I have a html5 video tag with src attribute pointing to some website with mp4 file. Is it possible to get contents of this video when it has loaded as base64 string?
UPD: I need binary video data inside browser.
Thanx.

If "some website" is not on the same domain as your webpage then you probably will not be able to get frames from the video exported to base64 urls -- that's because of security restrictions. If the security restrictions don't apply then check this previous post showing [how to capture frames from a video element](http://stackoverflow.com/questions/33917800/screenshot-from-video-at-different-time/33925844#33925844). – markE Jan 29 '16 at 18:36

@markE I'm not sure if OP wants each frame as dataURI or the whole media. For the later, xhr+filereader would be a better option (almost same crossorigin restrictions though) – Kaiido Jan 30 '16 at 05:39

@Kaiido. You mean re-encode the whole video? Awfully inefficient to use canvas to do that. – markE Jan 30 '16 at 06:11

@markE yep, but except the tag, there is no mention of canvas in OP, nor in my comment ;-) – Kaiido Jan 30 '16 at 07:38

@Kaiido. But isn't the 'canvas' tag there to do the re-encoding...else why have the canvas tag at all? Anyway, I don't understand what the OP is asking ... what are they trying to do? Do they really want to re-encode a whole video as a set of base64 strings --- weird? – markE Jan 30 '16 at 07:47

1@markE I'm not sure either :/ IMM, canvas is one way OP does know for encoding still images, hence the tag. But clearly this is not the best way for a full video. Looking forward for more info from OP. – Kaiido Jan 30 '16 at 07:49

@Kaiido, -- updated q. to give more details – Stepan Yakovenko Jan 31 '16 at 07:49

@StepanYakovenko "binary" or "base64 string" ? Also you do realize you will play with heavily large objects ? – Kaiido Jan 31 '16 at 08:03
