Description

Summary of the bug: nut container doesnt' seem to "like" qtrle streams

How to reproduce:

Possibly related, if I encode it to ".avi" (which happily accepts the stream) then read it back into ffmpeg, it thinks it's "rawvideo"

$  ./ffmpeg_g -f lavfi -i testsrc=duration=10:size=1280x720:rate=30 -c:v qtrle -y yo.qtrle.avi
...
$ ./ffmpeg -i yo.qtrle.avi

Replying to rogerdpack:

The user is responsible what FFmpeg puts in a general purpose container like avi, you can use -vcodec qtrle to read it back.

current work around: use avi, though I'd prefer to use nut :)
You do have to specify it, as noted (though for other types you don't? weird)

./ffplay -vcodec qtrle yo.qtrle.avi
