PlaylistItems seems to be limited to 20 000 entires for uploads playlist. Is there any workaround?

Question

It seems that somewhat recently uploads playlists were limited to 20 000 entries. Is there a way to get list of all videos uploaded by a channel?

For example channel UCFL

You may try using repeatedly the Search.list API endpoint queried with the following parameters:

• channelId=UCFL1sCAksD6_7JIZwwHcwjQ,
• type=video,
• order=date,
• publishedBefore=...,
• maxResults=50,

where publishedBefore is computed appropriately.

The initial publishedBefore is set to 1 second before the value of the publishedAt property of the (chronologically) last video you have obtained from PlaylistItems.list endpoint invoked with playlistId=UUFL1sCAksD6_7JIZwwHcwjQ.

Successive values of publishedBefore will be set, similarly, to 1 second before the value of the publishedAt property of the (chronologically) last video of the previous call to Search.list endpoint.

One more remark: do note that -- even if the API will allow you to go beyond the 20000 limit using the algorithm above (I don't know if it will; you have to test that yourself) -- the cost of this procedure is quite high: each Search.list endpoint call has a quota cost of 100 units (expensive indeed).
