• Reading custom SEI message when decoding using VideoCodec (NVENC)

  23 avril 2018, par cloudraven

  I have a series of videos with custom information encoded in the sei message NAL. Is it possible to read that information when decoding using the Nvidia hardware decoder. If it is not supported, should I use FFMPEG compiled with NVENC support instead ?

  UPDATE :
  I want to decode the media and read the SEI message. I am streaming live video and including postprocessing info in the sei message. The client has to use that info to apply effects to the decoded media.
  Decoding the media as quickly as possible is important, and I want to do it in hardware. I assume that the Nvidia decoder must parse the NAL units to decode them. I would like to avoid duplicating work if possible.

  I'm making a discord bot for music

  


  This error occurs when trying to run play()

  


  TypeError : Cannot read properties of undefined (reading 'voice')

  


  play() :

  


  await interaction.deferReply();

    const query = interaction.options.get("query").value;
    const searchResult = await player
        .search(query, {
            requestedBy: interaction.user,
            searchEngine: QueryType.AUTO
        })
        .catch(() => {});
    if (!searchResult || !searchResult.tracks.length) return void interaction.followUp({ content: "No results were found!" });

    const queue = await player.createQueue(interaction.guild, {
        metadata: interaction.channel
    });

    try {
        if (!queue.connection) await queue.connect(interaction.member.voice.channel);
    } catch {
        void player.deleteQueue(interaction.guildId);
        return void interaction.followUp({ content: "Could not join your voice channel!" });
    }

    await interaction.followUp({ content: `⏱ | Loading your ${searchResult.playlist ? "playlist" : "track"}...` });
    searchResult.playlist ? queue.addTracks(searchResult.tracks) : queue.addTrack(searchResult.tracks[0]);
    if (!queue.playing) await queue.play();
} else if (interaction.commandName === "skip") {
    await interaction.deferReply();
    const queue = player.getQueue(interaction.guildId);
    if (!queue || !queue.playing) return void interaction.followUp({ content: "❌ | No music is being played!" });
    const currentTrack = queue.current;
    const success = queue.skip();
    return void interaction.followUp({
        content: success ? `✅ | Skipped **${currentTrack}**!` : "❌ | Something went wrong!"
    });
} else if (interaction.commandName === "stop") {
    await interaction.deferReply();
    const queue = player.getQueue(interaction.guildId);
    if (!queue || !queue.playing) return void interaction.followUp({ content: "❌ | No music is being played!" });
    queue.destroy();
    return void interaction.followUp({ content: "🛑 | Stopped the player!" });
} else {
    interaction.reply({
        content: "Unknown command!",
        ephemeral: true
