--- Comment #14 from Guillermo Rodriguez <guillerodriguez.dev at gmail.com> ---
Just stumbled upon this one.

The following pipeline results in a sluggish 1 fps playback (source stream is
approx 10fps):

gst-launch-1.0 souphttpsrc is-live=true location=... ! jpegparse ! avdec_mjpeg
! autovideosink

This works fine:

gst-launch-1.0 souphttpsrc is-live=true location=... ! image/jpeg,framerate=0/1
! jpegparse ! avdec_mjpeg ! autovideosink

I too believe that jpegparse should default to 0/1, and not 1/1, if the source
does not set the framerate.
