Major Features: - HD video thumbnails (hq720.jpg) with automatic fallback to lower qualities - HD channel avatars (240x240 instead of 88x88) - YouTube 2024+ lockupViewModel support for channel playlists - youtubei/v1/browse API integration for channel playlist tabs - yt-dlp integration for multi-language audio and subtitles Bug Fixes: - Fixed undefined `abort` import in playlist.py - Fixed undefined functions in proto.py (encode_varint, bytes_to_hex, succinct_encode) - Fixed missing `traceback` import in proto_debug.py - Fixed blurry playlist thumbnails using default.jpg instead of HD versions - Fixed channel playlists page using deprecated pbj=1 format Improvements: - Automatic thumbnail fallback system (hq720 → sddefault → hqdefault → mqdefault → default) - JavaScript thumbnail_fallback() handler for 404 errors - Better thumbnail quality across all pages (watch, channel, playlist, subscriptions) - Consistent HD avatar display for all channel items - Settings system automatically adds new settings without breaking user config Files Modified: - youtube/watch.py - HD thumbnails for related videos and playlist items - youtube/channel.py - HD thumbnails for channel playlists, youtubei API integration - youtube/playlist.py - HD thumbnails, fixed abort import - youtube/util.py - HD thumbnail URLs, avatar HD upgrade, prefix_url improvements - youtube/comments.py - HD video thumbnail - youtube/subscriptions.py - HD thumbnails, fixed abort import - youtube/yt_data_extract/common.py - lockupViewModel support, extract_lockup_view_model_info() - youtube/yt_data_extract/everything_else.py - HD playlist thumbnails - youtube/proto.py - Fixed undefined function references - youtube/proto_debug.py - Added traceback import - youtube/static/js/common.js - thumbnail_fallback() handler - youtube/templates/*.html - Added onerror handlers for thumbnail fallback - youtube/version.py - Bump to v0.4.0 Technical Details: - All thumbnail URLs now use hq720.jpg (1280x720) when available - Fallback handled client-side via JavaScript onerror handler - Server-side avatar upgrade via regex in util.prefix_url() - lockupViewModel parser extracts contentType, metadata, and first_video_id - Channel playlist tabs now use youtubei/v1/browse instead of deprecated pbj=1 - Settings version system ensures backward compatibility

# Here's what I know about the secret key (starting with ASJN_i)
|
|
# *The secret key definitely contains the following information (or perhaps the information is stored at youtube's servers):
|
|
# -Video id
|
|
# -Offset
|
|
# -Sort
|
|
# *If the video id or sort in the ctoken contradicts the ASJN, the response is an error. The offset encoded outside the ASJN is ignored entirely.
|
|
# *The ASJN is base64 encoded data, indicated by the fact that the character after "ASJN_i" is one of ("0", "1", "2", "3")
|
|
# *The encoded data is not valid protobuf
|
|
# *The encoded data (after the 5 or so bytes that are always the same) is indistinguishable from random data according to a battery of randomness tests
|
|
# *The ASJN in the ctoken provided by a response changes in regular intervals of about a second or two.
|
|
# *Old ASJN's continue to work, and start at the same comment even if new comments have been posted since
|
|
# *The ASJN has no relation with any of the data in the response it came from
