I downloaded a video with a webm extension. The video plays; but there's no sound.
I then downloaded the audio, weba extension. It also plays; but I haven't succeeded in
marrying the the video and audio.
Then I read that I needed the audio codecs (opencodecs_0.85.17777.exe). It didn't help with the sound.
Any suggestions are appreciated.

Youtube.

YT has "combined" video streams - video+audio.
YT has "separate" video streams - video separate from audio.

If you download the latter you get either video or audio - depending on which you actually download.
If you want both, you need to download both & MUX them together.
(You want to make sure you download compatible audio & video bits. IOW, webm audio won't work with the video in a .mp4 container.)


FlashGot is well dated at this point - in regards to YT.
(YT fairly regularly makes changes to its end that software makers have to adapt to. FlashGot has not been updated in ages, with no update in sight.)

That said, FlashGot works just fine most everywhere else.



You can use FFmpeg to MUX the audio & video easily enough.
I select the two files (1 audio, 1 video) from my file manager, & then SendTo -> MUX.BAT.

MUX.BAT
Code: Select all
@ECHO OFF

ECHO  MUX a (generally) Youtube DASH Video (only) + Audio (only) MP4/WEBM
ECHO  therube 01/13/2015
ECHO.
ECHO  %1

Hi therube,
I have been able to mux the audio and video using Format Factory; by converting them to avi and mp3 and joining those; but it was a tedious process. Is there an easier way to mux them, or maybe a better down loader?

by converting them to avi and mp3

MUX involves no transcoding, no quality loss, takes a few seconds, literally.


Long ago, I used (looked at, more appropriately said), "Keep Video Joiner".
(Since then, I've used my MUX batch file.)

Source, seems to have gone "pay-ish", https://keepvid.com/.
The file is still there, but not "shown", 11 MB & includes an ancient version of FFmpeg, http://keepvid.com/downloads/KeepVid%20 ... 0v0.15.zip.

Alternatively, the .exe only, 9 KB zip'd, is here, https://drive.google.com/file/d/1a6oiHR ... sp=sharing.
You'll need your own version of FFmpeg (but as what would otherwise come with it is old...).

My readme:
Code: Select all
KeepVid Video Joiner.zip   aka   VidJoin.exe
uses FFmpeg (ffmpeg.exe), which it (normally)
includes in its archive, but it works just as
well with any existing version, so long as it
can find it, either in its program directory,
or somewhere in your PATH, so ... i've nix'ed
it from here, leaving just their (tiny) GUI
front-end instead :-).



(Maybe even FormatFactory can do the same without transcoding?)

If you don't care about resulting container, then you could use mkvtoolnix

Also you can use mpc hc for playback, it will mux those streams on the fly

Hi the rube,
I think I'm using the term 'mux' wrongly. Would you mind setting me straight on what it actually is?
The definitions I've read, used terms I didn't really understand.
Thanks,
.... john

With some downloaders I have noticed that if you try to get a high resolution of the clip, 1080 or higher, there are problems such as separate streams, but the same clip in 720 or maybe lower is automatically a single file.
As for mux or combining files, I agree, good software can usually combine an audio and video file without re-encoding or transcoding either, and it should only take a few seconds. Re-encoding could lose quality and take a very long time. To play back the combined file, you still may need the right codecs though. Many players use external codecs, but I believe VLC player comes with all the stuff it uses built in.
I've heard this is good for downloading youtube: https://rg3.github.io/youtube-dl/ It is not part of any browser, it is just a command line utility. If you like, you can get a GUI front end for it.

Hey -Px- that worked really well.
How do I save the entire video, in one file, so that I can show it to others?

Well, as it was said before, you need to mux two files into one. I've made a quick search, and it looks like VP8/9 is not supported in mp4 container, so your only choice is mkvtoolnix. Just put two files into Source section, and it should make them a single one with .mkv extension
