2 valgrind outputs to compare failure case with working reference case

Failure:
LIBVA_DRIVER_NAME=gallium valgrind --tool=mmt --mmt-trace-nouveau-ioctls
--log-file=va_mesa_bin.log gst-launch-1.0 filesrc
location=/home/SERILOCAL/j.isorce/Downloads/centaur_2.mpg num-buffers=6 !
mpegpsdemux ! mpegvideoparse ! vaapideco^C ! tee ! vdieoconvert ! xvimagesink

Success:
LIBVA_DRIVER_NAME=vdpau valgrind --tool=mmt --mmt-trace-nouveau-ioctls
--log-file=va_over_vdpau_mesa_bin.log gst-launch-1.0 filesrc
location=/home/SERILOCAL/j.isorce/Downloads/centaur_2.mpg num-buffers=6 !
mpegpsdemux ! mpegvideoparse ! vaapidecode ! tee ! videoconvert ! xvimagesink

Where should I look at in these 2 logs to compare what contain the nouveau_bo
buffer between the first st/va being/end frame ? (using demmt -l)
