Just in case nobody had noticed yet, there are actual differences in the limitations of what you can do with the streams in the container between 'hev1' and 'hvc1'. Quoting 14496-15: - "For a video stream that a particular sample entry applies to, the video parameter set, sequence parameter sets, and picture parameter sets, shall be stored only in the sample entry when the sample entry name is 'hvc1', and may be stored in the sample entry and the samples when the sample entry name is 'hev1'." - "When the sample entry name is 'hvc1', the default and mandatory value of array_completeness is 1 for arrays of all types of parameter sets, and 0 for all other arrays. When the sample entry name is 'hev1', the default value of array_completeness is 0 for all arrays." So yea, HEVC1 let us do a lot of stuff including putting parameter sets in-band, while HVC1 specifically notes that we don't have anything like that in-band.
