  avutil/tests/color_utils : reduce accuracy threshold to pass to 1e-7
  Fixes FATE on a variety of configurations due to accuracy problems in
  
  floating point math. Most constants tested against here are not even
  
  specified with 7 decimal digits.

• DVR + FFMPEG + IOS Authentication and Live Streaming Fails

  6 août 2013, par user1744691

  How to grab video from a DVR using ffmpeg and DVR is password protected. Is there a way to grab live stream from IP-Cam connected to DVR.

  I was able to stream a channel (may be recorded video) but whenever i tried to connect to a DVR could not get it done.

  this
  http://www.wowza.com/_h264/BigBuckBunny_175k.mov and this rtsp ://live.sabah.com.tr:443/atv/atv3/
  link works great for getting me stream
  but when i try my DVR's (http://admril:56789@mysite.com) (mysite.com = 213.115.94.108) link it fails to establish a connection using FFMEG.

  I have used a variety of variation of DVR's url but all in vein.

  Please let me know where i am wrong and how i can get live stream.

• 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()

    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="):

                if chapter_action == "clean":
                    if title_content == "":
