Youtube videos missing quality options

[yinteresting]

Hi,

When I was running cefclient and browsing some youtube videos, I noticed that some videos are missing quality options. Only 360p is available. For the same video, on Chrome, it has many other options to select.

Just wondering if there is any parameter or setting that I can set to enable more options.

For example, the following video: http://www.youtube.com/embed/ZX9e-ZrnZI ... autoplay=1

Thanks in advance.

Most likely the libcef was not built with codecs support.

Most likely the libcef was not built with codecs support.

The problem is some videos have the same quality options as what Chrome offers. If there is no codecs support at all, my suspect is that all videos should be limited with 360p option.

Could also be the lack of DRM (Widevine) support causing YouTube to only offer very low-quality options.

Just to confirm, after setting proprietary_codecs to be true, I can see different video quality options now.
What confuses me is why other videos have all different options if H.264 are not supported.

With the youtube-dl tool you can check all formats available for a video. For your video it shows:
