8 years ago - When using DRM, you need to make sure the player is configured to use the correct license server. You'll most likely need to modify
WidevineTestMediaDrmCallbackto make it hithttps://license.uat.widevine.com/cenc/getcontentkey/widevine_test, since that's not its default. In ExoPlayer V2 this can be configured where you add the sample to the demo app. - We'd need a full bugreport captured from second phone shortly after attempting playback in order for us to tell you for sure why the playback isn't successful.

Issue:
I made a widevine protection video file(mp4) use shaka-packager (https://github.com/google/shaka-packager), and build my own server to put the video and mpd on it. When I add my own code in demo of exoplayer and play my video, playback failed. The status of player changes ether from preparing to idle or from preparing to end, while when I play videos in demo, I find that the status changes from preparing to buffering , then to end.
Issue reproducing:
2.Get a video (huoguo.mp4) and change it to widevine protection, using command: cd ~/shaka-packager/src/out/Debug
./packager input='huoguo.mp4',stream=video,output=huoguoen.mp4 \ --enable_widevine_encryption \ --key_server_url "https://license.uat.widevine.com/cenc/getcontentkey/widevine_test" \ --content_id "3031323334353640" \ --signer "widevine_test" \ --aes_signing_key "1ae8ccd0e7985cc0b6203a55855a1034afc252980e970ca90e5202689f947ab9" \ --aes_signing_iv "d58ce954203b7c9a9a9d467f59839249" \ --output_media_info
./mpd_generator \ --input "huoguoen.mp4.media_info" \ --output "huoguoen.mpd"
Finally, huoguoen.mp4 and huoguo.mpd can be generated. And huoguoen.mp4 can playback well at first 10s using pre-installed video player(without a widevine license server url).
3.build self simple server: Use a phone (marked as phone1) which can run as root ,and open 8080 as httpd service: adb shell busybox httpd -p 8080 -h /sdcard/www/
Then, push huoguoen.mp4 & huoguoen.mpd to /sdcard/www/: adb push /path/to/huoguoen.mp4 /sdcard/www/ adb push /path/to/huoguoen.mpd /sdcard/www/
Then, use another phone (marked as phone2) to playback the video huoguoen.mp4.
Phone1 and phone2 connect to the same wifi, and we can get the ip address of phone1 (e.g.192.168.1.2).
To verify connection well: Using phone2's browser, we input and goto http://192.168.1.2/huoguoen.mp4. The video can playback well at first 10s using pre-installed video player.
4.add this video source to exoplayer Get the source of exoplayer and make a self new project usting the demo. In samples.java, add codes:
private static final String WIDEVINE_GTS_MPD1 = "http://192.168.1.2:8080/huoguoen.mpd";
public static final Sample[] LOCAL = new Sample[] { new Sample("huoguoen", "3031323334353640","widevine_test","http://192.168.1.2:8080/huoguoen.mpd", Util.TYPE_DASH), new Sample("huoguoen1", "3031323334353640", "widevine_test", WIDEVINE_GTS_MPD1, Util.TYPE_DASH), };
In SampleChooserActivity.java add codes: group = new SampleGroup("local"); group.addAll(Samples.LOCAL);
5.build and run, after installed the apk, the main activity has a new list: -local ----huoguoen ----huoguoen1
6.playback the video added by my self: click the huoguoen or huoguoen1, the palyer can be display.
Question: The state of player chages from preparing to ended. The video do not playback .
