• Why does FFMPEG work with 1080p but doesn't work with 720p size… (code included)

  2 avril 2017, par JavaRunner

  I’ve uploaded my fully compiled code with its Makefile here :

  https://pastebin.com/xtCTj06F

  If I set 1280x720 I get the segmentation fault :

  [libx264 @ 0x7fdf4d25a600] using cpu capabilities: MMX2 SSE2Fast SSSE3 SSE4.2 AVX FMA3 AVX2 LZCNT BMI2

  sws_scale BEGIN
  
  ./MakeVideo.sh: line 2: 26422 Segmentation fault: 11  ./MakeVideo 1.mp4

  There’s some problem with this line :

  std::cout << "sws_scale BEGIN\n";
  
  sws_scale( sws_context, ( const uint8_t * const * ) &rgb, inLinesize, 0, frame->height, frame->data, frame->linesize );
  
  std::cout << "sws_scale END\n";

  but if I set the size of a video to 1920x1080 or to 320x240 - all works fine.

  Is that some sort of a magick ?? Or a bug ?

• My discord bot did work on local, but didn't work on heroku

  26 juillet 2022, par PeeP

  I depoly my discord bot on Heroku.
My bot sings normally when running on local,
If I run it on Heroku, the song will not play.
Full code is here

  


  @commands.command(name ="play")
    async def play_music(self, ctx, *keywords):
        if ctx.voice_client is None: 
            if ctx.author.voice:
                await ctx.author.voice.channel.connect()
            else:
                embed = discord.Embed(title = 'erro', description = "use after enter the channel 🤔", color = discord.Color.red())
                await ctx.send(embed=embed)
                raise commands.CommandError("Author not connected to a voice channel.")
        elif ctx.voice_client.is_playing():
            ctx.voice_client.stop()
        
        keyword = ' '.join(keywords)
        url = getUrl(keyword)
        await ctx.send(url)
        embed = discord.Embed(title = 'play', description = 'getting ready to play the song! 😎' , color = discord.Color.red())
        await ctx.send(embed=embed)


  


  It works up to the top code, but it doesn't seem to work on the bottom code.

  


          data = self.DL.extract_info(url, download = False)
        link = data['url']
        title = data['title']

        ffmpeg_options = {
            'options': '-vn',
            "before_options": "-reconnect 1 -reconnect_streamed 1 -reconnect_delay_max 5"
        }
        player = discord.FFmpegPCMAudio(link, **ffmpeg_options, executable = "./ffmpeg/bin/ffmpeg.exe")
        ctx.voice_client.play(player)
        
        embed = discord.Embed(title = 'play', description = f'{title} start play! 🐥' , color = discord.Color.blue())
        await ctx.send(embed=embed)
