    31 janvier 2020, par Krishnakumar

    I am seeing the following scrambled output for a live stream when processing an udp input stream. I am using the recently downloaded ffmpeg from GIT. Stop and Start of ffmpeg command resolves the issues temporarily.

  • ffmpeg unique frames only

    5 novembre 2013, par William

    I have a video sequence (MPEG1) of 30 fps that is decoded in two ways :

    • opencv_ffmpeg returns 30 images per second, but only 5 of them are unique, while all others are clones of the unique ones.

    • proprietary players (MediaPlayer) returns only the 5 unique frames and "holds" them for (1/5) sec each.

    Is there a way to grab only the unique frames that the coder knows and not the total amount the ffmpeg decoder produces to fulfill the fps rate ?

    I'm developing a tracker and my tracker is forced to run 6 times slower and do many mistakes due to these "cloned frames".

    Does anyone know any technical term to the problem ? Unfortunately, ffmpeg is a black box for an opencv user and the documentation is sparse.
