  I am experimenting with live streaming my Windows 7 desktop to YouTube.

  


  Firstly the list of devices :

  In short the errors are :

  I have tried with and without the :1935 port number, with ffmpeg_x64.exe but no difference. Is the stream key the invalid argument or something else ?

  


• FFMPEG in an AWS Lambda will only output 5 seconds of converted video [duplicate]

  5 juin 2021, par beerandsmiles

  I've been looking for a solution for this issue, but I can't seem to find what's going wrong.

  


  In short, I'm using an AWS Lambda to convert video captured from an raspberry pi in a raw .h264 format to .mp4. The problem is that the output file is always, only 5 seconds long.

  


  So I input a video of say 500mb, that is 10 minutes long, and the output is an mp4 that is exactly the first 5 seconds of the source video.

  


  The lambda has been setup following the tutorial from Amazon that is shown here :
https://aws.amazon.com/blogs/media/processing-user-generated-content-using-aws-lambda-and-ffmpeg/

  


  It is triggered by an upload from one s3 buckets, transcodes, and puts it in a different bucket. The purpose is to store a high quality copy of the video that is smaller to save costs. (this is a personal project, so I'm paying personally)

  


  I've put the full code of the lambda down below.
I had trouble using their recommended stdout method as that resulted in a file being created with a size of 0 bytes.

  


  You'll see a few commented lines where I tried different things to solve it. I thought it best to leave that in while asking the questions so you can see what I've done. Firstly the method of using stdout piped directly into the output S3 did not work, so I stored the output file in lambda's /tmp directory.

  


  However, when I first did this using the signed link as the input it gave me 5 seconds of the input video.

  


  Thinking this had to do with an issue in the stream that FFMPEG was getting, I tried instead to download the file from the first S3 bucket into the temp folder, then convert it, and then upload it.

  


  The actual FFMPEG command is quite simple

  


  f"/opt/bin/ffmpeg -framerate 25 -i {s3_source_key} output.mp4"

  


  But this outputs a 5 second video.

  


  I have also tried using different versions of FFMPEG for the layer with lambda and no help. Also, I have set and execution timeout of 2 minutes with 2gb or ram for this lambda.

  


  The last thing, is that running this command on a linux machine, such as a raspberry pi directly, results in an mp4 of the correct length, only in the lambda am I having this problem.

  


  I'm completely lost, and I can't seem to find any documentation on this happening to anyone else.

• FFMPEG Inverts colors when converting tiff pictures to png

  1er juin 2021, par Mounia Jaiti

  We need to convert thousands of tiff pictures to png. To accomplish that we are using FFMPEG. We've noticed recently that for very few of the converted files (in png), the colors are inverted : the input tiff file is all black and white (a technical drawing in black with a white background), and the output png file is white and black (the drawing becomes white and the background becomes black). Of course we don't want that, we need the colors to stay the same.

  


  Here is the command we are using :

  


  ffmpeg -y -v warning -i in_file.tif out_file.png


  


  We've tested the 'negate' parameter on those files, and the pictures are correctly converted. But we can't apply this parameter to all of the input tiff files.
Here is the command with the negate parameter :

  


  ffmpeg -y -v verbose -i input.tif -vf negate output.png


  


  The Code Java we're using :

  


              String ffmpegPath="/Users/user11/ffmpeg//ffmpeg";&#xA;            List<string> commandArgs = new ArrayList<string>();&#xA;            commandArgs.add(ffmpegPath);&#xA;            //overwrite output file if it exists&#xA;            commandArgs.add("-y");      &#xA;            commandArgs.add("-v");&#xA;            commandArgs.add("verbose");&#xA;            //set input file &#xA;            commandArgs.add("-i"); &#xA;            commandArgs.add(picture.getAbsolutePath());&#xA;            commandArgs.add(dest.getAbsolutePath());&#xA;            &#xA;            String cmd = "";&#xA;            for(String cmdArg : commandArgs) {&#xA;                cmd &#x2B;= cmdArg &#x2B; " ";&#xA;            }&#xA;&#xA;&#xA;</string></string>

  So our questions are :

  


  

  1. Is there a way to identify the tiff files that will be converted to png with inverted colors ? So that we can know to which files the 'negate' parameter must be applied.

  


  2. Are there any other FFMPEG parameter that we can use.

  


  


  This issue has been driving us mad for the last couple of days. Any help would be highly appreciated.
Thanks.
