• typeError when using ffmpeg with buffer in NodeJS ["argument must be of type string or an instance of Buffer"]

  16 mars 2021, par coolps811

  I am trying to covert buffer data into the correct mp4 video format. However I am getting an error : "UnhandledPromiseRejectionWarning : TypeError [ERR_INVALID_ARG_TYPE] : The "data" argument must be of type string or an instance of Buffer, TypedArray, or DataView. Received an instance of FfmpegCommand". How can I fix this ?

  


  router.post("/download", (req, res, next) => {
  axios({
    method: "get",
    url: req.body.url,
    responseType: "arraybuffer",
  }).then(function (response) {
    const data = new Uint8Array(Buffer.from(response.data));

    const proc = new ffmpeg(data)
      .videoCodec("libx264")
      .outputOptions(["-movflags isml+frag_keyframe"])
      .toFormat("mp4")
      //.seekInput(offset) this is a problem with piping
      .on("error", function (err, stdout, stderr) {
        console.log("an error happened: " + err.message);
        console.log("ffmpeg stdout: " + stdout);
        console.log("ffmpeg stderr: " + stderr);
      })
      .on("end", function () {
        console.log("Processing finished !");
      })
      .on("progress", function (progress) {
        console.log("Processing: " + progress.percent + "% done");
      });

    fs.writeFile("Assets/test.mp4", proc, callback);
  });

  const callback = (err) => {
    if (err) throw err;
    console.log("It's saved!");
  };
});


  


• How do I read an mp4 file directly into moviepy from S3 ?

  9 novembre 2022, par racket99

  Any idea how to read an S3 mp4 file directly into moviepy ?

  



  I have tried,

  



  import boto3
from io import BytesIO
from moviepy.editor import *

client = boto3.client('s3')
obj =  client.get_object(Bucket='some-bucket', Key='some-file')
VideoFileClip(BytesIO(obj['Body'].read())) 


  



  but I am getting,

  



  Traceback (most recent call last):&#xA;File "<stdin>", line 1, in <module>&#xA;File "/<path>/lib/python3.6/site-packages/moviepy/video/io/VideoFileClip.py", line 91, in __init__&#xA;fps_source=fps_source)&#xA;File "/<path>/lib/python3.6/site-packages/moviepy/video/io/ffmpeg_reader.py", line 33, in __init__&#xA;fps_source)&#xA;File "/<path>/lib/python3.6/site-packages/moviepy/video/io/ffmpeg_reader.py", line 243, in ffmpeg_parse_infos&#xA;is_GIF = filename.endswith(&#x27;.gif&#x27;)&#xA;AttributeError: &#x27;_io.BytesIO&#x27; object has no attribute &#x27;endswith&#x27;&#xA;</path></path></path></module></stdin>

• nginx ffmpeg mpegts http

  6 mars 2024, par michel

  i can't understand how to serve .ts files from nginx.
for hls it works without problems (m3u8).

  



  http://127.0.0.1/hls/stream_name.m3u8

  



  http://127.0.0.1/stream_name

  



  I tried to compile nginx with the 2 modules :

  



  nginx-live-module

  



  nginx-ts-module

  



  It works in part, if I send a stream it works, if I send for example 10 it doesn't work.

  



  ffmpeg -re -f concat -safe 0 -i stream.txt -c copy -map 0 -f mpegts "http://127.0.0.1/stream_name?buffer_size=1048576"

  



  with VLC I open the stream and it works but if I try to open more streams it doesn't open even if ffmpeg is sending to the nginx server.

  



  what am I doing wrong ?
