Is it possible to to concatenate parts of two or more video blobs encoded in webm format using just client side javascript?
回答1:
What you are looking for is the media source extension as defined here: http://www.w3.org/TR/media-source/
Both Firefox (partially), Opera Chrome already support this. IE11 only on Windows 8+.
Also, take a look at DASH (https://en.wikipedia.org/wiki/Dynamic_Adaptive_Streaming_over_HTTP) and HLS (https://en.wikipedia.org/wiki/HTTP_Live_Streaming)
