Make Apple Vision Pro Compatible MV-HEVC Files with x265 and FFmpeg 7.1
In this article, we will cover the steps to encode side-by-side stereo video MV-HEVC using x265 and FFmpeg 7.1, making the files compatible with Apple Vision Pro. We will discuss key concepts, subtitles, and provide code blocks for proper formatting. By the end of this article, you should have a solid understanding of the process, and we will provide references for further learning.
What is MV-HEVC and Apple Vision Pro?
MV-HEVC (Multiview High-Efficiency Video Coding) is a video compression standard for encoding multiple views or stereo video. It offers efficient storage and transmission of 3D video while preserving visual quality. Apple Vision Pro is a hypothetical virtual reality or augmented reality headset by Apple, which we assume might not recognize the traditional MV-HEVC format.
Installing FFmpeg and x265 for MV-HEVC Encoding
To get started, install the latest version of FFmpeg (7.1 or higher) from the official website: https://ffmpeg.org/download.html. Compile FFmpeg with the x265 library, as MV-HEVC encoding is not natively supported by FFmpeg.
For x265 installation, consult the official documentation for your operating system:
# For example, on Ubuntu 20.04
sudo apt-get update
sudo apt-get install libx265-dev
Encoding Side-by-Side Stereo Video MV-HEVC using x265 and FFmpeg
Assuming you have two left (L) and right (R) video input files (e.g., left.mp4 and right.mp4) and wish to create an MV-HEVC output side-by-side stereo video:
ffmpeg -i left.mp4 -i right.mp4 \
-filter_complex "[0:v][1:v]hstack=inputs=2:shortest=1" \
-c:v libx265 -crf 29 -tag:v hvc1 -an output.mp4
This FFmpeg command:
- inputs left.mp4 and right.mp4 files
- stacked the videos horizontally (-filter_complex hstack)
- encoded the output using x265 library (-c:v libx265)
- set a constant rate factor of 29 (-crf 29)
- added hvc1 tag for MV-HEVC (-tag:v hvc1)
- disabled audio streams (-an)
- outputs the final video as 'output.mp4'
Compatibility with Apple Vision Pro
Considering Apple Vision Pro is hypothetical, these steps will make MV-HEVC files compatible with existing Apple devices and platforms (e.g., macOS, iOS).
- Installed FFmpeg and x265 for MV-HEVC encoding
- Encoded side-by-side stereo video with x265 and FFmpeg
- Ensured compatibility for Apple Vision Pro (hypothetical)
