You didn't say which filter you want to use but is there any indication that the pcm decoder has processing time compared to the filter you need?

What advantage would this have over "decoding" your pcm audio with the appropriate decoder? Carl Eugen ___ Libav-user mailing list Libav-user@ffmpeg.org http://ffmpeg.org/mailman/listinfo/libav-user
