But I still have the problem of non working output. Does output is really needed for going out of staging ? Probably nobody have it working for ages. The only way to had it was to use an old mplayer output which is broken since so many time. Note that this plugin will never work again. The only way to work on output is to use ffmpeg which just recently have suport for writing non-raw video to V4L. Regards
