The spec indeed says the metadata for codecid are double. But as @Fenrirthviti said, why bother ? the audio/video streams are usually decoded directly without compulsory reliance on the container and it's not as if it was required to provide these metadatas or any metadata btw ... For instance width/height/videodatarate medatatas will be read directly from the sps/pps headers in video stream. It's the pair h264/aac which is the de facto standard codecs for rtmp/flv ... Who's using h263/vp6 or mp3 ?

I have problems writing rtmpclient and parsing metada. It is just a suggestion
