• Creating a thumbnail from MP4 video crashes on shared hosting but working fine locally

  15 juillet 2019, par Mariam Nagy

  i am working on a web page to upload MP4 video and getting a thumbnail from the video

  i am using NReco FFMpeg Converter to achieve this . it is working fine locally but upload it on a shared hosting it crashes at ffMpeg.GetVideoThumbnail

          string VideoUrl = dataMediaUrl.ImageUrl;
  
          string extension = VideoUrl.Split('.')[VideoUrl.Split('.').Length - 1];
  
          var ffMpeg = new NReco.VideoConverter.FFMpegConverter();
  
          string thumbnailJPEGpath = Server.MapPath(VideoUrl.Replace("~/upload/MediaGallery/", "~/upload/MediaGallery/Thumb_").Replace("." + extension, ".jpg"));
  
          ffMpeg.GetVideoThumbnail(Server.MapPath(VideoUrl), thumbnailJPEGpath);
  
          dataThumbUrl.ImageUrl = VideoUrl.Replace("~/upload/MediaGallery/", "~/upload/MediaGallery/Thumb_").Replace("." + extension, ".jpg");

  This is the error I am getting :

• FFmpeg Time Lapse from Sources with Long Frozen Tail End

  5 juillet 2019, par Rich_F

  My source for inputs into FFmpeg is either one AVI file or a concat of many of them. Either way my resulting timelapse file has a long tail of frames that are a repeat of a single frame. It’s like a very long freeze frame is resulting on the end of my output file.

  I’m on an older Mac Pro so I can’t update my FFmpeg. I have a laptop that has a newer version and I get the same there as well. I’m not sure if it’s because my source files are AVI or not.

  Am I overlooking something ? I’m trying to speed up the inputs into a single file to quickly review incoming security footage. How can I do this without the super long useless tail at the end ?

• Alfresco fails to create video thumbnail

  17 octobre 2019, par Deckard

  As error log says : Empty input file ... It turned out that the source image for ImageMagick is zero sized. (/data/was/alfresco/tomcat/temp/Alfresco/ImageMagickContentTransformerWorker_source_8718262212685093199.jpg). When I manually replace the source image to normal image and execute the command again, there’s no error.

  command:    /data/was/alfresco/common/bin/convert /data/was/alfresco/tomcat/temp/Alfresco/ImageMagickContentTransformerWorker_source_8718262212685093199.jpg[0] -auto-orient -resize "100x100>" -strip -quiet /data/was/alfresco/tomcat/temp/Alfresco/ImageMagickContentTransformerWorker_target_7652060684136589026.png

  So I think the source image is maybe made by FFMPEG by capturing some frame of the video.
  And the FFMPEG somehow failed to do it. Not sure my guess is right...

  But my FFMPEG works good as ffmpeg -version shows proper version info. And FFMPEG is run by root and the Alfresco daemon instance is run by root. It seems that there’s nothing wrong.

  Please review it. Here’s the whole Alfresco-share log :

  But the log is too long to paste here. There’s 30,000 characters limit of body in SO which github doesn’t have.
