Does dvbsnoop analyze MPEG video/audio stream content?
dvbsnoop decodes meta information about dvb and mpeg streams, but does not analyze video or audio stream content in detail, which is described outside ISO/IEC 13818-1 / ITU H.222.0. There are other good tools available to analyze e.g. mpeg video I-frame rates, compression rates, mpeg vectors, etc.. You may use dvbsnoop in combination with these tools. Latest versions of dvbsnoop are doing a rough ISO/IEC 13818-2 analyze of a mpeg stream.
