I have tested in Firefox Now my question is, If i use <audio/> tag with src as a video file, then 1) Do firefox stream whole video file and play only audio part OR 2) Do firefox stream only audio part of the file and play it. I want to know, is there any bandwidth advantage with <audio/> tag over <video> tag ? If I am unable to explain, do let me know, I will try again... -------------- next part -------------- An HTML attachment was scrubbed...

If the file contains multiple audio tracks and/or other information that will be streamed and ignored by Firefox too. Chris. -- http://bluishcoder.co.nz

So if you want to just play the audio and not send any video, you need to prepare a new file containing only the audio track, eg: $ oggz rip -c vorbis -o Big_Buck_Bunny_Trailer_audio.ogg Big_Buck_Bunny_Trailer_400p.ogg and then use the newly created file in the audio tag: <audio src="Big_Buck_Bunny_Trailer_audio.ogg" controls="controls"> your browser does not support the audio tag </audio> Conrad.
Thanks,
It will be very good if HTML5 API specify this. I mean, Say, If we use
<audio> tag , then It must stream only audio part of the file irrespective
of the fact that the src field contains a video file.
PS: sorry for top post
