Situation critical

The BBC's desperate attempt to lead the new media revolution has been fraught with controversy, delays and huge costs. Bobbie Johnson asks how it all went wrong

Save this script somewhere, e.g. /usr/local/bin/podit, then chmod 755 /usr/local/bin/podit

Usage: podit /path/to/file

Update: Apparently ffmpeg's parameters have changed yet again [sigh]. Depending on what version of ffmpeg you are using, you may need to make the following changes:

Update 1:
-vcodec h264 is now "-vcodec libx264"
-acodec aac is now "-acodec libfaac"

Update 2:
-me is now "-me_method"
-loop is now "-flags +loop"
-slice is now "-flags +slice"
(To set both the above, use "-flags +loop+slice"
-part[xxx] is now "-partitions +parti4x4+partp8x8+partb8x8"
-brdo has gone. This is automatically set if "-subq" is 7 or higher
-chroma is now "-cmp +chroma"

Also ... nobody noticed that "aspect_ratio=xxx" was missing from the variables section (as it stood, this script would not have worked, but just produce an error "invalid aspect ratio")? Oh well, it's fixed now :)

Thanks to FakeOutdoorsman for update 1, and various sources for update 2.
