I have an app which stream videos, now my new feature is to save that videos for offline view. I saw offline feature of hotstar, when we save offline video hotstar save video spit as some chunk.ts format, it will be saved on corresponding andriod folder of hotstar, how can i achive this I search web but did not get any proper info how to implment this. when I search for chunk.ts I got some github data https://github.com/AndyA/ts-split

which is in pearl, so when I saw I had doubt like this should done on serverside and when we download the files will downloaded from server. can any one give an expert suggetion regarding this.

Thank you

  • why can't you just download the video (file) to the device directly? – user1 Apr 24 '18 at 08:06

  • could you do something similar to what youtube does? they download the file as exo but encrypt it, so it won't be played by other media players, so i suggest you find a suitable encryption mechanism to your need, and download the video, then decrypt the file to play it, this [answer](https://android.stackexchange.com/a/114173) provides good insight that i suspect would help you get started – user1 Apr 24 '18 at 09:49

one way to achieve this would be to use a CipherOutputStream and encrypt the files as they are downloaded check CipherOutputStream

also refer to this questions, and this question on how to encrypt and decrypt. and for rendering the videos, you would have to decrypt the files as you play them
