I tested the metadata astats filters with the latest drawgraph patch. I find this adds a lot of ability to visualize audio information. Here's a few comments from testing. I suggest adding a reset_count/reset option similar to what is in cropdetect, so that audio information could either be graphed frame-by-frame or summarized as it accumulates. With my samples the filter defaulted to an audio frame size of 1024. I realize that I could set asetnsamples before astats to change that, but could the audio frame size be set within the astats filter. Thanks so much, Dave Rice _______________________________________________ ffmpeg-devel mailing list ffmpeg-devel@ffmpeg.org http://ffmpeg.org/mailman/listinfo/ffmpeg-devel
