Re: [v8-users] Arraybuffer
Ok but then can someone give me a big picture of the directories ? And how the code is generally structured ? Or how is ArrayBufferBuilder:append called ?

This mailing list is about V8 itself, not arbitrary consumers (there are many) of V8. Do you understand the difference? V8 has no notion of "tabs", "WebKit", "renderer process", or "UI".

Re: [v8-users] Arraybuffer
This is how I see it atm
Each tab is a process that is composed of several threads, this process is
sandboxed with the Windows kernel security ( on Windows )
Then we have WebKit which is the rendered thread inside of this main tab
(thread) which as the name implies will render the page.
When in the renderer process is v8 called ?
Or when WebKit is executing UI things v8 is also running JavaScript code ?
Last thing is when ArrayBufferBuilder:append is called ?

Re: [v8-users] Arraybuffer
Not sure where to start with this message
a) Not even vaguely related to the original topic, you should start a new
thread when the topic is wildly different.
b) Do not start a new thread.
c) This code is from libav (or actually, maybe ffmpeg). av_XXX are macros,
functions and other values. The AV prefix is a hint to the user (you) that
it's part of the av library. AV stands for audio/visual (or I suppose,
audio/video these days)
d) This is a question that should be on www.stackoverflow.com
e) Please do not reply to this message. (at least regarding this new topic)
