Regarding CEF3 print support

[giridharb54]

When is the print support for cef3 going to be released??? I want to use CEF with my application which one to use CEF1 or CEF3?? Is the migration from CEF1 to CEF3 easy????

Printing support on Windows is currently under review: https://code.google.com/p/chromiumembed ... ail?id=505. CEF1 is no longer actively developed so you should use CEF3.

HI,

We are planning to use CEF3 in our product..Print is an important feature for us.Can you please share the approximate timeline for the below features??

Printing support
Search/find support
Response filtering
Modal dialogs
HTML5 audio/video support

Also can we use the patch in this link http://code.google.com/p/chromiumembedd ... ail?id=505 ??? Are there any issues using this???

Regards,
Giri

Response filtering is already possible (with a workaround) see comment #6 in Issue 515:
https://code.google.com/p/chromiumembed ... ?id=515#c6

I've implemented this workaround in CEF Python and it works fine.

HTML5 audio and video is supported, but some formats (MP3, AAC, H264, MPEG-4) aren't supported because of legal issues,
see comment #7 in issue 371:
https://code.google.com/p/chromiumembed ... ?id=371#c7

Last time I checked the support was as follows:

Video support
Open http://html5test.com/ in CEF 3 and go to video section, results as of cefpython3 v0.12:

video element - Yes ✔
Subtitle support - Yes ✔
Poster image support - Yes ✔
MPEG-4 support - No ✘
H.264 support - No ✘
Ogg Theora support - Yes ✔
WebM support - Yes ✔
Audio support
Open http://html5test.com/ in CEF 3 and go to audio section, results as of cefpython3 v0.12:

audio element - Yes ✔
PCM audio support - Yes ✔
AAC support - No ✘
MP3 support - No ✘
Ogg Vorbis support - Yes ✔
Ogg Opus support - No ✘
WebM support - Yes ✔

Printing support will land early next week for 1650+. Search/find will be added some time soon.

Thanks magreenblatt and Czarek !!.Your information helped us a lot.One more thing i would like to bring in here, performance is a key focus in our product and everywhere.I manually tested for performance by loading pages in CEF1 and CEF3,I couldn't find much difference in performance. I went through the codebase and found that there are some APIs for performance test,could you please share some docs on how to use these apis for performance testing?? or share the performance numbers or statistics compared to other browsers upon which we can conclude our decision to use CEF3.

See the "CEF3" section of http://code.google.com/p/chromiumembedd ... chitecture for why CEF3 is better than CEF1. Any performance benchmark results that apply to Chrome also apply to CEF3.

Hi,

We are on the process of integrating CEF3 in our product, but there were some concerns regarding security. I mean upon loading some malicious javascript in CEF3 ,can someone access our product data?? how to handle this security threat???.Please let us know if there are any other security threats which we need to handle or know about.
