I'm using Bento4 to create mpeg-dash that encrypted with Widevine DRM protection.\r\n2. I'm using ExoPlayer Demo to play the mpeg-dash content (that created by Bento4).\r\n3. I've noticed that that whole content is encrypted (Starting from the first segments).\r\n4. I've notices that some of the samples that ExoPlayer provides are DRM protected, BUT:\r\nthe first couple of seconds (~8 seconds) of the media ARE NOT encrypted.\r\nThis used for ExoPlayer starting to play the media and requesting the decryption keys from the license provider in parallel.\r\n\r\nI need to create mpeg-dash that is DRM protected as ExoPlayer did, i.e. the first couple of seconds will be unencrypted (to let ExoPlayer start to play the media while we're waiting for the keys response from the license provider).\r\nCan I achieve that with Bento4 tool?\r\n\r\nThanks in advance for any advice.\r\n\r\n"},"comment":{"url":"https://api.github.com/repos/axiomatic-systems/Bento4/issues/comments/171241874","html_url":"https://github.com/axiomatic-systems/Bento4/issues/54#issuecomment-171241874","issue_url":"https://api.github.com/repos/axiomatic-systems/Bento4/issues/54","id":171241874,"user":{"login":"almoghzn","id":16574356,"avatar_url":"https://avatars.githubusercontent.com/u/16574356?v=3","gravatar_id":"","url":"https://api.github.com/users/almoghzn","html_url":"https://github.com/almoghzn","followers_url":"https://api.github.com/users/almoghzn/followers","following_url":"https://api.github.com/users/almoghzn/following{/other_user}","gists_url":"https://api.github.com/users/almoghzn/gists{/gist_id}","starred_url":"https://api.github.com/users/almoghzn/starred{/owner}{/repo}","subscriptions_url":"https://api.github.com/users/almoghzn/subscriptions","organizations_url":"https://api.github.com/users/almoghzn/orgs","repos_url":"https://api.github.com/users/almoghzn/repos","events_url":"https://api.github.com/users/almoghzn/events{/privacy}","received_events_url":"https://api.github.com/users/almoghzn/received_events","type":"User","site_admin":false},"created_at":"2016-01-13T10:14:49Z","updated_at":"2016-01-13T10:14:49Z","body":"Thank you so much for your quick answer!\r\nIt's seems to be working very well, thanks again.\r\n\r\nJust one clarification I need:\r\nHow can I tell what is it track ID of my media file (*.mp4).\r\nI used the mp4dash with \"property 1\" and it works just fine.
