lavc/qsvenc_hevc : restore the default gop size
11 août 2023, par Haihao Xianglavc/qsvenc_hevc : restore the default gop size
commit a3c0a3e changed the default settings and expected the runtime can
choose a best value. However the runtime doesn't set a valid gop size
for hevc encoder, hence the output steam is non-seekable, which is
inconvenient to user [1][2][1] https://github.com/intel/media-driver/issues/1576

FileNotFoundError when extracting audio from recently saved video using FFMPEG"
3 août 2023, par Peter LongScenario : I'm using this tool to record tiktok live. I write another script to call the
main.pytool because I want to add some additional options, for example, to extract the audio of the live video that is recorded

FFMPEG is used to extract the audio. First the video is saved (with FFMPEG) and after I want to extract the audio of that video (again with FFMPEG). The path where the video is recorded and saved is
C:\Users\Administrator\Desktop\tiktok

The problem is that I see the file and it is saved, but this error is generated as output :
FileNotFoundError: [WinError 2] The system cannot find the file specified

I can't figure out why it doesn't detect the last saved video file in general


I try with this


import os
import subprocess
import time
from moviepy.editor import VideoFileClip

def main():
 # Command to run main.py and record the video
 cmd = 'python main.py -user ryzebenny -output "C:\\Users\\Administrator\\Desktop\\tiktok" -ffmpeg -duration 30 --auto-convert'
 subprocess.run(cmd, shell=True)

 # Wait for the video file to appear in the folder
 wait_for_video("C:\\Users\\Administrator\\Desktop\\tiktok")

 # Extract audio from recorded video
 video_filename = find_latest_file("C:\\Users\\Administrator\\Desktop\\tiktok", ".mp4")
 if video_filename:
 video_path = os.path.join("C:\\Users\\Administrator\\Desktop\\tiktok", video_filename)
 audio_filename = video_filename.replace(".mp4", ".mp3")
 audio_path = os.path.join("C:\\Users\\Administrator\\Desktop\\tiktok", audio_filename)

 video_clip = VideoFileClip(video_path)
 audio_clip = video_clip.audio
 audio_clip.write_audiofile(audio_path)
 audio_clip.close()
 video_clip.close()
 print(f"Audio extraction completed: {audio_filename}")
 else:
 print("No video files found.")

def wait_for_video(directory):
 max_wait_time = 60 # Maximum time to wait in seconds
 start_time = time.time()
 while time.time() - start_time < max_wait_time:
 if find_latest_file(directory, ".mp4"):
 break
 time.sleep(1)

def find_latest_file(directory, extension):
 list_of_files = [f for f in os.listdir(directory) if f.endswith(extension) and os.path.isfile(os.path.join(directory, f))]
 if list_of_files:
 return max(list_of_files, key=os.path.getctime)
 return None

if __name__ == "__main__":
 main()


but i get this error

FileNotFoundError: [WinError 2] The system cannot find the file specified: 'TK_ryzebenny_2023.08.03_15-57-09.mp4'

Instead, I expect that once I save the video (in .mp4) the audio of that video will be extracted afterwards
