If it happens once or mixed with other defects, it's (>90%) a tiny corruption on video file. If it happens too often and in the same way (you see 1-2 pictures and goes grey, 1-2 pictures and again grey repeteadly) then the video was codified with a feature vlc can't decode. Upgrade vlc and it's dependence libraries or use other viewer (ffplay from ffmepg) that uses other library (for H264 you have OpenH264, ffmpeg, x264, etc.. and not all of them supports all H264 subformats/modes). If you transcode it with ffmpeg check first ffmpeg/ffplay can play it nicely. --- --- Eduardo Morras
