Hi all,

I can't activate post processing with VLC 1.1.11 on Lion 10.7.1. I get the following on the console:

27/09/11 11:13:15,375 [0x0-0xbb8bb8].org.videolan.vlc: [0x1021ee108] postproc filter error: Error while creating post processing mode.
27/09/11 11:13:15,376 [0x0-0xbb8bb8].org.videolan.vlc: [0x102171308] main video output error: Failed to create video filter2 'postproc'
27/09/11 11:13:15,376 [0x0-0xbb8bb8].org.videolan.vlc: [0x102171308] main video output error: Failed while trying to append 'postproc' to filter chain
27/09/11 11:13:15,376 [0x0-0xbb8bb8].org.videolan.vlc: [0x102171308] main video output error: Video filter chain creation failed

Is it a known issue ?

Not at all. Tried to reinstall VLC and deleted its preferences (a folder called "org.videolan.vlc" in ~/Library/Preferences)?

Unfortunately, in OS X Lion 10.7.2 and VLC 10.1.12 post processing via postproc is still broken and disables the whole filter chain.
I guess the dynamic library of postproc itselfs got some errors in 10.1.10 and is still not fixed yet up to the current version of VLC.

But I have success with replacing the postproc lib with the older last functioning one from version 10.1.9.
Simply download 10.1.9 again and open the package contents of that one and your current VLC.app. In path

VLC.app/Contents/MacOS/plugins/

There, you will find a file with name libpostproc_plugin.dylib.
Copy this one from version 10.1.9 over the one of your current version and voila: postproc and the filter chain are working again.
