If it plays properly (without showing an error or a "Converting" message), then the full transcode will be successful. mp4Īnd in case you aren't sure, you can always run the command above, press Ctrl + C after a minute, and try playing the resulting video file using Quicktime. What you should first try to do, is run the following command to check if the original video file has audio in the AAC format: ffmpeg -i -vcodec copy -acodec copy -pix_fmt yuv420p -tag:v hvc1 -movflags faststart. However, the command above reprocesses the audio, even it was originally encoded in the AAC format. Now, simply run the command on any HEVC/H.265 file you wish: ffmpeg -i -vcodec copy -c:a libfdk_aac -vbr 5 -pix_fmt yuv420p -tag:v hvc1 -movflags faststart.

Then, compile ffmpeg using the following commands: brew tap varenc/ffmpegīrew install varenc/ffmpeg/ffmpeg -with-fdk-aac Transcode on macOSįirst, install homebrew. Thankfully, we can use ffmpeg, the de facto multimedia encoder/decider, to swap the container without modifying the video data inside! However, we sometimes have to undergo a lossy conversion for the audio due to restrictions on the audio codec for the mp4 container. the file extension) for the video files are usually not supported by either the macOS or iOS native video player. Currently, many video sharing networks have converged on HEVC/H.265 as a standard as well, although with a caveat: the container (i.e. As we transition to HEVC/H.265 as an industry standard for video files, we should strive to ensure that they can be played back with hardware acceleration because: a) it preserves battery life, b) it doesn't require installing more apps or codecs, and c) it allows for smoother playback and scrubbing.
Since 2017, all Apple devices that have been released support hardware accelerated HEVC/H.265 playback.
