  • What is wrong with this video produced with libx264 ?

    6 janvier 2015, par Natal

    I’ve been trying to get a c++ wrapper around libx264 (version 142) to work. I am able to produce a video with x264 with no errors during encoding. Most standard video players (QuickTime, VLC...) are NOT able to read it but don’t display any errors. However, mplayer is able to read it.

    I am not able to determine what is wrong with it (Corrupt header ? Corrupt data ?).

    The video is available here : https://www.dropbox.com/s/godnip85pezdi89/test_h264.mp4?dl=0

    The class wrapped around libx264 I use to encode the video is here : https://gist.github.com/anonymous/4eb46b838fcf84ed02aa

    Any help to identify what I’m doing wrong would be greatly appreciated.

    Thank you !

  • VLC freezes for low 1 FPS video created from images with ffmpeg

    15 janvier 2020, par user2861936

    I am creating a short video from a sequence of 100 images using ffmpeg. There are several articles that helped me put together a command, but the one I’m using is directly taken from ffmpeg images-to-video script anyone ?.

    The following command produces a video file that plays well in all video players I have (OS X).

    cat input/*.jpg | ffmpeg -f image2pipe -r 10 -vcodec mjpeg -i - out.mp4

    But if I change it to,

    cat input/*.jpg | ffmpeg -f image2pipe -r 1 -vcodec mjpeg -i - out.mp4

    It plays well in all but VLC media player. VLC displays the initial 1 to 3 images, then just freezes on the frame. I’ve tested a few different frame rates, and it seems the cutoff that breaks the video playback in VLC lies somewhere between 1.125 and 1.175.

    Any advice on what I’m dealing with here would be much appreciated.
