I dont see any caps from the pipeline. Is this working without videoscale?

Hi, Bernhard!

I try to use decodebin ! ffmpegcolorspace but the result is the same.

If i put text-overlay = false (active verbose) the video work but don't show
any info about fps. 

pipe:

gst-launch-0.10 -v souphttpsrc  user-id=admin user-pw=123qwe
location=http://192.168.0.216/pbhelper/stream.mjpeg? ! jpegdec !  videoscale
! fpsdisplaysink sync = true text-overlay=false

last-message (close pipe): last-message = "Max-fps: -1,00, Min-fps: -1,00"

Thanks!

Hi,

Are sure that your stream is not muxed?

Try to use decodebin ! videoconvert in place of jpegdec (I hope
videoconvert is available in 0.10, else use ffmpegcolorspace).

Hi!

I try the next pipe:

gst-launch-0.10 -v souphttpsrc is-live=true user-id=admin user-pw=admin
location=http://192.168.0.123/stream.mjpeg? ! jpegdec !  videoscale !
fpsdisplaysink video-sink= xvimagesink sync = 0

The pipe show a only frame frozen.

There is an error in the pipeline?

You can get the caps on the videoscale src pad, and the caps at the
sink pad, and compare the width, height, pixel-aspect-ratio.
