'vlc v4l2c:///dev/video0 --demux h264' might work "thanks" to a software bug whereby the format is not reset, but I have not tried. V4L2 H.264 is supported in VLC version 2.0.2-git: 'vlc v4l2:///dev/video0:chroma=h264'. -- Rémi Denis-Courmont Sent from my collocated server -- To unsubscribe from this list: send the line "unsubscribe linux-media" in the body of a message to [email protected] More majordomo info at http://vger.kernel.org/majordomo-info.html
