All YouTube Downloads Failing as "Empty"

retroblasting

Using latest version of Streamfab - YouTube downloads on all clips failing after analysis as “the downloaded file is empty.”

Was working fine 48 hours ago. I assume YouTube has pulled some kind of stunt.

Try 7007 as YouTube works.

Funny thing… did not see any verbage about updating the YT download engine in the release notes.
Wonder how many other things were secretly updated.

7007 is using 2025-12-08. (latest release version of yt-dlp, but many nightly’s since. (2026.01.06)
7006,7005 has 2025-12-08 too.

I get why some don’t want to use yt-dlp as it’s accessed via command line. And I now use yt-dlp (nightly) always.
If not, then I highly recommend Stacher7, an amazing GUI wrapped around yt-dlp (nightly’s) and deno.
(YES for FREE)
As Stacher7 is run each day it keeps updated to the latest nightly of yt-dlp and checks for deno.

Jdownloader2 has let me down. Now I have not checked in the last month, but after asking the developer of jdownloader2 about YT videos srt, and being told it can not download them, I lost interest.
I hope that gets fixed or is fixed.

Even TubeDigger can get srt’s.

As for me, YT still works in SF.
The browser in SF is older than me. Keep an eye out on or after Jan 20th.
SF browser is still v138, and the latest is v144, and SF fakes the browser user agent

Back in the day I didn’t have issue with using CLI, nowadays it’s more of a PITA.
I still use Open Video Downloader mostly. Only gripe about it is it doesn’t use cover.jpg, but that’s ever so minor.

As I’ve previously written, SF needs to do away with YoutubeToMP3Process.exe, and they need to allow the user to use the latest yt-dlp. Too many programs that do their work in the background of StreamFab are just old and out-of-date.
These are the files that I update to their newest version with each and every update of StreamFab. Most can be gotten at their GitHub sites.

ccextractor.exe
dash-mpd-cli.exe
libcurl.dll
MediaInfo.dll
mkvmerge.exe
mp4box.exe
shaka-packager.exe
ffmpeg.exe (BtbN Nightly Master build)
aria2c.exe
AtomicParsley.exe
deno.exe

Those who it does not work never provide a log.
YT is working in 7007, locked

Logs and step by step how to repeat issue is needed.

Found reasons for the downloaded file is empty.
New topic made. As always, include logs if more issues.
