I would guess that at this point (which corresponds to your 4..5
seconds), something is different about the JPEG images.
You are totally right. I just found out that it's only one image that produces the problem. This is one of the good images. It's a HDR image from a Canon 6D: http://www.astro-electronic.de/IMG_043.JPG The next image produces the problem. When I took this image, the camera was accidently set to the wrong color temperature, incandescent lamp instead of daylight. Of course the image was much too blue, and I did try to correct the colors with IrfanView. So this is the image that ffmpeg doesn't like: http://www.astro-electronic.de/IMG_044.JPG Michael _______________________________________________ ffmpeg-user mailing list ffmpeg-user@ffmpeg.org http://ffmpeg.org/mailman/listinfo/ffmpeg-user To unsubscribe, visit link above, or email ffmpeg-user-requ...@ffmpeg.org with subject "unsubscribe".
