Crash because the content follow the full-sample encryption, thus the subSamplesBuffer is nul
So we crash in this line:
>Source/WebCore/platform/graphics/gstreamer/eme/WebKitClearKeyDecryptorGStreamer.cpp:240
GstMapInfo subSamplesMap;
gboolean subsamplesBufferMapped = gst_buffer_map(subSamplesBuffer, &subSamplesMap, GST_MAP_READ);
