  • ffmpeg watermarking processing is very slow

    25 février 2014, par Hitesh Rohilla

    I am working on a video processing project and using ffmpeg for watermarking. I achieve exactly what i want but the problem is that the process is very very slow.

    I am using a Intel Smart 2nd gen family Core-i5 Processor with 4GB RAM on a 32 bit operating system Microsoft Windows-8 on a 64-bit CPU.

    I tried watermarking a video [mp4] of length 1:30 Min. size of file is 1.5GB

    Whole process accomplish in 3 Hrs to watermark my video file and what i noticed while process is that ffmpeg was processing 28 frames per sec first and then later it slow down up to 20 frames per second. a normal human watch video with frame rate of 30 frame per second and process was even slower then this that's why it took more time [3 Hrs] then the actual length of video itself [1:33]

    What i think to make process efficient is to use ffmpeg Watermarking Source Code and modify it somewhat...

    I want to ask if someone have achieve fast watermarking before by any other way or have modified this code to achieve faster process in order to save my time...

  • avfilter/vf_libplacebo : correctly update SAR to reflect scaled result

    avfilter/vf_libplacebo : correctly update SAR to reflect scaled result

    This aligns the behavior of vf_libplacebo with other filters in the
    
vf_scale family, that forward any change in the SAR as a result of
    
changing the output resolution to the output frame / link, and updates
    
the ff_scale_adjust_dimensions() call to continue working as intended.
    

    The new behavior reflects the documentation of vf_libplacebo, which
    
described this behavior despite that not being the way the filter worked
    
up to this point.
    

    As an aside, also fixes a bug where the AVFrame SAR was inconsistent
    
with the AVFilterLink SAR when the s->nb_inputs > 1 condition was met.
