Hi, I'm trying to generate a mpeg2 file like this: ffmpeg -y -threads auto -t 5 -framerate 30 -i "images_%05d.png" -r 30 -pix_fmt yuv422p -c:v mpeg2video -b:v 50000000 -qmin 1 -qmax 18 -q 3 -g 1 -flags2:v +local_header -vf "crop=960:540:0:0" test.m2v
The problem is, that it seems the option -flags2:v +local_header has no effect. I also tried with -bsf:v dump_extra, no luck too. Encodings with and without that options have exactly the same size, I guess the headers should add some bytes. The file plays fine with all common players, but I need to encode for a videoserver, which needs the headers in every GOP for fast seeking. Without the headers it shows only the first frame. I'm using ffmpeg version 2.5.3-tessus on OSX 10.8.5. Is there anything I'm missing?
