Hi all,

I am using WPT 2.16 and trying to get URL capture. My understanding is that the video rendering is server-side and I have enableVideo=1 configured in setttings.ini

After running the install check, it is reported that no test agents are configured for video. I am currently use wptdriver only. Do I need to still configure urlblast even in video processing was moved to the server in 2.16? Or am I misinterpreting something. I am not sure where to look. Many thanks to anyone that can offer guidance. Result of /install is as follows:

What happens when you actually try to create a video in a test?

My install of 2.16 renders video ok

Only difference with your install is

Code:
ffmpeg Installed with scale and decimate filters(required for mobile video): 1.2.6-7:1.2.6-1~trusty1,scale,decimate

Mine also shows "No Test Agents are Configured to Render Video" but I'm pretty sure this message was removed after 2.16 was released
I think I got it working. That was the clue.

So, here's the way I think it works. First, the "No test agents are configured to render video" messages is still there in 2.16. I added an agent for that through URLBlast, but still could not get video.

I could not get far enough into the code, but I am *guessing* that the server-side rendering engine that was used for mobile is now used for all video(?) Therefore, if ffmpg is not configured ALONG WITH the appropriate filters, it will not work. It's a guess.

Anyway, on the same machine (Ubuntu 12.04), I rebuilt ffmpeg. After that, /install shows the following:

Note the change:

After this, I re-ran some of the same tests are the video is working well. I have not fully walked through the functionality, but so far, so good.

Thanks for the help!
It looks like the issue is that the ffmpeg that comes with Ubuntu normally does not have lib x264 compiled-in and that is needed for server-side rendering. I have added a check for that post-2.16 which will hopefully help in tracking down the issue.
