FFmpeg: "[h264 @ <hexnumber>] AVC: only n bytes are consumed instead of n + 6"

Question

When I convert HD video, I get messages saying: "[h264 @] AVC: only n bytes are consumed instead of n + 6"

Is there a way to fix the problem? Or is it possible to get rid of these messages?

Probably the problem is that six sentin bytes have been added to the end of the frame. They are completely harmless, but are inserted by some sensors as markers. Until the command fixes this, you will need to fix and rebuild FFMPEG. The team semi-fixed it for cases when all other bytes are zeros, however, an error occurs quite often when special encoders (in particular, Adobe) act stupidly.
