Encode H265 to hvc1 codec

Question

Here is the info of my source file:

I want to keep audio quality and just encode the video track so I use this command:

ffmpeg -i INPUT -c:a copy -c:v libx265 video-h265.mp4

This is the result:

But the codec of the video track is hev1 . I want it's hvc1

Answer 1

'hev1'/'hvc1' are code points used to signal different packaging of the stream in the container mp4 file. There is no change in the coding itself. It is possible to round trip between the two modes. Try with mp4box :

mp4box -raw 1 file.mp4 

This will extract the stream into a raw HEVC file.

mp4box -add file_track1.hvc output.mp4

This will reimport the stream using hvc1 if it can.
