• how spotify and other music players implement cross fading between music

  11 janvier 2023, par Arihant Jain

  I was working on a media streaming project and thought of implementing a cross fade between the next and current playing song.

  


  HLS is used for streaming music and .m3u8 file is presigned by cloudfront.

  


  Any help will be appreciated.

  I'm new in python and i'm using pydub modules to play mp3 track.

  



  Here is my simple code to play mp3 :

  



  #Let's play some mp3 files using python!

from pydub import AudioSegment
from pydub.playback import play

song = AudioSegment.from_mp3("/media/rajendra/0C86E11786E10256/05_I_Like_It_Rough.mp3")
play(song)


  



  When i run this program, it says :

  



  */usr/bin/python3.4 /home/rajendra/PycharmProjects/pythonProject5/myProgram.py&#xA;/usr/local/lib/python3.4/dist-packages/pydub/utils.py:161: RuntimeWarning: Couldn&#x27;t find ffmpeg or avconv - defaulting to ffmpeg, but may not work&#xA;  warn("Couldn&#x27;t find ffmpeg or avconv - defaulting to ffmpeg, but may not work", RuntimeWarning)&#xA;/usr/local/lib/python3.4/dist-packages/pydub/utils.py:174: RuntimeWarning: Couldn&#x27;t find ffplay or avplay - defaulting to ffplay, but may not work&#xA;  warn("Couldn&#x27;t find ffplay or avplay - defaulting to ffplay, but may not work", RuntimeWarning)&#xA;Traceback (most recent call last):&#xA;  File "/home/rajendra/PycharmProjects/pythonProject5/myProgram.py", line 11, in <module>&#xA;    song = AudioSegment.from_mp3("/media/rajendra/0C86E11786E10256/05_I_Like_It_Rough.mp3")&#xA;  File "/usr/local/lib/python3.4/dist-packages/pydub/audio_segment.py", line 355, in from_mp3&#xA;    return cls.from_file(file, &#x27;mp3&#x27;)&#xA;  File "/usr/local/lib/python3.4/dist-packages/pydub/audio_segment.py", line 339, in from_file&#xA;    retcode = subprocess.call(convertion_command, stderr=open(os.devnull))&#xA;  File "/usr/lib/python3.4/subprocess.py", line 533, in call&#xA;    with Popen(*popenargs, **kwargs) as p:&#xA;  File "/usr/lib/python3.4/subprocess.py", line 848, in __init__&#xA;    restore_signals, start_new_session)&#xA;  File "/usr/lib/python3.4/subprocess.py", line 1446, in _execute_child&#xA;    raise child_exception_type(errno_num, err_msg)&#xA;FileNotFoundError: [Errno 2] No such file or directory: &#x27;ffmpeg&#x27;&#xA;&#xA;Process finished with exit code 1*&#xA;</module>
