After the protection event support will be added in the bug 185245 the fucntion MediaPlayerPrivateGStreamerBase::handleProtectionEvent will be reached, so we should remove the ASSERT_NOT_REACHED.
Created attachment 339814 [details] Patch
I think I explained myself poorly when I asked you to have this part of the code in a different bug. I meant that you should add the code to dispatch the event in a different bug other than the one for bug 185245. Would you have time to do it here?
The bug is renamed from "Avoid a crashes after the protection event support is added in 185245" to "Dispatch the protection event from AppendPipeline to MediaPlayer" because I have removed the code which dispatches the Protection event from bug 185245 to this one.
