[FFmpeg-user] qtrle in an avi results in "non video" playback

[Roger Pack]

Greetings:

I noticed that this works:

$ ffmpeg -i something -vcodec qtrle -o yo.mov

however this results in a file that plays back "without video" in
ffplay/vlc/mplayer:

$ ffmpeg -i something -vcodec qtrle -o yo.mov

Does this mean that the avi mixer should "reject" qtrle, or this is a
bug? Worth reporting do you think?
Thank you.
