• using ffmpeg.js to play H265 video, only play hvc1 format, can't play hev1 format, is there anyway to play hev1 ?

  1er novembre 2019, par Alex

  I compiled ffmpeg into ffmpeg.js and ffmpeg.wasm by using emscripten, so that it can run in the browser and play H265 video.

  However, I found that only the hvc1 format can be played.
  Like that：

  Stream #0:0(und): Video: hevc (Main) (hvc1 / 0x31637668), yuv420p(tv, bt709, progressive), 1280x720, 854 kb/s, 25 fps, 25 tbr, 12800 tbn, 25 tbc (default)

  and the hev1 format cannot be played.Like that :

  Stream #0:0(und): Video: hevc (Main) (hev1 / 0x31766568), yuv420p(tv, progressive), 1920x1080 [SAR 1:1 DAR 16:9], 829 kb/s, 25 fps, 25 tbr, 12800 tbn, 25 tbc (default)

  Web browser’s Console has this errors

  ffplay can play these two, why can only play hvc1 after compiling into ffmpeg.js and ffmpeg.wasm ?

• VoiceClient.play() doesn't play any audio

  13 juin 2019, par sickoofer2

  I am trying to make a music bot in discord.py, but whenever I tried to play audio using VoiceClient.play(), it never played anything, just stayed in the voice channel.

  async def play(ctx):
  
      for VoiceClient in client.voice_clients:
  
          if VoiceClient.guild == ctx.guild:
  
              await VoiceClient.play(discord.FFmpegPCMAudio('song.mp3'))
  
              embed = discord.Embed(title=f'⬅  {ctx.author.mention},  I am now playing that song.', color=0x51BDEF)
  
              await ctx.send(embed=embed)

  There weren’t any error messages either, just doesn’t play anything
