<p>I am using FFMpeg to compress a video to X265/HEVC. When I am doing it normally the converted video doesn't working on iPhone or iPad. But while I am using the tag - &quot;-tag:v hvc1&quot; in the command. Now the output video working fine. So what does the tag means? and what's the pros and cons of using this tag?</p>
<p>Lastly, form where I can get these tags and command easily?</p>

The [FFMpeg document](https://ffmpeg.org/ffmpeg.html) gave the idea of using the tag option with a FourCC code, and [H.265/HEVC Video Encoding Guide](https://trac.ffmpeg.org/wiki/Encode/H.265) gave the idea of *Final Cut and Apple stuff compatibility*. The hvc1 is defined to support Apple devices.
