booksplit splits but doesn't tag

[ttot1]

I’ve made sure to have installed all the requirements and have mimicked and compared my results with what I see in the video where Luke demonstrates the script https://www.youtube.com/watch?v=z_CcQhbwINU.

When I run the script with the following command:

sh .local/bin/booksplit.sh audiofile.m4a timecodes.txt

It seems to split the tracks but not tag them. The result is only a directory with the album name and .opus files, each named after a track in the album. But these are not the audio files the script is supposed to output, the script seems to ignore the inputted audio file, making an incomplete execution.

I could reproduce this, ffmpeg doesn't overwrite tags for .opus files but it does for other formats. If the tag is not set on the opus file, ffmpeg can set the tag, but not if it is already set to something else. A temporary solution is downloading the file to another format from yt-dlp or re-encoding the file to another format, but this seems like an ffmpeg issue. This also affects the tag script.

I have a bigger problem. I tried .m4a .webm .opus and always get an error

Invalid duration specification for ss: 00:00:00 {name of first chapter of playlist}

Do I missing somthing ?

Booksplit uses tabs rather than spaces. Replace all the spaces in the document with tabs and it'll work.

Because the "booksplit" script does not call the script "tag" to write the data. It can be added but I am not sure Luke wants that. So I won't open a PR for that, but I can share both modified scripts here as a workaround, if you need. I have modified the scripts and improved them a little bit, and can get this result now:

"tags.txt" looks like this (no tabs just space [HH:MM:SS title] )

00:03:01 David Graeber's BS Jobs 00:06:08 An example of a BS job in the German military
00:08:09 How many people have fake jobs?

I have also fixed this error @kmj9 mentions I think: "Invalid duration..." but the error I got at first was for the ending of the video. My modification allows the script to process the last track without specifying an end time. So you won't get an error for the last file.

Instructions:

• Prepare a tags.txt file (name can be whatever) | The format should be HH:MM:SS title

• Then download your video using "yt-dlp x 'your_URL'"

• Run the script: bookmark downloaded-file.webm tags.txt

• Then you will get results like mine.

booksplit.txt Delete ".txt" and make it executable. Place it inside "~/.local/bin"

tag.txt

Luke also says something like "I don't know why we should use -nostdin option with ffmeg."

The reasons are:

• Since the booksplit script reads user inputs like album/book title, artist/author, and publication year from the standard input, using -nostdin ensures that ffmpeg doesn't accidentally consume any of these inputs.

• Disabling standard input for ffmpeg helps avoid potential issues where the script might hang or produce unexpected results due to unintended input being consumed by ffmpeg.

• By using the -nostdin option, the script ensures that ffmpeg only processes the specified input files and doesn't interfere with the standard input used by the script itself.
