  Calling ffmpeg from Java throws "Trailing garbage after a filter" Error

  


  I tried to call from Java application command string over dockerized ffmpeg, same result.

  


  docker run --rm  -v sample-test:/config linuxserver/ffmpeg  -loop 1 -t 5 -i  config/1.jpeg  -loop 1 -t 5 -i  config/3.jpeg  -y -filter_complex "[0:v]fade=t=out:st=4:d=1[v0];  [1:v]fade=t=in:st=0:d=1,fade=t=out:st=4:d=1[v1];  [v0][v1]concat=n=2:v=1:a=0,format=yuv420p[v];" -map "[v]"  config/output/video_java.mp4


  


  My goal is to run such a query from Java application

Runtime.getRuntime().exec(String.format("/bin/sh -c " + ffmpegCommand));

• Piwik 2 reaches end of life soon (December 2017), update now !

  7 décembre 2017, par Piwik Core Team — Community

  In less than three weeks, Piwik 2 will be no longer supported. This means that no further (security) updates will be released for this version. As per our Long Term Support announcement, Piwik 2.X is supported for 12 months after the initial release of Piwik 3.0.0 which was on December 18th 2016. Therefore, Piwik 2 will no longer receive any updates after December 18th 2017.

  It has been almost a year since we released Piwik 3 and we highly recommend updating to Piwik 3 ASAP. The major new release came with a new UI, performance and security improvements. If you are still on Piwik 2, the security improvements alone should be worth updating your Piwik to Piwik 3 now. We cannot recommend this enough.

  The update to Piwik 3 should be smooth, but may take a while depending on the amount of data you have.

  • If you have any problem with the update, feel free to get in touch with us, or ask in the forums.
  • If you are currently using Piwik self-hosted and would like to be upgraded, plus your Piwik managed in the official Cloud-hosted service, contact InnoCraft Cloud and they will migrate your database.

  At Piwik and InnoCraft, the company of the makers of Piwik, we have seen many thousands of Piwik installations upgraded over the past year and look forward to an exciting future for Piwik 3 and beyond !

• Will the encoded YUV color be the same as the decoded color on ffmpeg ?

  27 juillet 2020, par Guerlando OCs

  If I have an h264 video encoded in the color format YUV444 and I decode it with ffmpeg (can be software or hardware decoding), then will the decoded image be in the format YUV444 ?
