I've looked at the code, media_codec.configure() is fail safe in Android,
returns void. But encoders seems not to set INFO_OUTPUT_FORMAT_CHANGED if the
format configure was altered. As a consequence, you HW driver (Exynos) which
likely does not support High profile, changed it back to baseline and GStreamer
didn't notice.

Perhaps you may try to force a call to getOutputFormat() after each set_format()
? Though, I'm pretty sure what you are asking from you Exynos encoder is not
possible.
