Script Error: Exception: (_tp_dict_get) KeyError: splitext

[Grim Reaper]

Hi,

I need assistance to get a batch conversion script running. I have no Python programming knowledge.

I got a batch processing python script from a 2021 Avidemux Forum post (posted over 120 days ago) and modified it slightly to batch convert the audio in some video files from MKV to AAC(lav). Apparently, the script ran fine for the person who got assistance writing the script.

I am using AVIDEMUX 2.7.7 on a MacMini running Mojave (I will not update to a newer MacOS version because I need to run 32 bit apps)

The script runs and enables selection of the input file type and the input and output folders, loads the first video in and changes the default audio from copy to AAC(lav) but the script run dies with the following error:

TinyPy:Exception

I am using AVIDEMUX 2.7.7 on a MacMini running Mojave

If this is a nightly from here, it is too old to have the splitext method which was added to Avidemux on Feb. 7 2021. You might try whether it works with the line containing

Code Select Expand

filename = (splitext(filein))[0]
deleted (you will get a double file extension then).

In general, only the latest release i.e. 2.8.0 is supported. It might be possible to build it from source on Mojave, but I have no means to verify. In case of problems, you would be entirely on your own.

[Grim Reaper]

The person who posted the original python script that was modified to work successfully used it on a Mac running Mojave and AVIDEMUX 2.7.7. I don't know why splitext isn't compatible if it ran ok for him.

I took out the line containing splitext, the following error resulted:

TinyPy:Exception

Exception: (tp_add) TypeError: ?

Oops, I'm sorry, filename needs to be set, so please replace

Code Select Expand

    filename = (splitext(filein))[0]
    filename += ".mkv"
    filename = basename(filename)
    return adm.save(out + sep + filename)
with

Code Select Expand

    filename = basename(filein)
    filename += ".mkv"
    return adm.save(out + sep + filename)

The person who posted the original python script that was modified to work successfully used it on a Mac running Mojave and AVIDEMUX 2.7.7

"2.7.7" means a build created after the release of 2.7.6 and including the release of 2.7.7 instantly superseded by 2.7.8, so unless the "About" dialog says "Release" and doesn't contain a git commit hash, it is a nightly from that broad time range. If the obsolete build you use has been compiled from source after February 7 2021, it has support for splitext method. Else it hasn't.

[Grim Reaper]

Thanks for your assistance.

The script now works, mostly.

1) It doesn't ignore files that do not have the selected file extension, it puts up error warnings, one was for a text file it tried to process in the selected directory , which prevents the script from continuing until the error warnings are eliminated then the batch processing continues on to the next file in the directory. Is there a way to prevent that?

2) Because the original file name isn't parsed by splitext, the script appends ".mkv" to the full filename including the extension of the original file. Is there a way to delete the original file extension from the processed file name?

3) I would like to compile the most recent version of Avidemux to run on Mojave. I have Brew and Xcode installed on my MacMini running Mojave. Where is the most recent Avidemux code source and what is the method for compiling it?

[eumagga0x2a]

1) It doesn't ignore files that do not have the selected file extension

I cannot reproduce this issue with current Avidemux (e.g. files with names ending in .txt as well as files completely without an extension get correctly ignored), so this might be a bug fixed along the way. I guess we should not waste time on catering to limitations of obsolete versions, there are dozens of other substantial bugs fixed in the meantime.

3) I would like to compile the most recent version of Avidemux to run on Mojave. I have Brew and Xcode installed on my MacMini running Mojave. Where is the most recent Avidemux code source and what is the method for compiling it?

If you can get Qt (preferably Qt6) installed in Homebrew

Code Select Expand

brew install qt
then we should be fine. Build with Qt5 (qt@5 in Homebrew) was broken last time I checked ~ a month ago.

Code Select Expand

brew install cmake nasm yasm xvid x264 x265 libvpx aom opus fdk-aac lame libass mp4v2 a52dec
would install remaining build dependencies (strictly speaking, build deps are cmake, nasm, yasm and qt, but the remaining packages are desirable for a fully-featured application). If Xcode command-line tools (which include the actual compiler) are not yet installed, brew should prompt for their installation.

Code Select Expand

git clone https://github.com/mean00/avidemux2.git && cd avidemux2 && git submodule update --init --recursive
clones the Avidemux source and the translations to subdirectory avidemux2 of the current directory.

Code Select Expand

export MACOSX_DEPLOYMENT_TARGET=10.14
bash bootStrapOsx_Catalina.bash --enable-qt6
in avidemux2 directory would try to build Avidemux, packaged as a disk image, for Mojave.

[Grim Reaper]

QT@6 is not supported by Mojave, Qt@5 is.

This doesn't work:

Admins-Mac-mini:~ admin1$ export MACOSX_DEPLOYMENT_TARGET=10.14
Admins-Mac-mini:~ admin1$ bash bootStrapOsx_Catalina.bash --enable-qt6
bash: bootStrapOsx_Catalina.bash: No such file or directory
Admins-Mac-mini:~ admin1$

Looks Like QT6 Installed:

Then leave --enable-qt6 out and keep fingers crossed that the bug presumably Homebrew is responsible for has been fixed.

[eumagga0x2a]

The build might still fail in the Qt-related part as I didn't care of Qt5 since it got broken a few months ago. I'll try to find a way to get it build then. It might take time though.

I assumed that pkg-config will be pulled in automatically, but this seems to be wrong. Please install pkg-config manually

brew install pkg-config
and Avidemux should build fine with Qt5. I've just did it successfully on Monterey, albeit with Qt6 uninstalled, but coexistence of Qt6 and Qt5 is luckily not an issue on Mojave.

[Grim Reaper]

I reinstalled Homebrew, etc. then tried to build the .dmg but it failed with the following (I think it can't find qmake):

+ echo 'Error: No matching qmake executable found, aborting.'
Error: No matching qmake executable found, aborting.

I will reinstall with this: brew reinstall cmake
then try again.

[eumagga0x2a]

I reinstalled Homebrew

Why, just why? The only apparently missing thing was pkg-config.

+ echo 'Error: No matching qmake executable found, aborting.'

Again, why?
