The test result is unchanged because it considers only the decoded output. This
change affects only the demuxer and not the decoder. So the decoder output
remains unchanged. I didn't realize that when i submitted this patch, my bad.
I have now changed the test to compute the CRC taking the side_data into
account. I'll upload that patch shortly.
