  9 janvier 2019, par Lus

  I want to use Ffmpeg to pull&push video stream from HLS to RTMP.at first it’s normal,but when I open more,it’s run normally ,but no video data pull&push

  Environment：Windows64+Ngg-§rtmp-static+Ffmpeg-static+Java1.8

  It’s useless,even if I restart rtmp-server.

  ffmpeg -i xxx/live.m3u8 -vcodec h264-s 720*480 -an -f flv -y rtmp://xxx

  The first few video streams is normal,but when I open more streams (5+),
  it run normally,but no data pull.like this.

• Android : Show quick preview (live) before exporting FFmpeg Video

  1er mai 2023, par akash varlani

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

  



  I am using FFMPEG to generate video slide show from images but the problem is I can only show the 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 the 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 the video. This app displays instant preview once I change the image.

  



  

  



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

  



  Clicking an EXPORT button this app lets you generate a 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 a quick preview of OUTPUT VIDEO before generating actual VIDEO FILE.

  



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

  



  Some useful link :

• Show Filename in Video ffmpeg batch script

  19 mars 2019, par Oli Shingfield

  I have a folder with around 10 different mov files. I would like to add the filename as text on each of the videos using ffmpeg in a bat file. Could someone help me achieve this please ?

  EDIT :

  I have tried using

  @ECHO OFF&Setlocal EnableDelayedExpansion
  
  Set INPUT=E:\\Users\\Oli\\Documents\\Projects\\v1.3.0\\downloads3
  
  Set OUTPUT=E:\\Users\\Oli\\Documents\\Projects\\v1.3.0\\downloads3
  
  for %%a in ("%INPUT%\*.*") DO ( 
  
      set "filename=%%~na"
  
      ffmpeg -i "%%a" -vf "drawtext=text=!fileName:.= !:x=105:y=120:fontfile=E:\\Users\\Oli\\Documents\\Projects\\v1.3.0\\downloads3\\impact.ttf:fontsize=25:fontcolor=white" -b:v 1M -r 60 -b:a 320k -ar 48000 -crf 17 "%%~na.mov"
  
  )`

  But it gives me the error :

   Cannot find a valid font for the family Sans
  
  [AVFilterGraph @ 0000026eb75a9f40] Error initializing filter 'drawtext' with args 'text=FileName1'
