[video_player_videohole] Problem playing widevine #599

MAUstaoglu · 2023-07-19T11:27:46Z

Problem playing widevine.
What works:
works fine - cenc mpeg dash content with public proxy
content https://storage.googleapis.com/wvmedia/cenc/h264/tears/tears_uhd.mpd
proxy https://proxy.uat.widevine.com/proxy?provider=widevine_test
works partialy - cbcs mpeg dash content with public proxy - it starts playing but it stops after some tim
content https://storage.googleapis.com/wvmedia/cbcs/h264/tears/tears_aes_cbcs.mpd
proxy https://proxy.uat.widevine.com/proxy?provider=widevine_test
doesnt't work
any widevine encrypted content created with shaka packager (which plays fine in shaka player web and on android)
cbcs not working
cenc not work
both mpd and HLS not working
How did we test:
create content by using shaka packager
put content on web
play it in shaka player demo (web browser)
play it on android
play it on tizen
ie. cd /var/www/html
package_wv /tmp/path/to/clear/mp4/video.mp4 ./video-encrypted
It will create both .m3u8 and .mpd files you can play over browser using above mentioned hls player

@MasterSon05 , I checked this problem on my TV, the cenc mpeg dash content works well, and cbcs mpeg dash content can not be played.
And I am not sure what do you mean about the following content.

any widevine encrypted content created with shaka packager (which plays fine in shaka player web and on android)
cbcs not working
cenc not work  =>  You saied cenc can work before, what do you mean?
both mpd and HLS not working  => Do you mean the cbcs of both dash and HLS are not work?

delacko · 2023-07-23T08:20:18Z

Hi,
we I tested this together with @MasterSon05 with video_player_videohole. Content plays or does not play based on shaka-packager version used.
All of this content works fine if one tests in shaka player demo (https://shaka-player-demo.appspot.com/demo/#audiolang=en-US;textlang=en-US;uilang=en-US;panel=CUSTOM%20CONTENT;build=uncompiled)

Device tested: UE43BU8072UXXH (2022 TV, basic model)

Does not work at all with either CBCS or CENC encrypted widevine for newer shaka packager

Shaka packager versions tested: 2.6.x, 2.5.x
Proxy used url used: https://cwip-shaka-proxy.appspot.com/no_auth
it does not work on either HLS or MPEG DASH
Error: PlatformException(Player error, Error: , null, null)

Works fine with both CBCS and CENC encrypted widevine for older shaka packager:

Shaka packager versions tested: 2.3.x, 2.4.x
Proxy used url used: https://cwip-shaka-proxy.appspot.com/no_auth
works both with HLS and MPEG DASH (even though this samsung page says it should work only with mpeg dash bot hls)

Clear stream packaged with and shaka packager:

they work fine both for HLS and MPEG dash.

How were the test samples made:

you need an input file and destination directory (stick to h.264 for video codec, aac for audio codec)
change in that script type of encryption - choose cbcs or cenc
change to destination directory, ie. cd /tmp/cbcs_output
download shaka packager binary from it's github releases page (https://github.com/shaka-project/shaka-packager/releases), chmod +x , note that newer version are statically build, for older you may need some additional binaries ie. apt-get install libatomic1)
ie to download version 2.6.1: wget -O /usr/local/bin/packager_2.6.1 https://github.com/shaka-project/shaka-packager/releases/download/v2.6.1/packager-linux-arm64
choose path to shaka packager version you want to use
run script: package_wv /sport.ts sport-cbcs
run web server in that directory, ie. caddy, http-server
serve file sport-cbcs.m3u8 or sport-cbcs.mpd to tizen player

bash script package_wv:

@MasterSon05 , about widevine https://storage.googleapis.com/wvmedia/cbcs/h264/tears/tears_aes_cbcs.mpd, I tested it on T-KSU2EBAKUC-0113.12 which version is near T-KSU2EBDEUC-1403.6, this problem can be reproduced, the widevine can be played a moment and stopped.

I checked the platform log, there is a decryption error of platform player. Currently we use mmplayer to implement video_player_videohole, I tried to use plusplayer and this widevine can be played successfully.
You can try this plugin https://github.com/hyue7/plugins/tree/video_player_plusplayer/packages/video_player_plusplayer, but plusplayer is not published, so it need the partner certification when build app.

wanchao-xu · 2023-08-03T07:50:00Z

@delacko , I tested the samples which you provided, HLS samples are same as you saied, the encrypted widevine which generated by shaka packager 2.5/2.6 can not be played. But the MPEG dash samples has some problems, all MPEG dash samples can not be played by shaka player and video_player_videohole.
I can not use shaka packager because https://license.uat.widevine.com/cenc/getcontentkey/widevine_test can not be connected. Could you check the MPEG dash samples is right or not?

When I get a build with a partner certificate, I can play the videos in the example application without any problems.
Although widevine works in the example app with the partner certificate. The ones we tried with Shaka 2.5.1 and 2.6.1 packer did not work. It seems to work fine with the 2.4.x packer. But I guess it doesn't work with a higher packer version. And it is irrelevant if we use mpeg dash or HLS.

@wanchao-xu you should use this proxy when playing: https://cwip-shaka-proxy.appspot.com/no_auth
When creating content with shaka packager you should use this as key server: https://license.uat.widevine.com/cenc/getcontentkey/widevine_test

So the url https://license.uat... is the url you pass to shaka packager in command line argument --key_server_url

Both of these are always available as they are widevine's public test resources. Those samples of content I made will work only with this public widevine proxy using widevine provider widevine_test. (if you have a private widevine proxy it will not work)

How to play widevine samples:

build an app which will play url together with appropriate widevine proxy
sign the app with partner certificate key
run app on tizen tv

Example of combination that works:
widevine mpeg dash url made on shaka packager 2.4.1: https://devel.uniqcast.com/wv/samples/bbb_cenc_2.4.1/bbb_cenc_2.4.1.mpd
widevine proxy: https://cwip-shaka-proxy.appspot.com/no_auth

Example of combination that does not work:
widevine mpeg dash url made on shaka packager 2.6.1: https://devel.uniqcast.com/wv/samples/bbb_cenc_2.6.1/bbb_cenc_2.6.1.mpd
widevine proxy: https://cwip-shaka-proxy.appspot.com/no_auth

delacko · 2023-08-08T11:22:24Z

We tested plusplayer and videohole (mmplayer).
They behave completely the same.
For shaka packager 2.4.1:

videohole player works for all of these: mpeg dash widevine, HLS widevine and clear stream
plusplayer works for all of these: mpeg dash widevine, HLS widevine and clear stream

For shaka packager 2.6.1:

videohole player doesn't work for mpeg dash widevine, doesn't work for HLS widevine, but works for clear stream
plusplayer doesn't work for mpeg dash widevine, doesn't work for HLS widevine, but works for clear stream

I have attached table showing our tests.

We also tried to test tizen HTML app - on that app all these urls work with hls.js player.
Meaning whatever problem exists here - it does not exists in Tizen Web apps using MSE/EME - which hls.js uses.

xuelian-bai · 2023-08-18T00:55:34Z

@delacko I'm sorry that for now we can't support shaka packager 2.5.1 or higher, since there is some difference in fmp4 segments. We may support this in the future, if you really need this feature in your product, please send me mail to talk about this([email protected]).
The reason that Tizen Web app which using hls.js player can work is, hls.js player parse container by itself, Chrome didn't call platform player like flutter plugin did.

delacko · 2023-08-18T07:05:38Z

@xuelian-bai do you have any details on what changed in mp4 between shaka packager 2.4 and 2.5+ (ie. if you know some mp4 box information missing, or similar problem). If we knew this information I believe we could patch shaka packager 2.6 to make this work.

2.4.x was stopped being developed in 2020. Most encoder companies and all almost all small companies using vod and live on widevine use shaka packager to package their content for widevine, so I expect we will see see this problem very often.

We also tried to encrypt content for widevine with mp4encrypt (from bento4 project) - it is also working fine for widevine on all other devices but not on Samsung. My guess is that a lot of Widevine packagers out there are not compatibile with fltuter-tizen widevine player.

For us this means that for all project requiring widevine we need to use HTML app with hls.js for Samsung TVs and cannot go with much faster and nicer app using flutter-tizen.
HTML5 app for same Samsung TVs using hls.js (extension over HTML5 video player) works with all widevine packagers we tried.

xuelian-bai · 2023-08-18T08:48:18Z

hmm. Now I know about the situation, as you know, this issue couldn't be fixed in flutter-tizen plugin side, we need to talk with platform team about this, I will get back to you then.
For more details, for example, in 2.5.1 the fmp4 segments have the multiple PSSH (2), one contains the system id of widevine and another contains the common system id, but we expect only one system id.

hyue7 · 2023-09-14T10:01:38Z

Hi,all!
We have fixed the issue about hls+cbcs, hls+cenc generated by shaka-packager. But you need wait OTN for fix this issue, however, we are not sure when the OTN will be scheduled.
By the way, we are doing update of videohole plugin based on mmplayer and plusplayer, plusplayer support more features, and you don't need wait OTN for fix issues.

MAUstaoglu · 2023-09-14T14:57:19Z

Hello, thank you for the fix. When does the prediction become testable? Will you also add plusplayer to the videohole plugin or will there be a new plugin like video_player_plusplayer?

hyue7 · 2023-09-20T03:04:11Z

Hi, plusplayer will be added to video_player_videohole this week or next week, and the you can test~
