x265enc: "error: Encode x265 failed."

[Christoph Kuhr]

Hi *,

I am trying to encode some single images to a x265 transport stream.


My pipeline:

gst-launch-1.0 --gst-debug-level=3 multifilesrc
location="/home/christoph/GStreamer/rectTest/rect_3840x2160-200x200_%d.png"
start-index=1 stop-index=359  do-timestamp=true
caps="image/png,framerate=\(fraction\)50/1" ! pngdec ! videoconvert !
videorate !
video/x-raw,framerate=\(fraction\)50/1,width=3840,height=2160 ! x265enc
tune=6 speed-preset=9 log-level=4 ! video/x-h265 ! h265parse ! mp4mux !
filesink location=rect_2160p50.mp4
`

The Standard Output:

My guess is that I have to provide a VPS header after `pngdec`.

Do you agree?
How would I do that?

Thanks for any help!

Best,
