Need to set the file name and can download in mp3 as you tried but it will still be in the mp4a codec. Not sure if that matters to you. Your title is all weird and it includes the file path. Probably why link.title is not working. Try the below code to strip the title and the file path.

The 8k video you are trying to download uses AV1 https://en.wikipedia.org/wiki/AV1 https://aomediacodec.github.io/av1-isobmff/#codecsparam coding format

To better understand it, video codec av01.0.16M.08 means the following

• av01 is the AV1 codec
• 0 indicates Profile 0
• 16M indicates level 6.0 identifier 16
• 08 indicates an 8 bit bit depth

The key is in the level identifier 16 (6.0) A level 4.0 decoder can decode 1080p video @30fps but it won't be able to decode 1080p@60fps and it requires level 4.1 Similarly for 4k@30fps we need level 5.0 and 60fps need level 5.1 and 8k requires a level 6.0 or higher

Refer below for more information about these levels

https://en.wikipedia.org/wiki/AV1#Levels

Level 7 has not been defined yet.

You can see that some of these levels are fairly new as 8k is yet to be mainstream. ffmpeg only started supporting AV1 codec from version 4.0 and more decoder supports are being added as and when they come in newer versions.

So, in order to answer your question, you just need to update your ffmpeg to the latest version and it should solve the issue. Or you can download a video with a lower decoder level requirement and it will suffice. The added information is for reference so that someone who stumbles upon the question can better understand why the issue has happened and I hope it will help troubleshoot similar issues in the future.

You have three sets of double quotes nested inside each other. They are causing havoc with the bash parsing. If you want the quotes inside transported to the far end of the SSH tunnel you need to escape them with backslashes...

ssh is probably only seeing the content inside the first set of quotes:

The problem is here ytFiles.get(itag).

In the source code of SparseArray: get() will return null

You forgot to add the : at the end of the for loop:

Since results is a local variable of List<> type, I don't believe you need to await the last line. It might just work with:

You are actually not using the types properly, for the ClientSession issue, this is because you are not passing dbSession as a {session: dbSession}

so the solution for that is

Try this by string.split(separator, maxsplit)

Resize (scaling) and rotation of the video requires using filters. Filters require re-encoding.
