Hi, All:
When turning ENABLE_ENCRYPTED_MEDIA_V2 on, build break occurs for
webkitgtk-2.8.0 release (webkitgtk-2.8.0.tar.xz), and the detailed information
is at end of mail.
Does it mean the we still have the following two issues for support EME in
webkitgtk-2.8.0 release?
1. The build system still need some change to fix the build break when
enabling ENABLE_ENCRYPTED_MEDIA_V2.
2. The EME related implementation for gstreamer
(WebCore\platform\graphics\gstreamer) may still NOT be done.
Please also help to answer the additional questions for EME support:
A. Which port of webkitgtk-2.8.0 already supports
ENABLE_ENCRYPTED_MEDIA_V2, EFL, MAC, or windows?
B. Whether it is easy to fix the above possible issue 1 and 2, and is there
any change list we can refer from other port?
C. Have we fixed the above possible issue 1 and 2 in the latest code of
webkitgtk? Or, do we have any plan to do it?
D. For support EME in webkitgtk, is there any other issue except the above
1 and 2?
Thanks a lot.
//Detailed information for build break
* Enable EME by turning it on in the following 2 files:
./Source/cmake/OptionsGTK.cmake:WEBKIT_OPTION_DEFAULT_PORT_VALUE(ENABLE_ENCRYPTED_MEDIA_V2
ON)
./Source/cmake/WebKitFeatures.cmake:
WEBKIT_OPTION_DEFINE(ENABLE_ENCRYPTED_MEDIA_V2 "Support EME v2" ON)
* The build error is as below, which should AT LEAST mean the necessary
EME-related idl files are NOT added to the build system in webkitgtk-2.8.0.
