ffmpeg copy chapters from one file to another

If you are recording a 5.6k 360 video on a GoPro MAX you are going to fill up 4GB pretty quickly (in about 8 minutes). Back in Windows 95 days, that seemed pretty huge.

So nearly all consumer devices aim to be compatible with FAT32.īut FAT32 has a limitation hardcoded into it: the maximum file size that it can handle is 4GB. Whether you are using Windows, Mac, or Linux, a FAT32 external hard drive or thumb drive or memory card should work. That last point is crucial, because it means that you can put your memory card in pretty much any computer and be able to read it without having to install extra software.

Nevertheless, it has things going for it: it is reliable, it offers solid performance, and, most importantly, it is very widely compatible. Microsoft first rolled it out with Windows 95 and therefore it lacks some of the sophistication and features of newer file systems such as exFAT. Earlier models use smaller chapter sizes.Ĭhaptering serves an important purpose to ensure compatibility with the filesystem used on your memory card.īy far the most widely compatible filesystem these days is known as FAT32 (for 32-bit File Allocation Table).įAT32 is quite old. Newer GoPro cameras use chapters with a maximum size of 4GB. This is because of chaptering employed by GoPro cameras. Precisely how long the chunks are depends on the video mode and camera you are using. If you have ever recorded longer sections of video on your GoPro camera, you will have found that the video gets split up into smaller segments. > does not have the solution you require.Use ffmpeg to create full length GoPro footage which retains full GPS information. > I think best support for MPEG4 chapter handling is with MP4Box but it > I think ffmpeg support of chapter marker for mPEG4 file is limited. > felt they weren't used much in audio except for audiobooks. > needed to be part of MPEG4 support in LMS but after looking around I

> I briefly looked at chapter markers in MPEG4 in relation whether they I remember, that an m3u accompanying the audio (in my case after extraction as aaa, converted to Flac) would be one option, but I would be open (and prefer) the splitting into individual files. I do not think I think I really need m3u files, but I would like to have the 5 hour concert marked / split into individual tracks so that I can access the individual tracks.
