• ffmpeg exited with code 1 : Error reinitializing filters ! Failed to inject frame into filter network : Invalid argument

  15 juin 2022, par ijaz khan

  Using video show npm I am creating a video from multiple images. initially there was an issue but then I download and installed ffmpeg.

  


  Now another error occurs. Thanks to everyone in advance.

  


  This is my code :

  


  //create a video from multiple images 

var secondsToShowEachImage = 3
var finalVideoPath = '/outputImages/newvideo2.mp4'

// setup videoshow options
var videoOptions = {
  fps: 24,
  transition: false,
  videoBitrate: 1024 ,
  videoCodec: 'libx264', 
  size: '640x640',
  outputOptions: ['-pix_fmt yuv420p'],
  format: 'mp4' 
}
let path1= '/InputImages/abc.jpg';
let path2 = '/InputImages/xy.jpg'
let path3 = '/InputImages/ab.jpg'

// array of images to make the 'videoshow' from
var images = [
  {path: path1, loop: secondsToShowEachImage}, 
  {path: path2, loop: secondsToShowEachImage}
]
console.log('working --->')
 videoshow(images, videoOptions)
.save(finalVideoPath)
// console.log('hello world')
.on('start', function (command) { 

  console.log('encoding ' + finalVideoPath + ' with command ' + command) 
})
.on('error', function (err) {
   console.log('err' , err)
//   return Promise.reject(new Error(err)) 
})
.on('end', function (output) {
  // do stuff here when done
})


  


  The error is

  


  err Error: ffmpeg exited with code 1: Error reinitializing filters!&#xA;Failed to inject frame into filter network: Invalid argument&#xA;Error while processing the decoded data for stream #1:0&#xA;Conversion failed!&#xA;&#xA;    at ChildProcess.<anonymous> (E:\Video-Editor-Practice\Nodees6video-editor\NewVideoEditor\node_modules\fluent-ffmpeg\lib\processor.js:182:22)&#xA;</anonymous>

  


• How to set normal speed of playback after capturing and transcoding stream video by `ffmpeg_streaming` in Python project ?

  30 avril 2020, par Harley Club

  Using ffmpeg_streaming module in Python project with Flask, I try to set up video streaming from online camera into local file. My purpose is receiving input stream that comes as HLS-compatible data. To implement this property, I've inserted some code accessible by this link :

  



  import ffmpeg_streaming
from ffmpeg_streaming import Formats, Bitrate, Representation, Size

from flask import render_template, Flask, send_from_directory, abort, json, Response  

import sys

app = Flask(__name__)

video = ffmpeg_streaming.input('http://wmccpinetop.axiscam.net/mjpg/video.mjpg')

_480p = Representation(Size(854, 480), Bitrate(750 * 1024, 192 * 1024))
hls_stream = video.hls(Formats.h264(), hls_list_size = 10, hls_time = 5)
hls_stream.representations(_480p)
hls_stream.output('/var/media/hls_outputs.m3u8')


  



  It works as expected, i.e. video stream gets written into local file, then I can see what camera shot somewhere far from there...But an only problem arises here which I can't manage : once playback starts, the video is being displayed utterly fast. Nearly 2 minutes period covered by camera (I can see how long real time was over due to camera-embedded timer option) has duration of 5 seconds when playing back. So, how do I want to enable video speed just as it fits into real-world timing ? My OS is Ubuntu 18.04 LTS and I open file with preinstalled Videos app to watch content.

  


• Why can I not change the number of frames (nframes) in a gganimate animation ? SOLVED

  26 décembre 2022, par Gekin

  I have produced an animation per gganimate and rendered it per ffmpeg. It works just fine, but only, if I do not change the number of frames. If I do set the number of frames, I get this error message :

  


  nframes and fps adjusted to match transition
Error parsing framerate 8,4.                           
Error: Rendering with ffmpeg failed


  


  I produced the gganim MonthlyAveragePrecipitationMap the following way :

  


  options(scipen = 999, OutDec  =  ",")

MonthlyAveragePrecipitationMap = ggplot(MonthlyAverageExtremePrecipitation) + 
  geom_path(data = map_data("world","Germany"),
            aes(x = long, y = lat, group = group)) +
  coord_fixed(xlim = c(6,15),
              ylim = c(47,55)) + 
  geom_point(aes(x=lon, y=lat, 
                 colour = ShareOfExtremePrecipitationEvents,
                 group = MonthOfYear),
             size = 3) + 
  scale_color_gradient(low="blue", high="yellow") + 
  xlab("Longitude (degree)") +
  ylab("Latitude (degree)") + 
  theme_bw() +
  transition_manual(frames = MonthOfYear) + 
  labs(title = '{unique(MonthlyAverageExtremePrecipitation$MonthOfYear)[as.integer(frame)]}', 
       color = paste0("Share of Extreme Precipitation Events \namong all Precipitation Events")) 


  


  I call the animation the following way :

  


  animate(MonthlyAveragePrecipitationMap,
        nframes = 300,
        renderer =
          ffmpeg_renderer(
            format = "auto",
            ffmpeg = NULL,
            options = list(pix_fmt = "yuv420p")))



  


  I used this exact code just a few days ago and it worked fine.

  


  Has someone had similar experiences ?
Thanks in advance.

  


  EDIT : Problem solved.

  


  

  • Problem : Changing the decimal seperator from . to , per options(dec=",")

  


  • Solution : Changing the decimal seperator locally within the axis scaling per function.
