Hi, guys.
I am unable to make VLC output logs to a file. I have tried all options outlined in VLC help:

vlc -vvv --file-logging --logfile=foo.log --logmode=text creation.mpg

vlc -vvv --file-logging --logfile=foo.log --logmode=html creation.mpg

vlc -vvv --file-logging --rrd-file=foo.log creation.mpg

Log file is never even created. The only relevant output of VLC seems to be this:

main error: option syslog does not exist

I have tested this on Linux(Ubuntu) and Mac OS X and it works fine, but on XP no such luck.

edit: VLC 0.9.8a

I can replicate this.

Perhaps this topic viewtopic.php?f=14&t=52885 helps you further?

I'm having similar difficulties, but I did find something of a workaround.

First of all, the linked post above suggests:
"vlc INPUT --file-logging --logfile file_log.txt"
but aren't the rules on Windows that you must use the "--option=value" syntax, not "--option value" ?

Anyway, I tried all variations and the only way I can get a log file is to use the following combo:

""C:\Program Files\VideoLAN\VLC\vlc" P1000098.mov --extraintf=logger --verbose=2 ..."

This causes a log file named vlc-log.txt to be written in the current directory, as well as a log screen to be displayed during the processing. I have not found a way to give it a different name (not that I care).

What is more interesting/concerning, though, is that this file (vlc-log-txt) does not contain ALL the info shown on the screen. Even with --verbose=2 (or 3), I get a lot of 'main debug: ...' lines, etc, but what I DON'T get, and what is relevant to my current troubleshooting exercise, are entries such as this:
(I copied these from the screen log)

Hi,

I am using following options

string[] initOptions = { NativeLibVlc.vlcInstallDirectory,
":no-one-instance",
":no-loop",
":no-drop-late-frames",
":disable-screensaver",
":vout=vout_directx",
"vlc INPUT --file-logging --logfile=" + NativeLibVlc.vlcInstallDirectory
+ "LogFile" + vlcHandle.ToString() + ".txt",
"--plugin-path=" + NativeLibVlc.vlcInstallDirectory
+ @"\plugins" };


but I cannot see the log file at vlc installation directory.

Ram.
