Description

When I try to download a video from the CBC News site (NOT CBC Gem), it now gives me a 404 error and says the XML file cannot be found. It was working until recently and I have reverted to using the m3u8 method unless and until this issue is resolved.

This looks like, and is, the problem reported in yt-dlp/yt-dlp#9534.

#30839 "if you were actually using yt-dlp ..."

However yt-dl also has the problem and we should be able to use the same solution. After revising a WIP PR from several years ago that was never merged to include some of the changes from the yt-dlp PR:

Rather than passing the ID from the URL directly to the video host, we have to extract a media ID from the hydration JSON in the video page.

[trainman261]

Yes, this is the exact same problem. I'll be updating the PR at yt-dlp in a bit, the same changes should be usable here as well.

[dirkf]

I noticed that the video host URLs used by the site contain the query parameter formats=M3U,MPEG4,MP3 (used in the above test patch, too) rather than the olde worlde formats=MPEG4,FLV,MP3 in the extractor(s).

Maybe this is ignored, or maybe it'll start to cause a problem later if ThePlatform withdraws some level of FLV support.

[trainman261]

IIRC, formats=M3U,MPEG4,MP3 preferentially downloads the m3u manifest if available (which contains the information for streaming the individual chunks), whereas formats=MPEG4,FLV,MP3 preferentially downloads an MP4 file as a whole. For streaming, downloading it in chunks makes more sense - plus it offers the benefit that most of the M3U files have multiple streams specified for different bandwidths, allowing for the media player to chose the appropriate stream based on the current resolution and available bandwidth. For downloading, however, it makes more sense to download the MP4 as a whole, since that generally has better performance on in this case, since it avoids all the overhead of downloading often 100+ chunks (with associated I/O) and assembling them all back together afterwards.
