -acodec mp3 -deinterlace -vcodec xvid -qscale 5 -vtag XVID "F:\Media_1\yyyy.avi"

How do I get gb to insert the quotes?

Doh,

Tried it with the quotes and still did not work. It is not the executable as per previous email but in fact a problem with the command itself and compatibility with later build of FFMPEG that I am using.

I tried using a custom profiles which I have optimised for x264 and it works. I will look into why the GB presets dont work with this ffmpeg version and get back to you.

I tested here: The transcoding works fine, although the quotes are not there in the logfile.

Yeah, its not the quotes. Thats just a problem with the log message. GB-PVR doesnt need quotes when it calls the API, but I forgot to app them when producing log messages that the user might try to copy and run.

As you've already discovered, its something funny about the build of ffmpeg you're using combined with the command line that GB-PVR uses.

I see two problems with newer ffmpegs

-acodec mp3 should be -acodec libmp3lame
-ab 224 should be -ab 224k or -ab 224000
