That's the plan, in facts.
(On a side note, FlashGot is not going to download the highest resolutions as muxed streams not by bad will, but because Youtube doesn't make them available anymore: they're demuxed or nothing).


Cool. If FlashGot will do all the remuxing work, I'm aboard and patient.

I followed user's instructions to make them appear as resolution (e.g. 240p) instead of label (small), this applies to audio streams as well.

Set flashgot.media.YouTube.remap_stream_quality=true to use the "XXXp" notation. The problem is, since I used the same notation for audio streams ("large" for 250k, etc.), they will be remapped as well, e.g. "large" -> "480p", which makes no sense.
Set media.YouTube.remap_stream_type=true to use shortened type notation for video streams: "mp4" instead of "video/mp4", etc."

Fixed type remapping bug and added quality remapping for audio streams: "large" <-> "256k" (250k mp4, 209k webm), "medium" <-> "128k" (125k mp4, 138k webm), "small" <-> "48k" (48k mp4).


Well yes, as you can see, there's supposed to be "large" audio/mp4 for "large" video/mp4.

Questions 5, 8 (and also 2, 6).

There's no need to be a "logical" asshole here, user.

I'm just saying there's no longer matching mp4 480p audio stream. The fact remains it was there before, YT must have hidden it or something.

I'd also like to toss something else into the mix.
It's a bit confusing that in the DASH container, the video only streams are called video, but the muxed versions are also called video.

Jdownloader (which has much more problems right now with youtube than Flashgot does) lists/listed muxed streams in a notation like this:
NameOfVideo(360p_DASH_H.264-AAC).mp4
NameOfVideo(360p_VP8-Vorbis).webm

Audio only were listed as such.
FlashGot could list unmuxed streams as:
NameOfVideo(480p_DASH_H.264).mp4
NameOfVideo(480p_DASH_AAC).aac

That way you could differentiate. Unless of course unmuxed streams are going to be removed once this whole issue is cleared up, in which case it doesn't really matter.

That totally works, thanks! It took me a minute to figure it out, but then after that it was smooth sailing! :D

Has anyone else noticed any instances in the DASH container of lergest audio being missing even though the video is there?

Is there anything that says if you have a Large video, there need be a corresponding Large audio?

Or could it be that there exists a Large video but only Medium or Small audio?

@therube - Not necessarily but the higher quality videos usually include improved quality audio. Without being tagged as the audio that comes with highest resolution stream, you'd just be guessing.

@CuF

Exactly. You can tell by their filesize as well. The corresponding audio are what you'll get if the streams aren't demuxed in the first place.

It's not that hard to understand. Check my previous post. Why settle for less when there are superior ones (supposedly) available?

48k dash audio streams have disappeared, are they gone or not being detected?

Ugh, tried working with ffmpeg today, it's pretty annoying. Is there something with a GUI that can do this?

Eh, real quick...

Video To Video, Tools, Mux, makes it easy.
(Link at videohelp.com/tools, I think it is.)
Select the video, select the audio, & tell it to go.
Done in a few seconds.

BUT, it needs an update to its decoders (lav I think it was) to properly recognize DASH.

(more when I get time)

What program are you referring to?

I'm more surprised that apparently MKVToolNix doesn't support DASH and it doesn't appear to have been requested.
Tried YAMB and that doesn't work either.

Video to Video Converter.
(It will need updates to some of its components that it uses. Don't recall if it was LAV or FFmpeg? Thinking FFmpeg, shared, not static version...?)

(more later, perhaps, or this evening, if I have electic...)
