• FFMPEG Steam Stream stop after a few min

  24 novembre 2022, par Fabian Boulegue

  I try set a video stream to STREAM via FFMPEG so far everything works fine but after a few min it just seem to timeout (at last the stream stops but ffmpeg still send everything)

  



  Here is the ffmpeg string

  



  OUTRES="1920x1080"
GOP="60"
GOPMIN="15"
THREADS="4"
CBR="2500k"
QUALITY="ultrafast"
VIDEO="rescue.mp4"
STREAM_KEY="steam_62879128_f5xxxxxxxca5b1c"
SERVER="rtmp://ingest-01-fra1.broadcast.steamcontent.com/app/"

  this is the ffmpeg output

• FFMPEG image to video showing blank video

  18 avril 2017, par Ravi Rupareliya

  Here is my command to create a video from multiple images.

  File f = new File(Environment.getExternalStorageDirectory() + "/abc.mp4");
  
  
  
  try {
  
      f.createNewFile();
  
      ffmpeg.execute(new String[]{"-y","-r","1/5","-i","" + "/" + "image%01d.jpg","-pix_fmt","yuv420p","-c:v","libx264","-crf","23","-s","640x480",f.getPath()}, listener);
  
  } catch (Exception e) {
  
      e.printStackTrace();
  
  }

  I have multiple images available at with having names like image1.jpg, image2.jpg etc etc.

  It is creating video file with some 100-200 KB but it showing blank images in VLC player.

  When i try to run it with Windows Media Player, it only runs if it is in repeat mode from player, otherwise it is not playing.

  Output in onSuccess()

• Multiple format changes in FFmpeg for thermal camera

  6 février 2023, par Greynol4

  I'm having trouble generating a command to process output from a uvc thermal camera's raw data so that it can be colorized and then output to a virtual device with the intention of streaming it over rtsp. This is on a raspberry pi 3B+ with 32bit bullseye.

  


  The original code that works perfectly for previewing it is :

  


  ffmpeg -input_format yuyv422 -video_size 256x384 -i /dev/video0 -vf 'crop=h=(ih/2):y=(ih/2)' -pix_fmt yuyv422 -f rawvideo - | ffplay -pixel_format gray16le -video_size 256x192 -f rawvideo -i - -vf 'normalize=smoothing=10, format=pix_fmts=rgb48, pseudocolor=p=inferno'


  


  Essentially what this is doing is taking the raw data, cutting the useful portion out, then piping it to ffplay where it is seen as 16bit grayscale (in this case gray16le), then it is normalized, formatted to 48 bit rgb and then a pseudocolor filter is applied.

  


  I haven't been able to get this to translate into ffmpeg-only because it throws codec errors or format errors or converts the 16bit to 10bit even though I need the 16bit. I have tried using v4l2loopback and two instances of ffmpeg in separate windows to see if I could figure out where the error was actually occuring but I suspect that is introducing more format issues that are distracting from the original problem. The closest I have been able to get is

  


  ffmpeg -input_format yuyv422 -video_size 256x384 -i /dev/video0 -vf 'crop=h=(ih/2):y=(ih/2)' -pix_fmt yuyv422 -f rawvideo /dev/video3

  


  Followed by

  


  ffmpeg -video_size 256x192 -i /dev/video3  -f rawvideo -pix_fmt gray16le -vf 'normalize=smoothing=10,format=pix_fmts=rgb48, pseudocolor=p=inferno' -f rawvideo -f v4l2 /dev/video4

  


  This results in a non colorized but somewhat useful image with certain temperatures showing as missing pixels as opposed to the command with ffplay where it shows a properly colorized stream without missing pixels.

  


  I'll include my configuration and log from the preview command but the log doesn't show errors unless I try to modify parameters and presumably mess up the syntax.

  


   ffmpeg -input_format yuyv422 -video_size 256x384 -i /dev/video0 -vf 'crop=h=(ih/2):y=(ih/2)' -pix_fmt yuyv422 -f rawvideo - | ffplay -pixel_format gray16le -video_size 256x192 -f rawvideo -i - -vf 'normalize=smoothing=10, format=pix_fmts=rgb48, pseudocolor=p=inferno'

  I'd also like to use the correct option so it isn't scrolling though every frame in the log as well as links to resources for adapting a command to a script for beginners even though that's outside the purview of this question so any direction on those would be much appreciated.
