Description

Add a specific message when a channel contains videos but they were all filtered. This can happen if videos are for members only.
I have removed This channel does not currently have any videos key because it can't be displayed. Videos tab is not displayed if there are no videos, see https://github.com/FreeTubeApp/FreeTube/blob/development/src/renderer/views/Channel/Channel.vue#L792

Screenshots

Testing

1. Go to https://www.youtube.com/channel/UC2EiGVmCeD79l_vZ204DUSw/videos
2. Check that the message is "This channel has videos but none could be displayed, try fetching more"
3. Click on Fetch more results
4. See more content being loaded

Slightly related, i just noticed that on YouTube, Its possible to select Public videos on the videos tab. Would it be possible to directly fetch Public videos for displaying it on the videos tab instead of fetching all and then filtering them?

Edit: What this PR is doing is already a good improvement but its also possible that there are e.g 6 pages full of member only content before public videos are getting displayed. So clicking 6 times on a fetch more button isnt a very good UX

@efb4f5ff-1298-471a-8973-3d47447115dc It can't be done directly, it requires one additional request.
It could be done in Channel.vue line 1141, when we detect that no videos were retrieved but more are available.
What do you think?

Code snippet prototype:

if (latestVideos.value.length === 0 && videosTab.has_continuation) {
  const get_public_videos = videosTab.memo.getType(YTNodes.ChipView).filter(item => item.text === "Public")[0].tap_command
  if (get_public_videos.is(YTNodes.NavigationEndpoint)) {
    const result = await get_public_videos.call(videosTab.actions, { parse: true });
    console.log('public videos', result.on_response_received_actions_memo.getType(YTNodes.LockupView))
  }
}

Lets wait for the Code Owners to chime in on it

@PikachuEXE any thoughts on #9791 (comment)

[PikachuEXE]

I think that belongs to another PR and potentially requires changes to YTJS (better not do too much "internal stuff"

[Shadorc]

It indeed could be part of a separate MR. Also, I've missed it, but it is already implemented in ytjs (it is two requests, I would have to dig deeper to only apply the second filter as we don't need the first one, if we chose this):

if (latestVideos.value.length === 0 && videosTab.has_continuation) {
  console.log('public videos', await videosTab.applyFilter('Latest', 'Public'))
}
