I get similar messages on all or nearly all mpeg2ts files. Even ones with minimal artifacts.

Are these transport streams from DVB? Then they will probably have bit errors caused by bad reception. The transport stream is not supposed to correct these, the lower layer (DVB itself) is supposed to take care of these by using forward error correction.

Nevertheless you might want to try projectx which will signal and drop packets that have bit errors. This might make it easier for ffmpeg to make something out of it. -------------- next part -------------- A non-text attachment was scrubbed...
