That's not a good way to detect scene changes, think for example of a stream with uncompressed video frames, also I-frames aren't necessarily used in correspondence of a scene change. > but I would like to detect when at the same time of an I-frame > there's silence in the audio. > > Is it something feasible with libav? Libavfilter is the framework meant to solve with elegance that kind of problems. Also you need some algorithm to determine the noise threshold in the audio frames (though I'm not sure libavfilter as it is in the GSOC repository may be used for audio frames also).
