• How to bookmark a video, to skip the video to a cetain duration ?

  17 août 2016, par Prasanth Kumar Arisetti

  I am encoding the incoming camera data, using x264 encoder and mpegtsmux to a filesink .ts files.

  I am pushing the buffers to the pipeline, using, g_signal_emi_by_name.

  Pipeline is something like this :

  gst-launch-1.0 v4l2src ! videoconvert ! video/x-raw,width=720,height=576,framerate=25/1 ! x264enc ! mpegtsmux ! filesink  location=test.ts

  Now, for that video, i would like to add bookmarks for certain duration to directly skip the video to that duration, when click on that duration.

  How can i add bookmarks to that video ?

  I have a 10 min video file(.ts file), it has the gaps(empty video) from 4th min to 7th min. I want to insert the static frames from start of the gaps to end of the gap.

  


  I have a command to create the static video with null(silent) audio.

  I want to add this static video with silent audio in a a recording from specific period.

  


  How can I achieve it ?
