ffmpeg 2.2.2 However as per Audacity Manual tried to link library.But not at all recognizing

Here is the FAQ http://manual.audacityteam.org/o/man/faq_installation_and_plug_ins.html#ffdown. Follow those steps. There is no need to link anything. Just install per the instructions should work.

If it doesn’t work for you, please give the exact place in the steps where it fails, tell us of any error messages you receive, and post the log from Help > Show Log… . Please see here for how to attach files: https://forum.audacityteam.org/t/how-to-attach-files-to-forum-posts/24026/1

I have imported 2 multichannel audios, wav format 5.1 ie: 6+6 - 12 tracks.Both of varying length. I want to apply 15 seconds silence at the ens of both the audios & export.How to align these tracks ends and simultaneously apply silence & then export as I imported as 2 new modified multichannel 5.1 files to play.

You can’t align starts and ends of tracks of different lengths without changing the tempo of one set of tracks, or without cutting pieces out of one set or inserting/repeating in the other set.

Do you mean you only want to align the ends?

Please find below FFMPEG Library loading error. Lame loaded.Hence I have cut that portion. FFMPEG tried to load twice or thrice. So log might repeat

Look in *C:\Program Files*
Is there a folder called FFmpeg for Audacity
If not (and I suspect not), uninstall your current version of FFmpeg and follow the first set of instructions here:
http://manual.audacityteam.org/o/man/faq_installation_and_plug_ins.html#winff

The text has highlighting and links but looks similar to this:

Windows

Go to the external download page
Left-click this link, do not right-click.
Directly underneath “For FFmpeg/LAME on Windows click below:”, left-click the link ffmpeg-win-2.2.2.exe and save the file anywhere on your computer.
Double-click ffmpeg-win-2.2.2.exe to launch the installer (you can safely ignore any warnings that the “publisher could not be verified”).
Read the License and click Next, Next and Install to install the required files to C:\Program Files\FFmpeg for Audacity (or C:\Program Files (x86)\FFmpeg for Audacity on a 64-bit version of Windows).

nivedhya · March 2, 2016, 5:31pm

This is the first thing I verified & the folder is there. More than 5 to 6 times I have uninstalled both FFMPEG & Audacity but of no use.

Gale Andrews:

Assuming you want to align the track ends without adding silence at the ends as the means of align, click in the first shorter track, press End on your keyboard, hold SHIFT and click in the Track Control Panels of the other tracks you want to align, then Tracks > Align Tracks > End to Selection End.

Then click in the topmost track, K, hold SHIFT and DOWN arrow to extend the cursor through to the bottom track, then Generate > Silence… .

Open Edit > Preferences…, Import / Export section and enable “Use Custom Mix”.

Hold SHIFT and click in the Track Control Panels of the tracks you want to export as the first file, File > Export Selected Audio… . Repeat for the second file.

I don’t see the point of the end align though, unless you want the file for those tracks to now have silence at the start. If you want that, then before export you will have to generate silence in the white space to left of the audio in those tracks.

Gale

As per above I could be able to align track ends, generate silence in one shot for all files. So far so good. But problem is

when exporting to save as separate files, I have to give channel mapping since it shows 12 channels (adding together 6 tracks of each song) & I have to save one by one each song with 6 channels.
Exported both songs to maximum song length. ie: either adding additional silence at beginning or if I realign the tracks to start additional silence at end.
ie: if one song is 3 minutes & 38 seconds with 10 seconds of generated silence it is exported ok.
if next song is 2 minutes & 38 seconds with 10 seconds of generated silence it is also exported to 3 minutes & 38 seconds with 1 minute of extra silence at
the front. Suppose if I align this smaller song to start of the track this 1 minute silence is added to end apart from my 10 seconds of generated one.

Suppose if I add silence for 15 songs imagine my fate for channel mapping & export as individual songs.

steve · March 2, 2016, 5:54pm

What’s in that folder? (You can post a screenshot to save typing)

Gale_Andrews · March 2, 2016, 5:55pm

But we do see at one point in the log:

21:45:50: User-specified path = ‘C:\Program Files\FFmpeg for Audacity\avformat-55.dll’
21:45:50: User-specified FFmpeg file exists. Success.

The most logical explanation is that the installation has become corrupted.

Exit Audacity.

If it exists, delete the folder 'C:\Program Files\FFmpeg for Audacity".

If you don’t want it, delete the folder “C:\Program Files\ffmpeg-2.2.2-win32-shared”.

If you added "C:\Program Files\ffmpeg-2.2.2-win32-shared\bin" to PATH in the Windows environment settings, remove "C:\Program Files\ffmpeg-2.2.2-win32-shared\bin" from PATH. That PATH entry should not matter in 2.1.2 even if FFmpeg in “C:\Program Files\ffmpeg-2.2.2-win32-shared” is corrupt, but I suggest deleting that folder and any PATH entry anyway.

Open Windows Explorer and type the following in the address bar:

%APPDATA%\Audacity

Press ENTER on your keyboard. In the Audacity folder that appears, delete the file “audacity.cfg”.

Now install http://lame3.buanzo.com.ar/ffmpeg-win-2.2.2.exe to “C:\Program Files\FFmpeg for Audacity”.

Now launch Audacity. FFmpeg should have been detected and you should see F,C,U numbers for it in Libraries Preferences.

I thought you wanted to export two 6-channel files, one file containing the longer tracks and one file containing the tracks that were shorter.

If you see 12 channels in the Advanced Mixing Options then either you have not SHIFT-clicked to select only the tracks you want to export, or you have not chosen File > Export Selected Audio… .

If that does not help please describe as clearly as possible exactly what files you want to export.

Gale

Gale_Andrews · March 2, 2016, 6:13pm

Please describe exactly what you want to happen when you export the track that starts at 1 minute, lasts for 2 minutes 38 seconds and then has 10 seconds of closing silence.

Is that track supposed to be one track in a 6-channel file? If so are the other tracks in that file also starting at 1 minute, lasting 2 minutes 38 seconds with 10 seconds of closing silence?

For this batch editing as trial case, I have imported 2 nos. of wave format 5.1 channel configuration songs of different lengths. One longer & one shorter. So totally 12 tracks got loaded for editing. After editing

I have selected 5.1(6 ) tracks for export (ie: one song of shorter length) to become a single surround wave file. This song original length is 2 min 28 seconds. Added 10 seconds of silence. So it has become 2 min & 38 seconds length now.This should be my exported output song length. But even if I select this 6 tracks alone & export, it is exported to 3 min & 38 seconds long ie; previous song length. (with 1 minute additional silence(which I have not added) either at the start ie: original song starts after one minute silence, plays for 2 min.28 sec and 10 more seconds silence at end which I added or if I move all these 6 tracks to start at zero this 1 minute silence is added at end. ie song starts immediately, plays for 2 min 28 sec+10 seconds of added silence & 1 more minute of silence which I have not added)

Align the ends of those tracks to the start of the silence that you added.

The only reason that silence will be added for the first minute is either that you actually have a flat line (which is still exportable audio) for the first minute. Or you have some audio that you can’t see at your current zoom level at the start of the track.

Click at 1 minute (the start of the audio you want). Hold SHIFT and press HOME. Hold SHIFT and click in the Track Control Panels of the other tracks you want to export for this file. CTRL + ALT + K to Split Delete. You will now see just empty space for the first minute. Then SHIFT + END.

Now go ahead and File > Export Selected Audio… .

This bug http://bugzilla.audacityteam.org/show_bug.cgi?id=866 is probably relevant. The fact that Audacity is also checking PATH seems to imply that the installed FFmpeg in Program Files is not invalid, but “not found”. So it’s the right version of FFmpeg but perhaps there are shared files missing or something like that.

Thank you so much. One of my issue adding silence & exporting tracks resolved & sucessful.

But as far FFMPEG all whatever you have mentioned I tried. Removing from Path, Removing from audacity configuration file everything suggested in this & every forum. Audacity is so Audacious in accepting FFMPEG library while lame is getting accepted lamely (so easily) when I’m loading both simultaneously in same way.

Almost fed up due to more than 10 times uninstall & install business.

Before doing all this deleted/uninstalled all ffmpeg seen anywhere on my lap.

Also ffmpeg folder content neither my screen shot gets copied nor getting attached as.docx.Get me a way to load it for you to see

Gale_Andrews · March 3, 2016, 7:05pm

I don’t think you are installing FFmpeg the same way as LAME. Nowhere do our instructions say to install a second FFmpeg and add it to PATH.

Please follow https://forum.audacityteam.org/t/windows-7-audacity-2-1-2/41682/12 to the letter. When you have done that, launch Audacity and show us that log.

Also note that you don’t need to load FFmpeg dynamically using DLL files through Libraries Preferences. You can choose (external program) when you export then type a command to use any ffmpeg.exe you like. There should be no issues detecting FFmpeg with that method.

If you attach a normal PNG or JPG image without putting it inside a proprietary document format, then you can upload it using these steps: https://forum.audacityteam.org/t/how-to-attach-files-to-forum-posts/24026/1

For example, press the Windows button on your keyboard, type “Snip” (without quotes) then ENTER to open Snipping Tool. Save your image with that tool.

I completely uninstalled Audacity,FFmpeg,Lame all & removed residual files also through powerful scan & removed programes suspected to have link with ffmpeg like eac3to. Searched for any folder or files named ffmpeg after uninstall.Ensured nothing left over. Reloaded Audacity, followed in letter & spirit including left click everything as per Audacity manual & your reply, ensured path is empty & loaded both ffmpeg & lame exe files for windows & run but below is the log.

Checked the log myself. Suspected it is trying to check path.Hence after adding the location to path again relaunched Audacity. No use.More than 15 times till date ,all exercises I have done. I’m not so what to say … not to understand manuals & procedures.Please let me answer while lame is loaded why not ffmpeg.As per manual I follow same process.It is only an execution file normally gets loaded in c drive Program files location & run.

Anyhow I have given the log after fed up.If possible give some alternate solution than to follow manual

PATH = 'C:\ProgramData\Oracle\Java\javapath;C:\Windows\system32;C:\Windows;C:\Windows\System32\Wbem;C:\Windows\System32\WindowsPowerShell\v1.0\;C:\Program Files\Broadcom\Broadcom 802.11 Network Adapter\Driver;C:\Program Files\Intel\WiFi\bin\;C:\Program Files\Common Files\Intel\WirelessCommon\;C:\Programe Files\FFmpeg for Audacity\'

Notice the final entry;

C:\Programe Files\FFmpeg for Audacity\

Are you using an English version of Windows? Where did the “e” at the end of “Programe” come from?

Gale_Andrews · March 4, 2016, 3:09pm

If you want to use the export commands that have “(FFmpeg)” after them, that requires loading DLL files that have names starting with “av”. Therefore if conflicting DLL files are the problem, you should search for av* and not ffmpeg.

That is not correct. The normal FFmpeg exports require loading of DLL files, as above.

I already did. As I said, export using (external program) and type out the export command you need, starting with the path to FFmpeg. This does use ffmpeg.exe. See http://manual.audacityteam.org/o/man/exporting_to_an_external_program.html#ffmpeg for some examples. Please read all that page to understand how command-line export works.

Exactly what do you want to export with FFmpeg? Six-channel AAC files?

As Steve said, you have an item in your PATH "C:\Programe Files\FFmpeg for Audacity". I don’t think that should be the problem, but obviously that is a typo and redundant. I recommend you remove that item from PATH.

Gale_Andrews · March 4, 2016, 3:17pm

Your screenshot looks OK. That location must be “C:\Program Files\FFmpeg for Audacity” (the normal location you install applications to), not “Programe Files”.

Two other things you could try.

You could try exiting Audacity, uninstall FFmpeg, delete audacity.cfg then install FFmpeg to the folder where you have Audacity installed. I don’t see why that should make any difference, but it might help.

The only other thing you could try is to install the x86 version of Dependency Walker. This might let us see if there is something missing on your Windows system that prevents the DLL’s being loaded. Drag the installed “avformat-55.dll” into Dependency Walker and File > Save the DWI file. Repeat for “avcodec-55.dll” and “avutil-52.dll” and save those two DWI files. Zip up the three DWI files and post the zip file on Dropbox or your favourite storage service.

The first suggestion of deleting Audacity cfg file,uninstaling ffmpeg, reinstalling & relaunching Audacity did not work.In Path also I changed the spell mistake.Still no result.

dll files while loading into Depends showed some error or warning message. As you said I have converted those as zip files & shared vide below link.Try to look into it & give me a solution. I hope this study & solution will put a full stop for all issues.
