I run ffmpeg+raw2gmv+gmplay on Kindle but it show only blank screen.
Raw2gmv and gmplay work well ( I've tested they seperately).
Code:
[root@kindle bin]# ./ffmpeg -i http://archive.org/download/SevenWiseDwarfs/Seven
WiseDwarfs.mp4 -pix_fmt gray -vcodec rawvideo -f rawvideo -r 7.7 -y -s 800x600 -
| ./raw2gmv | ./gmplay15
