Av1ObuUtil

java-static fun maybeRewriteAv1MetadataObus(buffer: ByteBuffer!): Unit

Rewrites all ITU-T T35 metadata OBUs from the buffer that are not HDR10+. This is done to prevent the decoder on older SDK versions from misinterpreting them as HDR10+ metadata. If a non-HDR10+ metadata OBU is found, buffer will be rewritten with that metadata OBU marked as an unknown metadata OBU. If no non-HDR10+ metadata OBUs are found, buffer will remain unchanged. In either case, the position() and limit() of the buffer remain unchanged. This function is needed only when using MediaCodec on older SDK versions and is not necessary for other AV1 decoders.
