Summary: xine-lib libffmpeg Direct Rendering img freeing

Initial Comment:
When ENABLE_DIRECT_RENDERING is defined in
src/libffmpeg/video_decoder.c, xine-lib will lose frame
buffers ('img's) at a rate of one for each stream that
is played.

Something in the direct rendering code is causing a
frame obtained through vo_get_frame (usually called as
this->stream->video_out->get_frame, 'this' being an
ff_video_decoder_t) not being placed back onto the free
queue.

This will eventually cause a deadlock where the
video-out thread waits indefinately for a decoded frame
whilst the decoder also waits indefinately for a blank
frame to decode to, and this continues forever since
there are no frames left.

Symptoms:
Xine will stop responding some time into a long
playlist of files that are decoded using the ffmpeg plugin.

Steps to reproduce:
Find a file that xine uses ffmpeg to read (eg. DV).
Create a long playlist looping this file for at least
15 times. Play the playlist.

Bug still appears to be present in CVS as of the 28th of 
March 2006 (the latest snapshot in Gentoo). The symptoms 
are as described previously.
