Add hvc1 tag to codec and copy cover art for mp4 and m4v #127
Conversation
add hvc1 tag to codec so HEVC is playable by Quicktime in mp4 and m4v containers on MacOS. See https://danconnor.com/posts/21d8bd7c22f6ae6b423c3c09/how_to_encode_h_265_hevc_video_that_will_play_in_quicktime_on_macos_using_ffmpeg_
Copy second video stream assuming it is mjpeg cover art and map it to the output file.

Copy the second video stream assuming it is an mjpeg stream masquerading as cover art. |

Only do this for m4v and mp4 files, not mkv files. |

Workaround for ffmpeg not remapping channels for libopus automatically |

Sorry this is all a bit of a mess but it mimics what I've done in the compiled version on my Mac which works perfectly for the files I'm converting, which I've been using for the last six months. I also didn't realise that I had closed it last time I added a change I made. Attaching the file I edited on my computer that I used as the basis for the changes here, which I found at /usr/local/lib/node_modules/h265ize/h265ize but added .txt so it could be uploaded here. h265ize.txt |

It is only safe to map the first video stream. With your changes above (line 343) you can safely map a second stream, but not more than 2. Can you reduce this to only mapping the first 2 possible video streams.

Thanks for responding to my pull however I'm not exactly sure what you are suggesting here regarding mapping 2 video streams. But I'll explain my reasoning for mapping the second video track.
It appears that ffmpeg recognises cover art as a video stream. So for the video at https://d2qguwbxlx1sbt.cloudfront.net/TextInMotion-VideoSample-720p.mp4 from https://textinmotion.com/help/samples ffmpeg sees this as follows:

It's a failing of ffmpeg that seems to cause this, as recognised by https://superuser.com/a/1357462
