  • Learning Shell - creating a script with parameters that runs two separate cli apps

    16 mai 2013, par GuilhermeNagatomo

    I want to learn shell script, so I'm trying to download a youtube video using youtube-dl then convert it to mp3 using ffmpeg.

    I do it manually running youtube-dl http://youtube.com/watch?v=...
    then
    ffmpeg -i downloadedFile -ab 256000 -ar 44100 audioFile.mp3.

    I know that I need to pass two arguments to my script, one for the video url and another for the audio file to keep things as simple as possible, but I don't know how to start. Maybe grep the video id in the url and using it to know which file to use to convert into mp3 ? (since youtube-dl saves the video named by it's id)

    Can someone recommend me an article or documentation that can help me ?

  • 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...

  • changing frame-rate for .mov

    5 juin 2013, par Ryan Saxe

    So I have a script in python that uses urllib to download a bunch of images and I then use ImageMagick to add labels to the images and then throw them into a MOV file.

    My issue is that the MOV file is going at 30 frames per second, and that is way too fast for me to be able to watch what is happening. I need something that is more like 5-10 frames per second.

    Is there a way to do this in ImageMagick, FFmpeg or any other easily accessible and cross platform package ?

    EDIT 1 : showing my ImageMagick

    convert -quality 100 *.png my_movie.mov

    I wasn't able to find it, but is there some line I add like -frameRate or something like that to allow me to choose the frame rate ? I can also use FFmpeg along with it so if anybody knows, that would be greay
