• HLS-streaming on VLC - cookies alternative

  5 juillet 2018, par unicornslayer

  I’m trying to build a streaming web api which creates m3u8 playlists of .ts files in .net core.

  I’ve built the live streaming option and it works fine on vlc.

  For example, in VLC -> File -> Open Network put my link : http://localhost:39986/api/Stream/MyChannel/index.m3u8 and VLC gives me the live version of the channel.

  But I need to implement the option of starting a video from a fixed time : http://localhost:39986/api/Stream/MyChannel/index.m3u8?timeStr="2018-07-04T17:16:01". In this case, I would need to create a session to know from which point to create the playlist, right ?[1]

  If so, sessions require an ID stored as a Cookie (right ?[2]). But from what I’ve read and what I’ve tested, vlc doesn’t support cookies.

  So my question is : is there any workaround for this scenario ?[3]

  It’s an university project and I am very confused about this task.

• The problem with pydub.AudioSegment.from_file (ffmpeg)

  7 septembre 2024, par akkoolda

  I'm trying to make a normal voice recording discord. When I try to convert an Audio Data object, an error occurs. I've already tried everything I can, I can't solve the problem.

  


  Here is the code, the error occurs in the seg variable :

  


  async def once_done(sink: discord.sinks.MP3Sink, channel: discord.TextChannel, *args):
        words_list = []
        audio_segs: list[pydub.AudioSegment] = []
        longest = pydub.AudioSegment.empty()
        files: list[discord.File] = []

        for user_id, audio in sink.audio_data.items():
            try:
                payload: FileSource = {
                    "buffer": audio.file.read(),
                    "mimetype": "audio/mp3"  # Указываем тип аудиофайла
            }

                #audio.on_format("mp3")
                seg = pydub.AudioSegment.from_file(audio.file, format="mp3")

Solving the error, how else can you normally record user audio


  


  How can I fix this, or maybe there are some other options ?
