This is a variant of showwaves. It is implemented as a different filter
so that the user is not allowed to use meaningless options which belong
to showwaves (such as rate).

Major edits done by Stefano Sabatini, from a patch by ubitux.

Set this field to TRUE if the audio component is to operate on
little-endian data, and FALSE otherwise.

However TRUE and FALSE are not defined. Since this flag is just a boolean,
interpret all values except for 0 as little endian.

Sample-Id: 64bit_FLOAT_Little_Endian.mov

Prevents unsigned overflow and variable truncation.

Bug-Id: CID 603186

This is a leftover from the static to dynamic vlc table conversion.

Instead check for all mov code-points when demuxing avi
and print a warning if a video codec is found like this.
