• avformat/flvenc : Avoid avio_write(pb, "", 0)

  19 mars 2024, par Andreas Rheinhardt

  avformat/flvenc : Avoid avio_write(pb, "", 0)
  When the compiler chooses to inline put_amf_string(pb, ""),
  
  the avio_write(pb, "", 0) can be avoided. Happens with
  
  Clang-17 with -O1 and higher and GCC 13 with -O2 and higher
  
  here.

• yt_dlp gives a strange message : "Seek to desired resync point failed. Seeking to earliest point available instead." and "File ended prematurely"

  16 septembre 2023, par nikita goncharov

  I have a discord bot (discord.py) in python and it can play music. Lastly it had trouble in playing the music, giving some random warnings but it mostly worked. But now it gives me this message :

  


  [matroska,webm @ 000001570fe92d40] Seek to desired resync point failed. Seeking to earliest point available instead.


  


  [matroska,webm @ 000001570fe92d40] File ended prematurely


  


  and also this one

  


  Warning: program compiled against libxml 211 using older 209


  


  As I saw this is a very common warning but I still have no Idea how to fix it.

  


  I will leave the code of the bot down bellow :

  


  Ytdlp setup (I have renamed the librarie to be youtube_dl)

  


  youtube_dl.utils.bug_reports_message = lambda: ''


ytdl_format_options = {
    'format': 'bestaudio/best',
    'outtmpl': '%(extractor)s-%(id)s-%(title)s.%(ext)s',
    'restrictfilenames': True,
    'noplaylist': True,
    'nocheckcertificate': True,
    'ignoreerrors': False,
    'logtostderr': True,
    'quiet': True,
    'no_warnings': False,
    'default_search': 'auto',
    'source_address': '0.0.0.0',  # bind to ipv4 since ipv6 addresses cause issues sometimes
}

ffmpeg_options = {
    'options': '-vn',
}

ytdl = youtube_dl.YoutubeDL(ytdl_format_options)


class YTDLSource(discord.PCMVolumeTransformer):
    def __init__(self, source, *, data, volume=0.5):
        super().__init__(source, volume)

        self.data = data

        self.title = data.get('title')
        self.url = data.get('url')
        self.duration = data.get('duration')
        img = ""
        imgs = ['']
        for image in data.get("thumbnails"):
            img = image["url"]
            imgs.append(image["url"])
        self.image = img
        self.thumbnails = imgs


  


  The play command :

  


  # if message.author.voice_client is not None:
try:
    print(1)
    sessionChannel = message.author.voice.channel
except:
    embedAns = discord.Embed(color=discord.Color.from_rgb(255, 201, 115))
    # embedImg.set_image(url=player.image)
    # embedImg.type = "image"
    embedAns.add_field(name="Player", value=f'To play audio you must join a voice channel!',
                       inline=True)
    embedAns.add_field(name="", value=f'*{message.author.name}*', inline=False)
    # embedImg.image.width = "800"
    await message.channel.send(embed=embedAns)
try:
    print(2)
    await message.author.voice.channel.connect(reconnect=False)
    print(2)
except:
    pass

try:
    print(3)
    load = await message.channel.send(
        f'Succesfuly joined voice channel to play music in {sessionChannel}')
    print(4)
    url = matched.group(1)
    player = await YTDLSource.from_url(url, loop=client.loop, stream=True)
    # Embed = await YTDLSource.from_url(url, loop=client.loop, stream=False)
    sessionChannel.guild.voice_client.play(player, after=lambda e: print(
        f'Player error: {e}') if e else None)
    await load.delete()
    sec = player.duration % 60
    temp = player.duration // 60
    min = temp % 60
    hour = temp // 60
    if hour == 0:
        timeStr = f"{min:02d}:{sec:02d}"

    embedImg.add_field(name="Player", value=f'Now playing: **{player.title}** \n `{timeStr}`',

• avcodec/hap : add "compressor" option to Hap encoder to disable secondary compression

  8 novembre 2016, par Tom Butterworth

  avcodec/hap : add "compressor" option to Hap encoder to disable secondary compression
  The secondary compression in Hap is optional, this change exposes that option to
  
  the user as some use-cases favour higher bitrate files to reduce workload
  
  decoding.
  
  Adds "none" or "snappy" as options for "compressor". Selecting "none" disregards
  
  "chunks" option : chunking is only of benefit decompressing Snappy.
