--- Comment #15 from Julien Isorce <julien.isorce at gmail.com> ---
Just to confirm, does it happen only on the attached i-frames-non-frag.mp4 or
there are mp4/h264 that succeed ?

It could fail here
https://cgit.freedesktop.org/mesa/mesa/tree/src/gallium/state_trackers/va/picture.c#n149
max_references is set here
https://cgit.freedesktop.org/mesa/mesa/tree/src/gallium/state_trackers/va/picture_h264.c#n114
so is gstreamer-vaapi setting
libva::va.h::VAPictureParameterBufferH264::num_ref_frames correctly ?
