'error while decoding' where?!

[asarian]

Tried to verify a file, with ffmpeg, and got this back:

[h264 @ 0000000002ed5080] left block unavailable for requested intra4x4 mode -1
[h264 @ 0000000002ed5080] error while decoding MB 0 4, bytestream 40329


Where is that error supposed to be?! (What frame, I mean)

Try VirtualDub - Video - Scan video stream for errors... Install plugin for read mp4 files if needed.
