Increasingly downloading videos started to fail. (Not just with JD)
Right now I can't download this with anything: **External links are only visible to Support Staff****External links are only visible to Support Staff**

I only get a "(BQ).jpg" in a "(BQ)" package. So even fetching the page title fails.

Alright, this includes a couple tries and some other videos:

27.01.17 18.33.26 <--> 27.01.17 19.46.24 jdlog://8535179150841/

This, only has the problematic video:

27.01.17 19.46.52 <--> 27.01.17 19.48.34 jdlog://3635179150841/

(But this time the title was fetched properly, also the description isn't missing anymore, only the video)

It looks like only youtube-dl can find and download the 1080p mp4/AVC stream.

It's still odd though. The other two parts are normal with all the VP9 streams available.

@avada: doesn't work for me neither, even in browser it doesnt work (vp9 only). we will check.
Do you have other links that show same issue? Please send example links to support@jdownloader.org

I encountered such before where there was no webm and MP4 failed to download. I didn't make note though.

(VP9 streams missing is nothing special in itself)

This video is not recognized by the left collector and can not be downloaded.

@cine: Thanks, we will check this asap

fixed with next update,thanks for reporting

When highest quality vp9 advanced option is enabled sometimes link grabber will fail to grab anything because youtube tends to encode the vp9 stream last.
Would be nice if there were an automatic fall back option to add the next best with a warning so it doesn't silently fail. Or simply a warning popup that the queue wasn't actually updated yet. I'd rather not leave add mp4 on and double the clutter in the link grabber queue for all the videos which do have vp9's completed.
Happens quite a bit on long video streams as they take youtube sometimes a day to encode into vp9

[Jiaz]

Could you please provide example links? maybe a logfile too, see https://support.jdownloader.org/Know...d-session-logs and post the shown logID.
In case the format is not available yet, it highly depends if youtube signals that it will be there in future. Without that information there is no real way to differ between *not available* and *maybe available in future*.
So you setup to chose vp9 only and when it is missing, nothing is shown, correct?

[travestree]

Yes, the vp9 as best option was something I had to enable under advanced features long ago I think. I only have best webm checked off.
Usually youtube transcodes the mp4 releases first, and the longer the video, the longer it takes to get the vp9 out.

currently working example
**External links are only visible to Support Staff****External links are only visible to Support Staff**

by the time you see it though, it might have a vp9
just a matter of finding a recently ended live stream.
15.02.17 17.39.33 <--> 15.02.17 17.41.14 jdlog://8240379150841/

[Jiaz]

So in case the vp9 isnt available, what should JDownloader do? It can either fail silenty (as it does right now) or we can add fallback support to next quality. You can already do that by adding mp4 to the collection settings yourself.

[travestree]

The problem is that it doesn't fail over, it adds both in all cases where vp9 also exists which leads to additional work and clutter.
A fail over only in cases where the vp9 doesn't exist would be nice, perhaps with notification?

[Jiaz]

You mean it adds VP9 and MP4 but you only want VP9. MP4 only in case VP9 fails/missing?

jdownloader dont show the video name, if i copy the link.

Another example happened today. It says "Various files" instead of "RF Personal Monitors, Gadget or Tool?":

make sure you have qualities available for it to work.

@dbkarm: Please check Settings-Plugins- search for youtube, the package-/filename patterns

It means that one could add both "best" webm and mp4 or even aac to get around the problem, but it would lead to additional entries in the queue to sort out for all the entries which do not need this.

YouTube seems to encode the VP9 for each video last, so for long streams they can not exist at all for a day, and only having vp9 webm "best" creates a silent fail condition. I guess that is the problem, the silent fail.
