  • use java-ffmpeg wrapper, or simply use java runtime to execute ffmpeg ?

    12 mars 2017, par user156153

    I’m pretty new to Java, need to write a program that listen to video conversion instructions and convert the video once an new instruction arrives (instructions is stored in Amazon SQS, but it’s irrelevant to my question)

    I’m facing a choice, either use Java RunTime to exec ’ffmpeg’ conversion (like from command line), or I can use a ffmpeg wrapper written inJava http://fmj-sf.net/ffmpeg-java/getting_started.php

    I’d much prefer using Java Runtime to exec ffmpeg directly, and avoid using java-ffmpeg wrapper as I have to learn the library. so my question is are there any benefits using java-ffmpeg wrapper over exec ffmpeg directly using Runtime ? I don’t need ffmpeg to play videos, just convert videos

    Thanks

  • AWS Rekognition error : Chunk video failed

    14 juin 2022, par Stefano Leone

    I'm using and launching Amazon Rekognition on my videos uploaded into my S3 with python. Every video is converted with FFMPEG with AAC Audio Codec and H264 Video Codec and then given to Rekognition. Videos are always fine, the problem is that only 60-70% of videos are processed successfully, while the rest of videos goes into error. In particular, inside the JSON returned from Rekognition :

    


    {&#x27;JobId&#x27;: &#x27;<id of="of" my="my" job="job">&#x27;, &#x27;Status&#x27;: &#x27;FAILED&#x27;, &#x27;API&#x27;: &#x27;StartFaceDetection&#x27;, &#x27;Message&#x27;: &#x27;Chunk video failed: Only 1 I-frames found in video&#x27;, &#x27;Timestamp&#x27;: 1655118632996, &#x27;Video&#x27;: {&#x27;S3ObjectName&#x27;: &#x27;<my video="video" inside="inside" s3="s3">&#x27;, &#x27;S3Bucket&#x27;: &#x27;<my s3="s3">&#x27;}, &#x27;ErrorCode&#x27;: &#x27;VideoNotDecodable&#x27;}&#xA;</my></my></id>

    &#xA;

    As you can see, I get an error "Chunk video failed: only 1 I-Frames found in video". Honestly I don't know what is that, but the fact that I convert every video in the same way, but Rekognition fails only with some, makes me crazy. Googling was not helpful, hope you can tell me what's wrong.

  • rails streamio-ffmpeg does not find uploaded video files

    26 avril 2016, par Felix

    I try to make a screenshot as thumbnail of a movie while uploading.

    My code looks like this at the moment

    require 'rubygems'
    
require 'streamio-ffmpeg'
    

    
 def uploadMovie
    
   @channels = Channel.all
    
   @vid = Movie.new(movies_params)
    

    
   @channel = Channel.find(params[:vid][:channel_id])
    
   @vid.channel = @channel
    

    
   if @vid.save
    
     flash[:notice] = t("flash.saved")
    
     movieFile = FFMPEG::Movie.new(@vid.video.to_s)
    
     screenshot = movieFile.screenshot("uploads/screenshot", :seek_time => 10)
    
     render :add
    
   else
    
     render :add
    
   end
    
 end

    But when I do this I got this error :

      No such file or directory - the file 'http://.s3.amazonaws.com/uploads/movie/video/7/2016-04-24_16.26.10.mp4' does not exist

    That should be okay because I upload the movies to Amazon S3 with carrierwave ...

    What’s going wrong in this case ?
