Not in Dolphin ;-)

kdemultimedia has two different thumbnailers (ffmpegthumbs and mplayerthumbs). If you know which one is being used on your system (unfortunately, I don't know a good way to find out right now), this report can be re-assigned properly.

rosa uses gstreamer for kde thumbnailing
i assume gstreamer uses ffmpeg

it seems it's a general pb :

- Romp (rosa multimedia app) uses mplayer : same pb , views in landscape instead of portrait
- vlc same pb, views in landscape instead of portrait
- totem uses gstreamer : same pb , views in landscape instead of portrait
- picasaweb uses flashplayer : no pb

perhaps there is a tag in mp4 file about portrait/landscape mode as in photo file .

Yes, but the decoder needs to read and handle it. If stand-alone mplayer and/or ffmpeg work correctly, but KDE applications do not, please reopen. In this case the decoders handle rotation, but need assistance from the applications.
