Pregunta
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?
Solución
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.
