That is not enough context. Either post some code snippets, or e.g. add
a GST_DEBUG_BIN_TO_DOT_FILE_WITH_TS to the bus error message handler
(check gst-launch source code for how to) and run your app with
GST_DEBUG_DUMP_DOT_DIR=$PWD ./myapp to check the caps on both sides of
the link where it fails.
