In this article we will see how we can set audio delay to the MediaPlayer object in the python vlc module. VLC media player is a free and open-source portable cross-platform media player software and streaming media server developed by the VideoLAN project. MediPlyer object is the basic object in vlc module for playing the video. An audio channel or audio track is an audio signal communications channel in a storage device or mixing console, used in operations such as multi-track recording and sound reinforcement. Audio delay means that audio will get played after the delay time than normal time.
In order to do this we will use
audio_set_delaymethod with the MediaPlayer objectSyntax : media_player.audio_set_delay(n)
Argument : It takes integer i.e milliseconds as argument
Return : It returns 0 on success, -1 on error.
Below is the implementation
# importing vlc module import vlc # importing time module import time # creating vlc media player object media_player = vlc.MediaPlayer() # media object media = vlc.Media("death_note.mkv") # setting media to the media player media_player.set_media(media) # setting video scale media_player.video_set_scale(0.6) # setting audio delay of 100 milliseconds media_player.audio_set_delay(100) # setting volume media_player.audio_set_volume(80) # start playing video media_player.play() # wait so the video can be played for 5 seconds # irrespective for length of video time.sleep(5) |
Output :
Another example
Below is the implementation
# importing vlc module import vlc # importing time module import time # creating vlc media player object media_player = vlc.MediaPlayer() # media object media = vlc.Media("1mp4.mkv") # setting media to the media player media_player.set_media(media) # setting volume media_player.audio_set_volume(70) # setting video scale media_player.video_set_scale(0.6) # setting audio delay of 100 milliseconds media_player.audio_set_delay(100) # start playing video media_player.play() # wait so the video can be played for 5 seconds # irrespective for length of video time.sleep(5) |
