Some command line parameters not working (Avidemux 2.7)

[tischuer]

I'm using Avidemux 2.7.0 Final (under Ubuntu 17.10 and openSUSE Leap 42.3).

This version doesn't seem to recognise the parameters --audio-codec and --nogui. Is this a know problem?

And is there a up-to-date list of the codec names for --video-codec and --audio-codec? Even "--help" seems to list some codecs that aren't supported by Avidemux 2.7?

btw: I've tried the AppImage and the versions from the Packageman, GetDeb and PPA repositories. All these versions had/have the same behaviours.

--nogui is normally for the Graphic User Interface, when you use avidemux3_qt5 instead of avidemux3_cli in the script. Testing or you find some stuff not working from cli. Let us know what is not working. Devs could have a look at it, and perhaps have a solution for it.

With the  GUI make your wanted settings, and save the projectscript: Avidemux Menu: Files: Project Script: Save As Project: 'MyProject.py'

You can get Clues from that script 'MyProject.py' what to use in command line parameter

adm.audioCodec(0, "Opus");

If you are on 64-bit you could try this latest build: dev branch: avidemux Cli/Qt5 2.7.0 64-bit deb on ubuntu HWE 16.04.3 LTS

Hi Jan, thanks for your quick answer!

--nogui is normally for the Graphic User Interface, when you use avidemux3_qt5

That's the case: "avidemux3_qt5 --nogui ..." won't disable the GUI. Or in other words: I see the GUI even if I use "--nogui".

"--audio-codec" doesn't work at all. For example ...

avidemux3_cli --video-codec Xvid --audio-codec MP3 --load test.mp4 --save out.avi --quit

... won't encode the audio stream in MP3, but leaves it in AC3. I get the following error message:

audio-codec-->1
[32m [audioCodecSetByName] 15:17:51-322  Setting MP3 audio codec for track 0
[m[33m [audioCodecSetByName] 15:17:51-322  Cannot set codec for track 0

I get this error message every time, regardless which codec I use (and it doesn't matter if it's avidemux3_cli or avidemux3_qt5).

You can get Clues from that script 'MyProject.py' what to use in command line parameter ...

Ah, cool, thanks!

If you are on 64-bit you could try this latest build: dev branch: avidemux Cli/Qt5 2.7.0 64-bit deb on ubuntu HWE 16.04.3 LTS

Unfortunately I have to stick with the "official" versions.

This is not exactly intuitive, but --audio-codec expects not the strings the help suggests but the internal codec name, e.g. Lame (case insensitive) for "MP3 (lame)". I've pushed a patch to allow also menu names for --audio-codec so that

Code Select Expand

avidemux3_qt5 --load /path/to/video --audio-codec "MP3 (lame)"

should work in future builds.

To set an audio codec on command line, a video must be already loaded, i.e. the --load option with the path to a video must precede --audio-codec

--nogui just prevents some dialogs from opening. If you don't want GUI at all, use avidemux3_cli.

Can you check if saving mp3 audio is still correct?

Sorry, I don't understand your point.

[Jan Gruuthuse]

These tracks are all still MP3? Only .mkv has mp3 mentioned?

[eumagga0x2a]

"MP3" = MPEG 1 layer 3 and is mentioned in all cases.

[Jan Gruuthuse]

OK, got confused, good to know it's ok.

... --audio-codec expects not the strings the help suggests but the internal codec name, ...

Ha! Great, thanks, it's working now. Is this valid for --video-codec and --output-format too? Do they require the internal codec/muxer name?

To set an audio codec on command line, a video must be already loaded, i.e. the --load option with the path to a video must precede --audio-codec

After reading the Wiki I thought that too. So at least the examples on this page are wrong?

Ah, thanks!

Yes, they do (because only these names are guaranteed to be unique), though in case of video codec and container they mostly match what a user would expect.

Every time you see "Avidemux 2.5" in an example, just ignore the tutorial. It is almost sure the example is outdated then.
