• What is KeyError : 'twoColumnSearchResultsRenderer' (Python, youtube_dl)

  2 octobre 2020, par Elara Jayde

  I have been writing a Discord bot in Python using discord.py version 1.5.0. Only recently have I began adding music commands to it with youtube_dl, youtube_search, and ffmpeg. I can play the audio entirely, as well as pull titles, durations, thumbnails, etc. The only problem I have had thus far is that when I store the Youtube URL in a list and then index it on the "next" command then it returns an error saying "KeyError : 'twoColumnSearchResultsRenderer'" and I cannot find any other examples of this being returned back to the user. If someone could help me understand what the issue is then that would be greatly appreciated.

  @bot.command()
    async def play(ctx, *args):
        #local variables
        global queueList
        server = ctx.message.guild
        voiceChannel = server.voice_client
        keywords = listtostring(args)
        results = ast.literal_eval(YoutubeSearch(keywords, max_results=1).to_json())
        test = results['videos']
        print(test[0])
        vidId = test[0]['id']
        vidThumbnail = test[0]['thumbnails'][0]
        vidUrl = "https://www.youtube.com/watch?v={}".format(vidId)
        queueList.append(vidUrl)

        if args and ctx.message.author.voice:

            async with ctx.typing():

                player = await YTDLSource.from_url(queueList[0], loop=client.loop)
                await ctx.send("`{}` added to the queue!".format(player.title))

                try: 
                    voiceChannel.play(player, after=lambda e: print('Player error: %s' % e) if e else None)
                    nowPlaying = discord.Embed(
                        title = "Now playing",
                        description = "Now playing **{}**".format(player.title),
                        color = rupertColor
                    )
                    nowPlaying.set_thumbnail(url=vidThumbnail)

                    await ctx.send(embed = nowPlaying) #('**Now playing:** {}'.format(player.title))
                except: 
                    print("failed playing")

                del(queueList[0])

        else:
            await stop(ctx)
            async with ctx.typing():
                player = await YTDLSource.from_url(str(queueList[0]), loop=client.loop)
                try:

• ffmpeg combining audio tracks on copy

  22 janvier 2024, par janeden

  I tried to copy all streams (video, audio, subtitle) and add a tag with the following command in order to play the files using QuickTime player :

  


  ffmpeg -i in.mp4 -vcodec copy -tag:v hvc1 -acodec copy -scodec copy -map 0 out.mp4


  


  The resulting file does open with QuickTime player, and the video/subtitles play fine, but the two audio tracks (E-AC3 in English and German) from the input file cannot be selected (View → Languages → None) and are in fact merged into each other while playing the video, even though both tracks are shown separately in Inspector → Audio Details and VLC handles them correctly. Is this a bug in QuickTime player, or would I need to add another option for QuickTime ?

  


• libav/ffmpeg : where is data buffer storage ?

  1er juillet 2020, par nguyenthachung

  I'm using libav/ffmpeg to play some DASH livestream.

  


  My case : player is playing normally -> pause for 3 4 minutes -> play again -> Player continue to play without interrupted, not jump to realtime.

  


  Is libav/ffmpeg cached buffer or stored to somewhere ?
