Public bug reported:
After an upgrade from Ubuntu 16.04 to Ubuntu 18.04, videos in pdfpc do not show
image any more, only sound. I have created a minimal test case here (please
fetch both the PDF and the mp4):
- http://stephane.magnenat.net/~steph/bug-pdfpc/bug-pdfpc.pdf
- http://stephane.magnenat.net/~steph/bug-pdfpc/gtc-studentgames-2018.mp4
The sources being:
- http://stephane.magnenat.net/~steph/bug-pdfpc/bug-pdfpc.tex
- http://stephane.magnenat.net/~steph/bug-pdfpc/video-title.png
Videos in the PDF play properly with other viewers, such as Okular, and
also directly with gtc-play, and even with a vaapi chain: `gst-
launch-1.0 -v filesrc location=videos/gtc-studentgames-2018.mp4 !
qtdemux ! vaapidecodebin ! vaapisink`.
Here is the log of pdfpc when launched with `export
