• ErrorCode 1 while merging 2 videos

  10 janvier 2023, par Stéphane de Luca

  I am trying to merge two videos but have an error code 1.

  


  My command is as follows :

  


    final command =
        '-y $commandPaths -filter_complex \'[0:0][1:0]concat=n=${paths.length}:v=1:a=0[out]\' -map \'[out]\' $outputPath';


  


  I see the following error :

  


  


  I/flutter (17343) : Stream specifier ':0' in filtergraph description [0:0][1:0]concat=n=2:v=1:a=0[out] matches no streams.

  


  


  Not easy to understand what caused this as I am not familiar with the lib.

  


  I saw in a so that someone had the issue caused by the tw videos not having the same size.

  


  The logs are as follows :

• Send updating image to rtmp with ffmpeg in flutter app

  19 janvier 2023, par un_cafeinoman

  I have a JPG image in a directory that I update each time I got a new one and I have to send this image to a rtmp server.
I fond that ffmpeg can do that but I thougt -loop 0 is suppose to loop over the image and see if it is refreshed but when I start my command inside my app it seem to start well and end with good Return Code (0) but don't seem to loop.

  


  Here is my ffmpeg command : '-re -loop 0 -i $pathToFile -preset ultrafast -tune zerolatency -c:v libx264 -f flv $streamUrl'

  


  This code execute the command :

  


       FFmpegKit.executeAsync(command, (session) async {

        if (ReturnCode.isSuccess(await session.getReturnCode())) {

          log('FFmpeg process exited with rc ${await session.getReturnCode()} in ${await session.getDuration()} milliseconds');

        } else if (ReturnCode.isCancel(await session.getReturnCode())) {

          log('FFmpeg process cancelled');

        } else {

          log('FFmpeg process failed with rc ${await session.getReturnCode()} in ${await session.getReturnCode()} milliseconds');

        }
      }, (session) {

        log('Message ${session.getMessage()}');

      }, (session) {

        log('Statistics ${session.toString()}');

      });


  


  And finally I got those logs :

  All of this in inside a Flutter app with the package ffmpeg_kit_flutter (the full gpl version of it).

  


  Any one have an idea of how to loop over constantly every time the image is updated ?

  


  Edit : I try adding -f image2 in input but it failed with :

• FFmpeg pseudocolor filter - Option 'p' not found Error initializing filter 'pseudocolor' with args 'p=inferno'

  I'm trying to process output from a uvc camera using ffmpeg. The original command that I was given that works on another linux distribution 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'

  


  (yes it works on his machine, I've seen the screen capture)

  


  I can get everything but the pseudocolor filter to work and this command works fine if i just delete , pseudocolor=p=inferno

  


  This is for processing the stream from a thermal camera that outputs raw data as video which necessitates the cropping and processing and is also why the resolution is so low.

  


  No matter what I do, it throws - Option 'p' not found Error initializing filter 'pseudocolor' with args 'p=inferno' \[rawvideo @ 0x625007a0\] Packet corrupt (stream = 0, dts = 3).=0/0 
I have modified it for my needs but I still cant get the pseudocolor filter to use the presets.

  


  The full configuration and output are below. This is a raspberry pi 3B+ running bullseye that I've reinstalled multiple times without resolution of this problem.

  The examples for the presets in the documentation are lacking but that makes me think that it shouldn't be giving this much trouble and I'm overlooking something.

  


  I plan on integrating this but can't until I can proceed with this proof of concept.

  


  Thanks for any help !
