Changing Frame Rate

[ht techdev]

Hi

Is there a way, within gst-launch, to change the frame rate on fly? Failing
that is it possible to append to an existing encoded file, using a different
rate:

 

gst-launch-1.0 videotestsrc is-live=true num-frame=10 !  video/x-raw,
framerate=\(fraction\)"30/1" ! \ ! x264enc ! filesink location=t.mp4

gst-launch-1.0 videotestsrc is-live=true num-frame=10 !  video/x-raw,
framerate=\(fraction\)"50/1" ! \ ! x264enc ! filesink -append location=t.mp4

Cheers,
