is there any 'easy' way to locate the specific syntax unit(like an intra dct coefficient in 8x8 blocks) in a mpeg4 visual stream?

or just say , the only way to do it is analysing the stream with all the detail?

No easy way at all. You have to decode the stream to get those. EDIT Use ffmpeg to get those. A single fprintf in the right place should give it to you.

  • Welcome. Accepting the answer would be a nice thank you :). Use ffmpeg to get it. A few fwrites in the right place will give you all syntactic elements. To cross verify you can use elecard analyzer. Its a windows tool but it is very good. The demo version allows you to go upto 200 frames. There is also something called codecvisa for linux but only 2 frames for demo mode. – av501 Aug 31 '12 at 20:53
