• Button "Clean FFMeta" does nothing after compiling with PyInstaller

  6 mai, par Leonie Holdermann

  I’m working on my first Python project and I’ve compiled it into an executable using PyInstaller with the following command :

  


  pyinstaller --onefile --noconsole app.py


  


  However, when I run the executable, the button "Clean FFMeta" which triggers the clean_ffmeta() function does nothing. Additionally, changing the language or the chapter settings under the "Options -> Chapter settings" menu doesn’t seem to affect anything either. It all works perfectly in the Python script before compilation, but once compiled into an .exe, none of these functions respond.

  


  I've reviewed the code, and the button is correctly linked to the function, but I suspect something might be going wrong during the compilation process.

  


  What I have tried :

  


  

  • Checked that all dependencies are included.

  


  • Verified that the configuration and language changes are being correctly applied before compilation.

  


  • Tried running the executable from a console to check for error messages, but there are none visible (since I used —noconsole).

  


  


  What I expect :

  


  

  • The "Clean FFMeta" button should clean the FFMeta file based on the
user settings.

  


  • Language and chapter settings should be updated and reflected in the GUI immediately.

  


  


  Code :
Below is a simplified version of my code, especially the sections related to the "Clean FFMeta" functionality and language/chapter settings.

  


  def clean_ffmeta():
if not config.get("cd_in_path"):
    show_error(texts[current_language]["error"] + " No CD_IN path configured.")
    return

chapter_path = os.path.join(config["cd_in_path"], "chapters.ffmeta")
cleaned_chapter_path = os.path.join(config["cd_in_path"], "chapters_cleaned.ffmeta")

if not os.path.exists(chapter_path):
    show_error(texts[current_language]["no_chapters_file"])
    return

write_to_console("Starting to clean FFMeta...")
thread = threading.Thread(target=clean_ffmeta_thread, args=(chapter_path, cleaned_chapter_path))
thread.start()

def clean_ffmeta_thread(chapter_path, cleaned_chapter_path):
    try:
        chapter_action = config.get("chapter_action", "clean")
        keep_empty = config.get("chapter_keep_empty", False)

        write_to_console(f"Chapter action: {chapter_action}, Keep empty: {keep_empty}")

        with open(chapter_path, "r", encoding="utf-8") as f:
            lines = f.readlines()

        new_lines = []
        chapter_counter = 0

        for line in lines:
            stripped_line = line.strip()
            if stripped_line.startswith("title="):
                title_content = stripped_line[6:]
                
                if chapter_action == "clean":
                    if title_content == "":
                        if keep_empty:
                            new_lines.append(line)
                        else:

                            continue
                    else:
                        new_lines.append(line)
                
                elif chapter_action == "number":
                    chapter_counter += 1
                    chapter_title = f"{texts[current_language]['chapter']} {chapter_counter}"
                    new_lines.append(f"title={chapter_title}\n")
                    write_to_console(f"Renamed to: {chapter_title}")

  Why is the clean_chapters function not working ?

  


• FFprobe Throws JsonSyntaxException with NumberFormatException on Some Video Files [closed]

  3 avril, par Daydreamer067

  I'm using FFprobe through the Java wrapper to analyze video files :

  


      FFprobe ffprobe = new FFprobe("pathTo/ffprobe.exe");
    FFmpegProbeResult probeResult = ffprobe.probe(fichierTemp.getPath());


  


  This works fine for most files. However, on some video files, I get the following error :

  


  com.google.gson.JsonSyntaxException: java.lang.NumberFormatException: Expected an int but was 109893054318340751 at line 160 column 37 path $.chapters[0].id


  


  It seems like FFprobe is returning a chapter ID that is a long but it expected an int. How can I handle this situation and avoid this exception ?

  


  Is there a way to customize the JSON parsing or configure FFprobe to return int values ?

  


• Including FFmpeg.framework Into My IOS App

  28 mars, par Alpi

  I'm trying to manually integrate ffmpegkit.framework into my Expo Bare Workflow iOS app (built with React Native + native modules via Xcode) because the ffmpegkit will be deprecated and the binaries will be deleted.

  


  So far

  


  

  • I've downloaded the latest LTS release of FFmpegkit from here.

  


  • I've created 3 files : FFmpegModule.m , FFmpegModule.swift and SoundBud-Bridging-Header.

  


  • Added the frameworks to my projectDir/ios manually, which shows in my XCode under projectDir/Frameworks

  


  • Added all the frameworks into "Frameworks, Libraries and Embedded Content" and make them "Embed and Sign"

  


  • As Framework Search Path in Project Settings, I've set it to "$(PROJECT_DIR)" and recursive

  


  • In "Build Phases" I've added all the frameworks under "Embed Frameworks",set the destination to "Frameworks" and checked "Code Sign on Copy" to all of them and unchecked "Copy Only When Installing"

  


  • Also under "Link Binary With Libraries" I've added all the frameworks and marked them "Required"

  


  


  Here are the errors I'm getting :

  


  

  • The framework is not recognized by Swift (No such module 'ffmpegkit')

  


  • A build cycle error : Cycle inside SoundBud ; building could produce unreliable results.
Target 'SoundBud' has copy command from '.../Frameworks/ffmpegkit.framework' ...

  


  


  Below you can see my swift file and the ffmpegkit module file :
Swift :

  


  import Foundation
import ffmpegkit
import React

@objc(FFmpegModule)
class FFmpegModule: NSObject, RCTBridgeModule {

static func moduleName() -> String {
return "FFmpegModule"
}

@objc
func runCommand(_ command: String, resolver resolve: @escaping RCTPromiseResolveBlock, 
rejecter reject: @escaping RCTPromiseRejectBlock) {
FFmpegKit.executeAsync(command) { session in
  let returnCode = session?.getReturnCode()
  resolve(returnCode?.getValue())
}
}

@objc
static func requiresMainQueueSetup() -> Bool {
return false
}
}


  


  and the module :

  


  framework module ffmpegkit {

header "AbstractSession.h"
header "ArchDetect.h"
header "AtomicLong.h"
header "Chapter.h"
header "FFmpegKit.h"

  I can provide you with more info if you need it. I've been trying non stop for 7 days and it's driving me crazy. I would appreciate any help greatly
