Transcoding with FFMPEG

[mazachan]

Hi all, I've been having a problem with transcoding using FFMPEG. Even though I set the bitrate to -b 1400, I open the transcoded file up with GSpot and it says the bitrate is only 2kbps. I do not have GBPVR.exe running while it is transcoding. I looked in the log files to see if there were any debug information and there was none to be found in ANY of the log files. The conversions take place between midnight and 6am, and there are no timestamps whatsoever. The only things I see in the log files is when I start GBPVR up in the morning.

If anyone can help, it would be greatly appreciated. Thanks.

The original file is gone? Are you sure you didn't make a typo when you changed the bitrate. What's the commandline for ffmpeg you are using?

No, the log files are there. But there is NOTHING in the files from 12AM-6AM (in any of them). The only thing that is in the log files is when it starts recording a show at 6am. There is nothing in the logs that says it's kicking off a process to start conversion.

These are the two settings for XVID and DIVX

<Conversion name="XviD" exe="ffmpeg.exe" cmd="-y -i {SOURCE_FILE} -b 1400 -f avi -ab 224 -ac 2 -acodec mp3 -vcodec mpeg4 -s 640x480 -vtag XVID {DEST_FILE}" targetExtension=".avi" />
<Conversion name="DivX" exe="ffmpeg.exe" cmd="-y -i {SOURCE_FILE} -b 1400 -f avi -ab 224 -ac 2 -acodec mp3 -vcodec mpeg4 -s 640x480 -vtag DIVX {DEST_FILE}" targetExtension=".avi" />

As far as I can tell, 1400 is supposed to be 1400kbps, correct? Or at least that's what it says in the ffmpeg docs. But I find it bizarre that it kicks off the conversion and nothing is logged, even though the logging is set to debug mode.

I just did a test, with a short recording. I set the conversion to ASAP.
I got the following in gbpvrrecordingservice.log:

Code:

So for me it works and it gets logged aswell.
