PyQt-thread. Get dynamically output
1er janvier 2020, par ZProI use PyQt-thread for parallel conversion of mp3 files to aac via ffmpeg.
Here is my code :class SubprocessThread(QThread):
signal = pyqtSignal('PyQt_PyObject')
def __init__(self, command, args):
QThread.__init__(self)
self.command = command
self.args = args
def __del__(self):
self.wait()
def run(self):
output = subprocess.check_output('{0} {1}'.format(self.command, self.args), shell=True).split()
self.signal.emit(output)And here is example of usage :
threads = []
for part in parts.keys():
args = "-i \'{0}.mp3\' -c:a aac -b:a {1}k \'{2}.m4a\'".format(
os.path.join(tmp_dir, str(part)),
int(self.bitrate_cbx.currentText()),
os.path.join(tmp_dir, str(part)))
print(args) # debug
ffmpeg_thread = SubprocessThread('ffmpeg', args)
ffmpeg_thread.signal.connect(self.on_data_ready)
threads.append(ffmpeg_thread)
ffmpeg_thread.start()
self.threads_count += 1I want to make progress bar, based on conversion, but ffmpeg always updates last string in his output (when conversion in progress).
Here is an example of ffmpeg output while files are converting :user@host$ ffmpeg -i '/home/user/001.mp3' -c:a aac -b:a 128k -vn '/home/user/test.m4a'

FFMPEG detect silence command runs correctly but does not give the silence duration
8 janvier 2020, par AizayousafI have a .wav audio file and I need to extract silence/pause duration in this file. I’m using ffmpeg with silence detect filter but I’m unable to understand why its not giving silence duration with this file while it gives result with other files. Can anyone help me to understand the out given below that why its not showing detected silences.
Input Command :
ffmpeg -i "input.wav" -af silencedetect=noise=-30dB:d=0.5 -f null -OutPut
