  • Revision 5daef90efc : skip un-neccessary motion search in the first pass This patch allows the encode

    4 juin 2014, par Pengchong Jin

    Changed Paths :

    skip un-neccessary motion search in the first pass

    This patch allows the encoder to skip the
    un-neccessary motion search in the first pass. It
    calculates the error of the zero motion vector using
    the last source frame as reference and skips the
    further motion search in the first pass if the error
    is small.

    The encoding speedup of the first pass for slideshow
    videos is over 30%. Borg test shows the overall PSNR
    performance remain approximately the same (derf -0.009,
    hd 0.387, yt 0.021, stdhd 0.065). Individual clips may
    have either PSNR gain or loss. The worst PSNR perfomance
    is from yt set, with a PSNR loss of -1.1.

  • How do I use ffmpeg on a directory of files and have the new files retain the same name, using Bash ? [duplicate]

    31 janvier 2021, par ktb

    hopefully this will be a relatively straightforward question.

    


    I have a directory of files. The files are mkv files that contain .vtt subtitles. I want to change the vtt subtitles into .srt subtitles. Ideally the mkv files should retain the same names at the end of the process.

    


    I have this Bash command that uses ffmpeg :

    


    ffmpeg -i input.mkv -c copy -c:s srt out.mkv


    


    This command works on an individual file, in terms of giving me a new file with the correct srt subtitles muxed in.

    


    However it does not :

    


      

    • let me wildcard the mkv file (I have to specify the input.mkv file)

      • 


    • let me keep the name of the original mkv file

      • 


    


    Could someone help please ? I'm thinking it would be a relatively simple Bash loop (for x in *.mkv...) but any help would be most gratefully received. I really want the output files to have the same name as the input files at the end of the process. Thank you.

    


  • avformat/mov : Enable stream parsing for VP9.

    avformat/mov : Enable stream parsing for VP9.

    MP4 media containing VP9 using superframes (such as
    
https://github.com/Netflix/vp9-dash/raw/master/DASH-Samples/Fountain_2997_0560kbps_640x480_4x3PAR.ivf_DashUnencrypted.ismv)
    
does not decode correctly with the built-in VP9 decoder because
    
superframes are passed to the decoder whole rather than split into
    
individual frames.
