  • 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;

  • How can I publish an RTSP stream to a MediaMTX instance with TLS encryption configured ? [closed]

    15 février 2024, par cmd

    I have an instance of (MediaMTX) running on my laptop. I have an Amcrest IP camera. I can publish the camera's RTSP stream to the server so that the stream can be accessed from the MediaMTX instance.

    &#xA;

    However, I want to encrypt the stream. On the Github page for MediaMTX, they detail how TLS encryption can be enabled for incoming and outgoing RTSP streams by generating a server.key and server.crt and editing lines in the .yml configuration file. Streams can then be published and read with RTSPS and port 8322.

    &#xA;

    I have followed these steps, and set up the following path for my IP camera in the .yml :

    &#xA;

    ###############################################&#xA;# Path settings&#xA;&#xA;# Settings in "paths" are applied to specific paths, and the map key&#xA;# is the name of the path.&#xA;# Any setting in "pathDefaults" can be overridden here.&#xA;# It&#x27;s possible to use regular expressions by using a tilde as prefix,&#xA;# for example "~^(test1|test2)$" will match both "test1" and "test2",&#xA;# for example "~^prefix" will match all paths that start with "prefix".&#xA;paths:&#xA;&#xA;  cam1:&#xA;    source: rtsp://user:password@192.168.68.142:554&#xA;    runOnInit: ffmpeg -i rtsp://user:password@192.168.68.142:554 -c:v copy -c:a copy -f rtsp rtsps://localhost:8322/stream/cam1&#xA;

    &#xA;

    But I am getting the following output from my MediaMTX instance when it runs :

    &#xA;

    2024/02/15 18:20:59 INF [path cam1] [RTSP source] ready: 2 tracks (H264, MPEG-4 Audio)&#xA;Input #0, rtsp, from &#x27;rtsp://user:password@192.168.68.142:554&#x27;:&#xA;  Metadata:&#xA;    title           : Media Server&#xA;  Duration: N/A, start: 0.030000, bitrate: N/A&#xA;  Stream #0:0: Video: h264 (Main), yuv420p(progressive), 1920x1080, 100 tbr, 90k tbn&#xA;  Stream #0:1: Audio: aac (LC), 16000 Hz, mono, fltp&#xA;Stream mapping:&#xA;  Stream #0:0 -> #0:0 (copy)&#xA;  Stream #0:1 -> #0:1 (copy)&#xA;2024/02/15 18:21:00 INF [RTSPS] [conn [::1]:60147] opened&#xA;2024/02/15 18:21:00 INF [RTSPS] [session 07a8f23e] created by [::1]:60147&#xA;2024/02/15 18:21:00 INF [RTSPS] [conn [::1]:60147] closed: path &#x27;stream/cam1&#x27; is not configured&#xA;2024/02/15 18:21:00 INF [RTSPS] [session 07a8f23e] destroyed: not in use&#xA;[out#0/rtsp @ 00000225c75fe9c0] Could not write header (incorrect codec parameters ?): Server returned 400 Bad Request&#xA;Conversion failed!&#xA;2024/02/15 18:21:00 INF [path cam1] runOnInit command exited: command exited with code 3486501640&#xA;2024/02/15 18:21:29 WAR [path cam1] [RTSP source] 10 RTP packets lost&#xA;2024/02/15 18:21:33 WAR [path cam1] [RTSP source] 2 RTP packets lost&#xA;2024/02/15 18:21:39 WAR [path cam1] [RTSP source] 11 RTP packets lost&#xA;

    &#xA;

    I have no errors and was able to publish the stream with the same path configuration (using rtsp ://, not rtsps ://) when using no encryption. What possible solutions can I try ?

  • How to display quick preview of output generated from FFMPEG command ? [android]

    6 février 2019, par akash varlani

    Basically I am developing a video editing app that lets user choose some of their images and create video slide show with music.

    I am using FFMPEG to generate video slide show from images but the problem is I can only show preview of the video after executing FFMPEG command.

    Is googled so many blogs and all and I know there is a possible way available to display preview of the output.

    Check below image from reference app. I am developing something similar to this app. There is an option to replace the image in video. This app displays instant preview once I change the image.

    enter image description here

    Here is the link of the reference app if anyone wants to check :

    Clicking an EXPORT button this app lets you generate video output. I can do that as I know FFMPEG and how to generate OUTPUT FILE using FFMPEG but what I don’t know is how to display quick preview of OUTPUT VIDEO before generating actual VIDEO FILE.

    On my UBUNTU device I can view output of FFMPEG command using FFPLAY tool but how to do the same on android device.

    Some useful link :
