I have a wmv file which I believe has some distortion/break points in the streams at approx 4 points. Because of this if I use ffmpeg or any other method to extract the wma audio I get 4 different delays across the audio stream to match the video stream. Is there a way I can extract the audio just as it is played back with ffdshow (I think ffdshow resyncs the audio to the video through the distortion points.) basically is it possible to losslessly pipe the audio as it is played back in some realtime audio decoder to output a uncompressed wav file result, even if I do end up waiting for an hour to have the whole stream extracted? If there is some faster way that will not add multiple delay points then please share it. I've been pulling my hair out trying to get the audio to sync to my encode of the wmv file to the wma extracted from the wmv file.
