Wenden Sie mehrere Textfilter gleichzeitig an und verbrennen Sie in ein Video zum Bildunterschriften ohne Neukodierung u ⇐ Python

[Anonymous]

Gibt es eine Möglichkeit, Text in ein Video zu verbrennen, ohne neu zu kennern? Ich frage dies, weil der Neukodierprozess beim Schreiben in WebM rund 0,1x Geschwindigkeit auf meinem Gerät verläuft. Alternativ, wenn es eine schnellere Möglichkeit gibt, qualitativ hochwertige Videos schnell zu machen und gleichzeitig neu zu kodieren, wäre dies großartig. Ich erinnere mich vage an jemanden, der in eine temporäre Datei geschrieben hat, um dieses Problem zu lösen.

Code: Select all

def processVideo(self):
print("creating video")

# File location management
font_path = self.input_path / "CalSans-Regular.ttf"
background_path = self.input_path / "new_video_background.webm"
audio_path = self.sound_output_path
video_ouput_path = self.parent_path / "new_result.webm"
sound_input = ffmpeg.input(str(audio_path))
video_input = ffmpeg.input(str(background_path))

# Adding captions
print(self.text_caption)
previous_timepoint = 0
for caption, timepoint in zip(self.text_caption, self.timepoints, strict=False):
# Text caption and timepooints are lists where the end of the words in text_caption correspond
# to the timepoint with the same index in timepoint
video_input = video_input.drawtext(
text=caption,
fontfile = font_path,
x='w-text_w/2',
y='h-text_h/2',
escape_text=True,
fontsize= 32,
bordercolor = "black",
borderw = 4,
enable=f'between(t,{previous_timepoint},{timepoint["timeSeconds"]})'
)
previous_timepoint = timepoint["timeSeconds"]

# Combining sound and video and writing output
command = ffmpeg.output(sound_input, video_input, str(video_ouput_path), codec='copy').overwrite_output().global_args('-shortest')
print("args =", command)
print(command.get_args())
command.run()
print("done!")
