Hi there! Ive downloaded some videos using this 3-step method (aac + mp4 video + merge) but when I play them, it freezes all the time.

Im using an iMac 4K. but it freezes on iPad Pro, too.
Thanks.

Some of the videos play properly at 4K on QuickTime Player, and some of them don't. VLC is actually one of the players I found that plays them correctly. Could be a lack of CPU horsepower. I'm not sure what Apple is doing on the newer videos when they author them that enables them to play better. You could go down to 1440p and see how that works out.

Thanks. CPU is at 10% or 15%. And I can even play 8K videos with no issues. Tried on QuickTime and VLC.

Oh sorry! I just remembered what's causing your problem. Update FFmpeg to the latest version and redownload the video you're trying. I had this issue when I first started because I was on an older version of FFmpeg.

okay! That could be the reason, because Ive just tried to convert it to lower resolution (720p) using Handbrake, and the output video freezes too.

Finally, I was able to download MP4 + AAC and merge them successfully.
Followed this tutorial on installing latest FFMPEG 4.3.2 on Debian https://www.osradar.com/install-the-latest-version-ffmpeg-ubuntu-debian/

Thanks.

Cool! 👍🏼
