Есть у меня условно видеофайл в котором 12 потоков (разные аудио дорожки, субтитры и т.д.). После конвертации с помощью ffmpeg и выбрав только два основных потока (один видео и один аудио) появляется третий поток, который промаркирован как бинарный, что в нем я не знаю. Вопрос такой, как его убрать? Если кто-то сталкивался, подскажите пожалуйста. Ниже приложу код
def run_ffmpeg(self, input_file, output_file, bitrate):
'''run ffmpeg command'''
try:
command = [arg.format(input_file=input_file, output_file=output_file, b_v=bitrate, b_a=self.b_a) for arg in self.ffmpeg_command] #run ffmpeg command which is in config
subprocess.run(command, check=True)
return True
except subprocess.CalledProcessError as e:
logging.error(f"Error running ffmpeg: {e}")
return False
def convert_files(self):
'''convert files to mp4 format'''
signal.signal(signal.SIGINT, self.signal_handler) #register signal handler
video_files = self.db_file.select_data()
for file_id, IsFilm, IsConverted, filename, nb_streams, streams in video_files: #iterate through files
self.file_id = file_id
if self.interrupted:
break
if nb_streams > 2: #check if file contains more than 2 streams
streams_info = json.loads(streams)
video_streams = [stream for stream in streams_info if stream['codec_type'] == 'video' and stream['index'] == 0]
audio_streams = [stream for stream in streams_info if stream['codec_type'] == 'audio' and 'rus' in stream.get('tags', {}).get('language', '') and stream['codec_name'] == 'ac3' and stream['disposition'].get('default', 0) == 1 or stream['index'] == 1]
if not IsConverted:
if len(video_streams) > 0 and len(audio_streams) > 0: #check if file contains video and audio streams
output_file = os.path.splitext(filename)[0] + '.mp4' #create output file
self.remove_list.append(output_file) #add file to remove list
self.db_file.update_status_of_conversion(file_id, 'converting', datetime.now().strftime(self.data_format))
try:
if IsFilm: #check if file is a film
bitrate = self.bitrate_video_film #set bitrate
else:
bitrate = self.bitrate_video_serials
self.run_ffmpeg(filename, output_file, bitrate) #run ffmpeg
success, check_result = self.check_integrity(output_file) #check if output file is corrupted
if success:
self.db_file.update_status_ending_conversion('done', datetime.now().strftime(self.data_format), check_result, file_id)
video_info = self.get_info.run_ffprobe(output_file) #get video info of converted file
if video_info:
streams = self.get_info.streams_data(video_info) #get streams info of converted file
self.db_file.update_files_table(output_file, True, len(streams), json.dumps(streams), file_id) #update table 'Files' with new data
else:
logging.error(f'{filename}: {check_result}')
self.db_file. update_of_checking_integrity('Error', datetime.now().strftime(self.data_format), 'Error: check logs', file_id) #update status of checking
except Exception as e: #catch errors
error_messege = str(e)
logging.error(f'{filename}: {error_messege}') #logging errors

Информация о потоках после конвертации:
[{"index": 0, "codec_name": "h264", "codec_long_name": "H.264 / AVC / MPEG-4 AVC / MPEG-4 part 10", "codec_type": "video", "disposition": {"default": 1}, "tags": {"language": "und", "title": null}}, {"index": 1, "codec_name": "ac3", "codec_long_name": "ATSC A/52A (AC-3)", "codec_type": "audio", "disposition": {"default": 1}, "tags": {"language": "rus", "title": null}}, {"index": 2, "codec_name": "bin_data", "codec_long_name": "binary data", "codec_type": "data", "disposition": {"default": 0}, "tags": {"language": "eng", "title": null}}]
Вот команда для конвертации, она хранится в отдельном json конфиге:
"ffmpeg_command": [
"ffmpeg",
"-i", "{input_file}",
"-c:v", "libx264",
"-c:a", "ac3",
"-map", "0:v:0",
"-map", "0:a:0",
"-b:v", "{b_v}",
"-b:a", "{b_a}",
"-preset:v", "ultrafast",
"-strict", "experimental",
"-movflags", "+faststart",
"{output_file}"
],
