• FFMPeg : how to establish a mms connection on the iPhone ?

  29 décembre 2011, par Winston

  I'd like to use ffmpeg to connect to a live stream, using the mms:// protocol and afterwards decode the WMA file to play on the iPhone.

  Which one of the following function should I use ? And how do I use it ?

  1) MMSContext http://ffmpeg.org/doxygen/trunk/structMMSContext.html

  or

  2) URLContext http://ffmpeg.org/doxygen/trunk/structURLContext.html

• How do I make my discord.py bot play a sound effect ?

  15 mai 2024, par Kronik71

  My bot is supposed to be some sort of jeopardy quiz show type of bot. /joinvc makes the bot connect to the call, however, I cant seem to make the bot make noise when its in a vc. Here's some of the code :

  


  @interactions.slash_command(
    name="press",
    description="Press the button"
)

async def press(ctx: interactions.ComponentContext):
    await ctx.send(f"{ctx.author.mention} has pressed the button")
    vc = ctx.author.voice.channel
    player = vc.create_ffmpeg_player('audiopath', after=lambda: print('done'))
    player.start()


  


  But whenever I use the /press command, I get this error AttributeError: 'GuildVoice' object has no attribute 'create_ffmpeg_player'

  


  Is it something I did wrong with ffmpeg ?

  


  I tried using a different way to write the code, basically grabbing the ffmpeg.exe path and the audio path, didn't work either. I just want the bot to play a small noise whenever someone uses /press command.

  


• how to build multiple video stream mux / mixer to virtual network camera

  9 juillet 2019, par Euan

  I’m looking for a software solution that can create a new virtual camera stream from a select-able range of cameras. Basically I want to do some calculations decide which camera is to be selected and switch the virtual camera to be transmitting the new stream.

  The stream needs to be low latency (at most 2 secs). I’m guessing I would need to transmux the input streams and selectively change source streams somehow. I then want to provide an ONVIF, or basic RTMP stream that a commercial DVR can connect to. I then want to duplicate this with a further number of virtual cameras using the same source feeds but different selected source at various times. I would be aiming to use a UDP message to select the source for each virtual camera.

  Cameras are H264, RTMP / RTSP, ONVIF.

  I haven’t tried anything yet as not sure what or where to go, or what to search for. I’m guessing ffmpeg would be a basis, or perhaps there is a better tool that can stitch together RTMP streams ?
