# build_all_vp9_file_decoder_conformance_tests is currently false by default.

# The self-contained variants of these tests rely on having enough flash space
# for the whole input file, and running more than one large test per pave will
# tend to fail due to insufficient flash space (at the moment).  Still, for
# debugging it's useful to be able to run this way, especially since re-building
# the code doesn't require re-copying the input file blob whose hash hasn't
# changed - and building tests this way avoids relying on a local http server.
#
# For automated testing, we instead use vp9_decoder_conformance_test__http
# (single target), which will fetch a .ivf file from a local http server and
# output it's MD5 hash to stdout.  That target is driven by e2e test script
# running off-target that scrapts stdout for the MD5 and deteremines e2e test
# success/failure in the e2e test script, not on the target.
