With multilayer001.heic:
Before:
[hevc @ ...] Scalability type 2 not supported
[hevc @ ...] Ignoring unsupported VPS extension
[hevc @ ...] The following bit-depths are currently specified: 8, 9, 10 and 12 bits, chroma_format_idc is 0, depth is 0
After:
[hevc @ ...] Scalability type 2 not supported
[hevc @ ...] Ignoring unsupported VPS extension
[hevc @ ...] SPS 1 references an unsupported VPS extension. Ignoring
