  • How can I use FFMPEG to fix a mpeg.ts file

    29 septembre 2017, par Tim McClure

    I have an mpegts file that has some minor quality issues. Can I use ffmpeg to create an mp4 file from it and the mp4 file plays fine - meaning the transmuxing to mp4 corrected the problem. I am trying to use ffmpeg to re-encode the mpegts file to another mpegts file and through the transmuxing have the video file fixed. The script I am using :

    ffmpeg -re -i 20170925T214300_S051-0001.ts -pix_fmt yuv420p -vcodec libx264 -r 25 -vf "scale=1024:576" -threads 0 -b:v: 2048k -bufsize 2244k -maxrate 2560k -profile:v baseline -g 50 -x264opts no-scenecut -x264opts force-cfr -an -f mpegts mcclure.ts

    Is what I am trying to do possible ?

  • FFmpeg : how to make video out of slides and audio

    17 juillet 2014, par Muhammad Umer

    So i have several images some png and some jpgs. And i have mp3 audio. I want to make a video file don’t care what format.

    So i want either :

    A video made up of xyz size meaning images are centered and cropped if they go beyond dimensions coupled with audio in mp3 format..

    or just one image centered or and cropped, still image, video with audio.

    I have tried copying and pasting things and even modifying them after reading documents but in the end i got a blank video with audio and huge file that took forever to complete.

    I have windows 7.

  • ffmpeg - scrolling text with specified boundaries and cut video when text ends

    19 février 2017, par Elma Paul

    Having this working ffmpeg filter with overlayed scrolling text 

    f -i text_bg.mp4 -vf "drawtext=enable:fontsize=200:fontcolor=White:fontfile='ARIALN.TTF':text='asdfhlajsdh LKFJAHSDFH':x=-(mod(8*n\,w+tw)-tw):y=h/2-th/2" outtt.mp4 -y

    I have two questions :
    1.) How can I set specified boundaries for drawtext ? Just fix positions where the text will dissapear. Like here in picture
    scrolling text with specified boundaries example
    2.) How is it possible to cut the video(specify time) according to the text length.Meaning that the video will finish after ends the text line +plus one second ?
