Description Nicola 2011-01-20 13:40:25 UTC
here is a leak in a pipeline such this:

rtspsrc location=.... ! rtph264depay ! ...

==14381== 459 (360 direct, 99 indirect) bytes in 3 blocks are definitely lost in loss record 3,928 of 4,029

Comment 1 Tim-Philipp Müller 2011-01-20 14:13:52 UTC
Tested with:

tpm@zingle:~/gst/git/gst-plugins-good/gst/rtp$ G_SLICE=always-malloc valgrind --leak-check=yes --num-callers=20 --suppressions=../../common/gst.supp ../../../gstreamer/tools/.libs/gst-launch-0.10 rtspsrc location=rtsp:// ! rtph264depay byte-stream=false ! fakesink -v

and fixed (albeit with wrong commit message):

    h264depay: don't leak codec data buffer in byte-stream=true mode [N.B. this should be byte-stream=false of course]
