  • ffmpeg width not divided by 2 (2247x1500) [duplicate]

    24 juin 2021, par Ruiqing Wu

    [libx264 @ 0000021db7838c80] width not divisible by 2 (2247x1500)
Error initializing output stream 0:0 — Error while opening encoder for output stream #0:0 - maybe incorrect parameters such as bit_rate, rate, width or height
Conversion failed !

    


    My code was :
ffmpeg -y -framerate 10 -start_number 0 -i "a__%08d.jpg" -c:v libx264 -vf scale=-1:1500 -pix_fmt yuv420p d :\lustars1.mp4

    


    Is there a way to bypass this ?

    


  • How can I increase the size of an mp4 file to a specific value ?

    20 juin 2023, par zoomer-girl

    this is my first time here. I'm not a programmer. Question : For example, I have a video file size of 1500 mb, I need to increase the video size to 3500 mb, without changing the video quality or lenght. It is important that the final file size should have an accuracy of +- 10 mb. I thought it could be done by adding a second empty audio track using FFMPEG, but I didn't succeed :( If anyone knows how to do this, please help

    


    I tried to add an empty audio track lasting several hours and with a bitrate of 192 kbps using FFMPEG. However, the file size did not change much, although this audio track appeared in the VLC player, but for some reason it showed that the bitrate was 1 kbps

    


  • How to rescale image based on long side with ffmpeg ?

    10 février 2024, par mj2

    I want to rescale an image based on the long side of the image.

    


    If I have a landscape format image e.g. 4000x3000px then this is the right command :

    


    ffmpeg -i input.jpg -vf scale=1500:-1 scaled.jpg

    


    If I have an upright format image e.g. 3000x4000px then this is the right command :

    


    ffmpeg -i input.jpg -vf scale=-1:1500 scaled.jpg

    


    Can I do this in one command ? Another option is to check the format manually with ffmpeg but I don't know how.
