Encoder tests currently do not dump recon as ihevce_plugin doesn't yet support recon dump.
This will be enabled once the recon dump is supported.
Decoder tests currently validate just a few files from big buck bunny.
Use "ctest" run all the tests when using cmake.
This downloads the required media files and uses them in the tests.
If running the tests directly using the test binaries, then download the media files
and export HEVC_TEST_DIR to the extracted folder before running the binaries directly.
