Quality
Now that Discovery+ has switched to DASH videos, can we please get a selection screen like Amazon and others?
Downloading an almost 6GB file for an episode of 90 Day Fiance is just a waste. There is no fast moving action or anything that justifies such a high bitrate so please do allow us to choose a lower quality. They do have several qualities available:
The subtitles have never worked with Discovery+. I had to resort to downloading videos with another tool and then use yet another tool to extract the subtitles.
This method no longer works now that they are using DASH but i figured out another way for DASH videos.
Please pass on to the developers:
Basically, the subtitles are DASH subtitles that have their own "empty" video track. Using the program that is behind your Youtube downloader, with the following command, it downloads 2 .mp4 files. 1 is the subtitles and the other is the actual show.
As long as the video resides on Akamai and not Google's CDN, it will download both files. They are working on a fix for the Google CDNs.
The video that is "filename".en.mp4 is the one that has the subtitles. They are in WebVTT format and need to be extracted and converted to SRT by doing the following:
In case i am not explaining well, here is the batch file i use to convert a single subtitle. %1 is used to pass the filename so nx1 is with the extension and n1 is without:
It would be extremely appreciated if you guys can fix a longstanding problem that will make many people (i think) happy.
You have the solution so there is noting to figure out except incorporate the Bento4 libraries and looking at the C# source for MP4SubtitleParser.
Thank you!

Code:
ThatYoutubeProgramSomeOfUsUse.exe -U -i --write-sub --add-metadata --extractor-retries 10 -o "%%(series)s.%%(season_number)sx%%(episode_number)02d.%%(title)s.%%(height)sp WEB-DL.%%(ext)s" --downloader aria2c --convert-subs=srt --embed-subs --all-subs --ignore-config --hls-prefer-native --no-geo-bypass --cookies-from-browser chrome "URL_OF_EPISODE"
The video that is "filename".en.mp4 is the one that has the subtitles. They are in WebVTT format and need to be extracted and converted to SRT by doing the following:
- Use mp4split from Bento4 to split the .mp4. It will create one file called init.mp4 and several files called segment segment-1.0001.m4s, segment-1.0002.m4s, segment-1.0003.m4s, etc..
- Use Mp4SubtitleParser on the folder containing the init.mp4 and *.m4s files to get a filename.vtt file.
- Use FFmpeg to convert the .vtt to .srt
In case i am not explaining well, here is the batch file i use to convert a single subtitle. %1 is used to pass the filename so nx1 is with the extension and n1 is without:
Code:
@ Echo off REM ************************************************ REM Extract CC from DASH MP4 (MP4SubtitlesExtractor) REM ************************************************ setlocal ENABLEDELAYEDEXPANSION md Subs copy "%~nx1" Subs cd Subs mp4split "%~nx1" cd .. mp4subs Subs *.m4s "%~n1" ffmpeg -i "%~n1.vtt" -c:s subrip "%~n1.srt" pause
