Would you please get the following patch: <a href="https://github.com/01org/player-ffmpeg-yami" target="_blank">https://github.com/01org/player-ffmpeg-yami</a> Please follow the readme in the patch to apply and build the example palyer. 1. setup env for ffmpeg build: "source build-ffmpeg.env" 2. build ffmpeg (with yami patches): "make ffmpeg" by default, ffmpeg is installed to /opt/ffmpeg 3. build the example player: "make player" I have tried "player -I Geldkoffer.mp4 -m 1", the file can be played well.
