[FFmpeg-devel] loop Video Filter Not Looping

[TalkVideo at TalkVideo.net]

The commands below all produce an output with a smaller video overlaid in the upper left. But, it will not loop. It plays
the overlay until its end, and stays on the last frame. 

The overlay must of course be shorter in time than the main video, but in an RTMP stream, I would like to bring overlays in and out, in order to play
clips during the stream. When the clip is done, It should disappear. 

The Warning I get is:
"[Parsed_movie_1 @ 0x3ccb380] EOF timestamp not reliable"

The overlay video was produced with the following command:

ffmpeg -y -ss 23 -i <some-video-file> -qmin 1 -qmax 2 -s 640x360 -t 2  overlay.flv
