Currently, on webOS TV 5.0, the Accept-Language request HTTP header cannot be set by your app. Even if your app sets the Accept-Language request header to a certain language tag, the actual header that is sent will be the language tag of the system language setting. Thus, we recommend that you do not use the Accept-Language request header on webOS TV 5.0 and handle the language and locale in an alternative way.

webOS TV 5.0 supports the AudioTrack API that mutes and unmutes an audio track. If your app does not play a sound while your content is playing, you should check whether to set the AudioTrack API correctly. If you set the enabled property of the API to false, the audio is muted. To play the selected audio track, you MUST set the enabled property to true. The following example shows how to set the property to true. You can check the value of the enabled property on the browser console as below. video.audioTracks[0].enabled For more information and examples about the AudioTrack API, refer to the MDN documentation below. https://developer.mozilla.org/en-US/docs/Web/API/AudioTrack

There has been an announcement from GlobalSign certificate authority regarding R1 deprecation and migration scheme to R3 and R5. https://support.globalsign.com/customer/portal/articles/2970034-globalsign-ssl-products-intermediate-and-root-changes This means that the R1 certificate will be no longer issued when it comes to be renewed after 27th. May 2019 instead it will be replaced with R3 and R5. We had compatibility concern with old legacy smart TVs when R1 has been replaced by R3 or R5 therefore deduced simulation test with the following results. Case 1. R1 replaced with R3 We had the best result and no compatibility issues in this case Case 2. R1 replaced with R5 Some old legacy Netcast models have compatibility issues but okay with entire webOS TVs. Alternatively, some partners configure their server by combining between R3 and R5 certificate as below and we have no compatibility issue in this scenario. Case 3. R3 combine with R5 Server configuration – When the device supports ECDSA cipher suite, it refers to R5 otherwise R3. In summary, if your server has the R1 certificate from GlobalSign and about to renew then please consider LG’s stance. We prefer Case 1 and alternative Case 3 rather than Case 2. We appreciate your cooperation in advance and directly contact nathaniel.kim@lge.com if you have any other technical inquiries.
