videorate problem

[Gofrane]

hello,

I ran this pipeline on order to play  this video with 15 framerate per second

gst-launch-1.0 -v filesrc location=big_buck_bunny_480p_h264.mov  !  qtdemux ! vaapidecode !  videorate  ! video/x-raw,framerate=15/1  ! vaapisink

but I got this error

libva info: VA-API version 0.36.0
libva info: va_getDriverName() returns 0
libva info: Trying to open /usr/lib/x86_64-linux-gnu/dri/nvidia_drv_video.so
libva info: Found init function __vaDriverInit_0_32
libva info: va_openDriver() returns 0
WARNING: erroneous pipeline: could not link vaapidecode0 to videorate0

thank you in advance

Does the pipeline work without the videorate and associated capsfilter element?

IIRC, older vaapidecode produce a format that is not in the list of
formats videorate supports. What version are you running ? Even in
latest, it's likely using videorate will reduce performance. To avoid
this, the vaapi "surface" format would need to be implement with
capsfeature (video/x-raw(VASurface)), or the surface format would need
to be added to videorate.
