Potential problem with avdec h264

[evaluat0r]

I'm observing the following when decoding RTP packets:

Specifically, does the following signal a problem with the gstreamer plugin
(running on Linux):

2018-01-24 07:41:29,738470 25332 [0x00007f0d23fff700]   error libav

gstavviddec.c:1339 gst_ffmpegviddec_video_frame() <avdec_h264-0>  after

Whereas I don't see this issue on MacOSX.
