• Is ffmpeg a good upscaler from SD to HD ?

  Is ffmpeg a good upscaler to convert SD videos to HD ?

  I use the AVANTI GUI. I installed it and put the ffmpeg and ffplay exe into the folder ffmpeg in the program folder. What I know is that you can only preserve the detail when you upscale from SD to HD. You don’t really gain any additional information. TV companies like Samsung, Sony, LG, Panasonic, Sharp, and others refuse to think so and push the boundaries of upscaling so that additional information can be added when the image is upscaled from SD to HD and HD to 4K and so on and so forth. I’ve run a test through the AVANTI ffmpeg GUI.

  Codec : XVID to H.264
  Bitrate : 1640 kbps to 6000 kbps
  Resolution : 640x480 to 1440x1080
  Format : AVI to M4V
  Audio Codec : AC3 to AAC
  Audio Bitrate : 192 kbps
  Audio Frequency : 48000 Hz
  Upscale method : Spline

  Will this upscale method work in any way with converting SD video to HD video. There’s a lot of SD content out that haven’t made the transition to, or probably never will be, HD.

• Java, FfMPEG : Gson not found even though it's there.

  19 avril 2018, par We are Borg

  I am working on a Spring-MVC application in which we are using FFProbe to get media information. Unfortunately, it’s not working on our live instance. We have ffmpeg & ffprobe installed on same path. The error we get is GSON is not foudn, although we have it.

  Error log :

  Usage :

  Error thrown on first line.
  
  FFprobe ffprobe = new FFprobe("/usr/bin/ffprobe");
  
  FFmpegProbeResult probeResult = ffprobe.probe(filePath);

  I can confirm that ffprobe file is available on /usr/bin. What am I doing wrong here ? Thank you.
