Provide a description that is worded well enough to be understood

Right now when I use -F to find the available formats for a Nebula video, yt-dlp offers 360p, 540p, 720p in AVC encoding (H264), and 1080p, 1440p and 2160p in HVC encoding:

ID            EXT RESOLUTION FPS │   FILESIZE    TBR PROTO │ VCODEC           VBR ACODEC  
─────────────────────────────────────────────────────────────────────────────────────────────

2283          mp4 960x540     60 │ ~505.69MiB  2284k m3u8  │ avc1.42C028    2284k video only
4672          mp4 1280x720    60 │ ~  1.01GiB  4672k m3u8  │ avc1.640029    4672k video only
5730          mp4 1920x1080   60 │ ~  1.24GiB  5731k m3u8  │ hvc1.2.4.L123  5731k video only
8024          mp4 2560x1440   60 │ ~  1.74GiB  8024k m3u8  │ hvc1.2.4.L150  8024k video only
16449         mp4 3840x2160   60 │ ~  3.56GiB 16450k m3u8  │ hvc1.2.4.L153 16450k video only

These are the exact same formats returned by the Nebula API at https://content.api.nebula.app/video_episodes/video_episode:2662249c-5844-4f2e-9caa-e74405e9d840/manifest.m3u8?token=token_censored

However when I watch a Nebula Video in Browser, it uses a slighly different URL - it appends the parameters &app_version=23.6.0&platform=web to the m3u8 URL.

Adding &platform=web to the M3U8 URL makes it return the higher-resolution videos (1080p and 1440p) in AVC / H264 as well:

$ yt-dlp -F "https://content.api.nebula.app/video_episodes/video_episode:2662249c-5844-4f2e-9caa-e74405e9d840/manifest.m3u8?token=token_censored&platform=web"

7487          mp4 1920x1080   60 │ ~  3.02GiB  7488k m3u8  │ avc1.64002A    7488k video only
11877         mp4 2560x1440   60 │ ~  4.79GiB 11878k m3u8  │ avc1.640034   11878k video only

Can yt-dlp be made to automatically query the video twice when using the Nebula extractor, once without platform=web and once with platform=web? Or is there a seperate parameter for the Nebula extractor to trigger this "web" parameter?

I like to download videos in both H264 and H265 so I always have to get the M3U link from a browser to be able to set the parameters. I took a look at the Readme but it doesn't look like the Nebula extractor supports extractor arguments like YouTube does.

Basically, I'm looking for a command that results in this output (and/or lets me download all these formats):

(so I can download one of the 2160p formats, and the 1440p format both in H264 and H265).

Provide verbose output that clearly demonstrates the problem

• Run your yt-dlp command with -vU flag added (yt-dlp -vU <your command line>)
• If using API, add 'verbose': True to YoutubeDL params instead
• Copy the WHOLE output (starting with [debug] Command-line config) and insert it below

There are multiple nebula issues open for which we basically know the fix but have no account to test with. If you can share account, I can have a look.

[Leseratte10]

Yeah, if necessary I can do that. Should I send mail and password to the email on your Github profile?

[pukkandan]

Yes pls
