  • Assembling frames into a video in Node.js using fluent-ffmpeg [closed]

    14 novembre 2024, par Andrei

    I have the original video and it's modified frames in a folder. Now I want to assemble the modified frames into a new video. I also want to take the audio from the original video and add it to the new video.

    


    My latest code is this using fluent-ffmpeg. But it's not working.

    


    await new Promise((resolve, reject) => {
  ffmpeg(path.join(processedFramesDir, "frame-%d.png"))
    .inputOptions(["-framerate 30", "-start_number 1"])
    .input(videoPath)
    .outputOptions([
      "-c:v",
      "libx264",
      "-c:a",
      "copy",
      "-shortest",
      "-r",
      "30",
      "-pix_fmt",
      "yuv420p",
    ])
    .outputOptions(["-map 0:v:0", "-map 1:a:0"])
    .save(outputVideoPath)
    .on("start", (commandLine) => {
      console.log("FFmpeg command: " + commandLine);
    })
    .on("stderr", (stderrLine) => {
      console.log("FFmpeg stderr: " + stderrLine);
    })
    .on("end", resolve)
    .on("error", (err, stdout, stderr) => {
      console.error("Error assembling video:", err);
      console.error("FFmpeg stderr:", stderr);
      reject(err);
    });
});


    


    I get this error even though the frames exist and they are valid pngs :&#xA;FFmpeg command: ffmpeg -framerate 30 -start_number 1 -i /tmp/video-processing-CyULOE/processedFrames/frame-%05d.png -i /tmp/video-processing-CyULOE/input.mp4 -y -c:v libx264 -c:a copy -shortest -r 30 -pix_fmt yuv420p -map 0:v:0 -map 1:a:0 /tmp/video-processing-CyULOE/output.mp4 2024-11-13 23:40:27 FFmpeg stderr: ffmpeg version 4.1.11-0&#x2B;deb10u1 Copyright (c) 2000-2023 the FFmpeg developers 2024-11-13 23:40:27 FFmpeg stderr:   built with gcc 8 (Debian 8.3.0-6) 2024-11-13 23:40:27 FFmpeg stderr:   configuration: --prefix=/usr --extra-version=0&#x2B;deb10u1 --toolchain=hardened --libdir=/usr/lib/x86_64-linux-gnu --incdir=/usr/include/x86_64-linux-gnu --arch=amd64 --enable-gpl --disable-stripping --enable-avresample --disable-filter=resample --enable-avisynth --enable-gnutls --enable-ladspa --enable-libaom --enable-libass --enable-libbluray --enable-libbs2b --enable-libcaca --enable-libcdio --enable-libcodec2 --enable-libflite --enable-libfontconfig --enable-libfreetype --enable-libfribidi --enable-libgme --enable-libgsm --enable-libjack --enable-libmp3lame --enable-libmysofa --enable-libopenjpeg --enable-libopenmpt --enable-libopus --enable-libpulse --enable-librsvg --enable-librubberband --enable-libshine --enable-libsnappy --enable-libsoxr --enable-libspeex --enable-libssh --enable-libtheora --enable-libtwolame --enable-libvidstab --enable-libvorbis --enable-libvpx --enable-libwavpack --enable-libwebp --enable-libx265 --enable-libxml2 --enable-libxvid --enable-libzmq --enable-libzvbi --enable-lv2 --enable-omx --enable-openal --enable-opengl --enable-sdl2 --enable-libdc1394 --enable-libdrm --enable-libiec61883 --enable-chromaprint --enable-frei0r --enable-libx264 --enable-shared 2024-11-13 23:40:27 FFmpeg stderr:   libavutil      56. 22.100 / 56. 22.100 2024-11-13 23:40:27 FFmpeg stderr:   libavcodec     58. 35.100 / 58. 35.100 2024-11-13 23:40:27 FFmpeg stderr:   libavformat    58. 20.100 / 58. 20.100 2024-11-13 23:40:27 FFmpeg stderr:   libavdevice    58.  5.100 / 58.  5.100 2024-11-13 23:40:27 FFmpeg stderr:   libavfilter     7. 40.101 /  7. 40.101 2024-11-13 23:40:27 FFmpeg stderr:   libavresample   4.  0.  0 /  4.  0.  0 2024-11-13 23:40:27 FFmpeg stderr:   libswscale      5.  3.100 /  5.  3.100 2024-11-13 23:40:27 FFmpeg stderr:   libswresample   3.  3.100 /  3.  3.100 2024-11-13 23:40:27 FFmpeg stderr:   libpostproc    55.  3.100 / 55.  3.100 2024-11-13 23:40:27 FFmpeg stderr: [png @ 0x5630fb89a880] Invalid PNG signature 0x52494646F8A20000. 2024-11-13 23:40:27 FFmpeg stderr: [png @ 0x5630fb89a880] Invalid PNG signature 0x52494646C89F0000. 2024-11-13 23:40:27 FFmpeg stderr: [png @ 0x5630fb89a880] Invalid PNG signature 0x524946464EA10000. 2024-11-13 23:40:27 FFmpeg stderr: [png @ 0x5630fb89a880] Invalid PNG signature 0x5249464628A40000. 2024-11-13 23:40:27 FFmpeg stderr: [png @ 0x5630fb89a880] Invalid PNG signature 0x52494646AAA30000. 2024-11-13 23:40:27 FFmpeg stderr: [png @ 0x5630fb89a880] Invalid PNG signature 0x524946467CA10000. 2024-11-13 23:40:27 FFmpeg stderr: [png @ 0x5630fb89a880] Invalid PNG signature 0x52494646AAA30000. 2024-11-13 23:40:27 FFmpeg stderr: [png @ 0x5630fb89a880] Invalid PNG signature 0x52494646BAA10000. 2024-11-13 23:40:27 FFmpeg stderr: [png @ 0x5630fb89a880] Invalid PNG signature 0x52494646ACA30000. 2024-11-13 23:40:27 FFmpeg stderr: [png @ 0x5630fb89a880] Invalid PNG signature 0x5249464670A80000. 2024-11-13 23:40:27 FFmpeg stderr: [png @ 0x5630fb89a880] Invalid PNG signature 0x52494646E8A60000. 2024-11-13 23:40:27 FFmpeg stderr: [png @ 0x5630fb89a880] Invalid PNG signature 0x524946469AA60000. 2024-11-13 23:40:27 FFmpeg stderr: [png @ 0x5630fb89a880] Invalid PNG signature 0x5249464672A90000. 2024-11-13 23:40:27 FFmpeg stderr: [png @ 0x5630fb89a880] Invalid PNG signature 0x52494646B8A50000. 2024-11-13 23:40:27 FFmpeg stderr: [png @ 0x5630fb89a880] Invalid PNG signature 0x52494646AAA80000. 2024-11-13 23:40:27 FFmpeg stderr: [png @ 0x5630fb89a880] Invalid PNG signature 0x52494646A0A70000. 2024-11-13 23:40:27 FFmpeg stderr:     Last message repeated 1 times 2024-11-13 23:40:27 FFmpeg stderr: [png @ 0x5630fb89a880] Invalid PNG signature 0x5249464646A80000. 2024-11-13 23:40:27 FFmpeg stderr: [image2 @ 0x5630fb898a40] decoding for stream 0 failed 2024-11-13 23:40:27 FFmpeg stderr: [image2 @ 0x5630fb898a40] Could not find codec parameters for stream 0 (Video: png, none(pc)): unspecified size 2024-11-13 23:40:27 FFmpeg stderr: Consider increasing the value for the &#x27;analyzeduration&#x27;

  • I cannot play a mp3 file on Discord's voice channel using discord.py

    1er décembre 2024, par ra1ned

    I am creating a discord bot that plays lofi for me. It does not play a song for me even though it shows a green indicator on a voice channel.

    &#xA;

    Here's what I've written :

    &#xA;

    if message.content == "!join":&#xA;    await message.author.voice.channel.connect()&#xA;    await message.channel.send("Successfully connected")&#xA;&#xA;if message.content == "!play":&#xA;    if message.guild.voice_client is None: &#xA;        await message.channel.send("use !join")&#xA;        return&#xA;    &#xA;    await message.channel.send("playing a song rn")&#xA;    print(&#x27;*** playing a song rn&#x27;)&#xA;    &#xA;    message.guild.voice_client.play(discord.FFmpegPCMAudio(&#x27;lofi.mp3&#x27;))&#xA;

    &#xA;

    I put FFmpeg.exe and lofi.mp3 in the same directory as this script.&#xA;Also, it is strange that FFmpeg does not return any exception nor output on console although it seems to have failed to load the file. I have seen people who had the same problem, but it seems like that they get some error messages, unlike me.

    &#xA;

    Here's the output on console after using !join

    &#xA;

    2024-12-01 16:59:39 INFO     discord.voice_state Connecting to voice...&#xA;2024-12-01 16:59:39 INFO     discord.voice_state Starting voice handshake... (connection attempt 1)&#xA;2024-12-01 16:59:40 INFO     discord.voice_state Voice handshake complete. Endpoint found: japan8946.discord.media&#xA;2024-12-01 16:59:40 INFO     discord.voice_state Voice connection complete.&#xA;

    &#xA;

    after using !play, it only displays the message I wrote :

    &#xA;

    *** playing a song rn&#xA;

    &#xA;

    Can someone help me with this ?

  • Need help accessing the key when trying to decrypt .ts files via ffmpeg

    4 juillet 2024, par Diz

    I have downloaded all the individual .ts files and the corresponding m3u8 file from a VOD and I now want to merge them together into a single watchable file.&#xA;The problem is, that the .ts files are encrypted and don't understand how to access the key.

    &#xA;

    Here's the beginning of the m3u8 file :

    &#xA;

    #EXTM3U&#xA;#EXT-X-VERSION:3&#xA;#EXT-X-TARGETDURATION:4&#xA;#EXT-X-PLAYLIST-TYPE:EVENT&#xA;#EXT-X-MEDIA-SEQUENCE:6484&#xA;#EXT-X-KEY:METHOD=AES-128,URI="irvine://aes",KEYFORMATVERSIONS="1",IV=0x1E9ABA2B3C916D47D592D9B1E7674F4B&#xA;#EXT-X-PROGRAM-DATE-TIME:2024-05-25T07:24:59.682Z&#xA;#EXTINF:4.004,&#xA;index_1_6484.ts&#xA;#EXT-X-PROGRAM-DATE-TIME:2024-05-25T07:25:03.686Z&#xA;#EXTINF:4.004,&#xA;index_1_6485.ts&#xA;#EXT-X-PROGRAM-DATE-TIME:2024-05-25T07:25:07.690Z&#xA;#EXTINF:4.004,&#xA;index_1_6486.ts&#xA;#EXT-X-PROGRAM-DATE-TIME:2024-05-25T07:25:11.694Z&#xA;#EXTINF:4.004,&#xA;index_1_6487.ts&#xA;...&#xA;&#xA;

    &#xA;

    As far as I understood I only have the initialization vector and I need to access the URI to get the actual key.

    &#xA;

    I have tried to decrypt the playlist with the following command :

    &#xA;

    ffmpeg -i index_1.m3u8 -c copy output.ts&#xA;

    &#xA;

    But I would always get the following errors :

    &#xA;

    Unable to open key file irvine://aes&#xA;Error when loading first segment &#x27;index_1_6484.ts&#x27;&#xA;Error opening input: Invalid data found when processing input&#xA;Error opening input file index_1.m3u8.&#xA;Error opening input files: Invalid data found when processing input&#xA;

    &#xA;

    I have also tried just decrypting a single .ts file to start with, with similar results.

    &#xA;

    ffmpeg -decryption_key 1E9ABA2B3C916D47D592D9B1E7674F4B -i index_1_6484.ts -codec copy index_1_6484_out.ts&#xA;

    &#xA;
