I would like to prepend and append some static images to video (each 3 seconds). In the end it should be as follows:
title-of-talk.png
sponsors.png
talk.ges
sponsors.png
volunteers.png
license-and-isbn.png
Can you please give me some suggestions how to implement this feature? I am trying to cut videos from open source conference.
I tried to add those images using ffmpeg, but the audio/video synchronization was broken in final file.
ffmpeg -y -nostdin -f concat -safe 0 -i "$tmp_filelist" -c copy ./video_out/$filename.mp4
I'm getting the following error with make-xges:

I've implemented the fix described in issue-741507162; the presentation doesn't inlude deskshare.webm.
Output of download.py when downloading /deskshare/deskshare.webm is now: HTTPError: 404. In my outdir deskshare.webm is 0 bytes.

I have many videos where the speaker has disabled the webcam feed so we just get a white box. I have tried setting webcam-size to 0 and that does hide it but the slides are still on the left side of the video rather than centred.
It seems some ges-launch-1.0 doesn't render it for some reason:

Some notes on what I have tried so far. I am not familiar with gstreamer and have only dabbled with python before so I am likely barking up the wrong tree on these things.
I have managed to parse the cursor.xml and make another layer which displays a png of a red dot in the right place at the right time. It takes a long time to process and something in the default compression settings causes a lot of artifacts. Also forget about importing it into Pitivi.
For vectors I thought I would look at using cairo and rsvg to create pngs of each element which are then added to a new layer. Hit a bump there as rsvg doesn't seem to accept an svg string, only a file or "raw data".
I have seen following exception:

I've tired to solve it on mine by just adding a "if start == end: continue" just before but I'm not sure if that's a good fix. Some of these take a very long time to process.

Hello. It's a nice repo but there's a problem. I can see the webcam at the top right of the screen. But the rest of the screen is black. I wondered if it was related to my recording and I tried a few other recordings and the situation is the same. When I looked at the image files created later, I saw that they were corrupt. There is no problem with SVGs, I checked them. I thought that the _render_slide method was causing corrupted PNG files, so I made some changes here, but I was not successful. Your help would be great.
