Hi,

In some encodes I’m having the following error while encoding with x264 and using –-demuxer lavf:

error while decoding MB xx y
concealing zz DC, zz AC, zz MV errors

But after looking at the resulting frames apparently there aren’t any issues.

Could anybody please tell me what this error means and if I have to worry about it? Thanks

Greetings

Sorry for the pump up, but anybody has ever encountered this problem?

Could at least anyone please tell me what this error means?

Greetings

Sounds like there is some error in your input stream. The error might be too subtle to be apparent in the final output though...

Yep. Especially when the decoder is concealing it, which works pretty well for MPEG-1/2, at least.

Thanks to both.

So concealing means that it has been able to more or less hide these errors? As I said I don't see any artifact nor corruption, bau maybe one pixel here and other there are wrong.

Correct.
