Marco Arnulfo c1b1e86046 fix(codecs): in-band parameter sets compare without trailing zero bytes (fixes #1483)
ffmpeg keeps a trailing zero byte after the hvcC PPS that the in-band PPS lacks, so the byte-for-byte comparison read it as a parameter-set change and sent the stream to the software decoder from its first sample. A NAL unit never ends with 0x00 (H.264 7.4.1, H.265 7.4.2): those bytes are trailing_zero_8bits, so both sides are compared without them. The platform fallback test used a trailing zero byte as its changed SPS; it now changes nal_ref_idc.
