Quick start on HTML5 video player code please. What source files do I need to focus on?

[roschler]

I'm just about done setting up the chromium and depot_tools elements so I can build Chromium and modify the HTML5 video player code.  The Chromium code base is vast and if I could know what are the main source files that implement the HTML5 video player, that would be a big help in streamlining my efforts.

Can someone give me a jump start on what source files I need to focus on to start my project?

First, chromium-dev or blink-dev are more likely to be the right groups for this discussion, depending on your intention, as chromium-html5 is about web development than browser development.

Do you want to modify the user facing appearance of the video player (the controls, play, pause, they location, colors, images and so on), or do you want to modify its guts (add support codecs, add support for more streaming options, add support for filters/mixers)?

The former is in Blink (start here) and the latter is in Chromium (start here).

cs.chromium.org is generally a very useful tool for browsing the code and following code paths.

Hi Phistuck,

>> The former is in Blink (start here) and the latter is in Chromium (start here).

Currently I'm facing a more basic problem with the "gn" command (Ninja?) looking for cdb.exe in what appears to be the wrong directory.  Which group is the best group to ask about that problem?  It looks like "gn" is expecting a different version of the Windows SDK to be installed than the one I have, since cdb.exe does exist in a different directory:

IOError: [Errno 2] No such file or directory: 'C:\\Program Files (x86)\\Windows Kits\\10\\Debuggers\\x64\\cdb.exe'

ERROR at //build/toolchain/win/BUILD.gn:39:3: Script returned non-zero exit code.

Directory where cbd.exe is located:

C:\Program Files (x86)\Windows Kits\8.1\Debuggers\x64\cdb.exe

I believe the Windows 10 SDK must be used. Did you follow the Windows build instructions?

chromium-dev is the right group for general build issues.

Hello Phistuck,

I did but I missed the part about the Windows 10 SDK, thanks!  Downloading and installing that now.
