AW: AW: Change aspect ratio without transcoding?

[Bernhard Graaf]

Hi Martijn,

have you tried something like 'videoscale'? I've never used this element
before, but it's seems to help for fixing your problem.
In other case you should decode/encode the stream into the needed format.
Sorry.....

Ah, sorry, I should have mentioned that. We don't actually play the video
with Gstreamer. We're using a tcpserversink to serve the stream to our
distribution network.

I'd like the AR of the video to be 16:9 before that. Unfortunately, the
input (an analog-to-h.264 encoder) only supports 4:3 for the available
signal, even though the source is 16:9.

Best regards,
Martijn Grendelman
