  • convert exr filesequence with ffmpeg and x264 [closed]

    29 novembre 2012, par user1863947

    When i convert a exr sequence into quicktime mov file using ffmpeg and x264 codec it codes the video but in quicktime player and windows media player its just black ! but when i open it up with vlc i can see the image and it looks fine. When i try the same thing with a jpg sequence instead of exr it works perfect ! does anyone have an idea what that could be ?

    here is my ffmpeg code :

    ffmpeg -y -i C:/seq_v001.%04d.exr -c:v libx264 -preset slow -crf 17 C:/out.mov

    Here is the console output :

  • ffmpeg mp4 to mpeg and back again

    5 décembre 2012, par brux

    I am concatenating mp4 files, from research I have found out you must first encode to mpeg and contatenate those, then convert the larger mpeg file back to mp4.

    For simplicity I am just attempting to convert a.mp4 to mpeg and then back to mp4 (i dont need to worry about the concatenation for now)

    Here is how I first convert to my intermediary mpeg from mp4 :

        ffmpeg -i a.mp4 -q:v 2 -vcodec mpeg2video -acodec copy b.mpg

    The file is encoded with no errors, to convert back to mp4 I do :

        ffmpeg -i b.mpg -vcodec libx264 -acodec copy out.mp4

    Everything seems to work with no errors but out.mp4 just plays the first few frames and then freezes, and the time is skipping randomly as the duration passes for the file. No sound is heard also.

        *****************************************                              
    
    Here is the output of the first command
