Cannot restore segment prot after reloc: Permiss

Occured when attempting to load the libphp5.so module into Apache using RedHat linux.

Fixed by running:

system-config-securitylevel

and setting SELinux to Permissive

Creating flash video (flv) files with ffmpeg

First, install Lame., to access the mp3 codec.
Second, install ffmpeg. Ensuring that you run the configure script with the --enable-libmp3lame option.
(I used ./configure --disable-vhook --enable-x11grab --enable-gpl --disable-bzlib --enable-libx264 --enable-libmp3lame).

Thirdly, use ffmpeg thus:
ffmpeg -i myinputfile.mpeg -ar 22050 -ab 56000 -b 200000 -acodec libmp3lame -ac 1 myoutputfile.flv

Flash files won't work in any old directory?

Flash player 9 (and presumably all subsequent releases) have security features that limit where data and files can be accessed from.
Check the following directory (under windows):

c:\Documents and Settings\\Application Data\Macromedia\Flash Player\#Security\FlashPlayerTrust

Within will be some .cfg files, each specifying permitted directories for playing Flash (SWF) files.
Feel free to add your own,
i.e. file: mydir.cfg
contents: C:\temp

Will allow you to play swf files in your c:\temp directory
