Hi to ffmpeg seniors and experts I am using windows platform and I have created a series of video in pure format of *.264 from raw format by the below command:
ffmpeg -f rawvideo -pix_fmt yuv420p -s 360x240 -i C:\1.yuv -an -vcodec libx264 -threads 0 -s 360x240 -f h264 C:\1.264 I want to extract I-Frames which are created in adaptive mode in encoding phase. i use the below command: ffmpeg -i C:\ 1.264 -vsync 0 -vf select="eq(pict_type\, PICT_TYPE_I)" C:\ Test\IFrames\I-Frm-%03d.jpeg Its a short video and i just get 4 images but the images does not looks correct images, They are not sharp and clear images. BTW, adaptive I-Frame are expected t be located at the start of a new group of pictures, after any big changes in the scene, but these extracted image are not showing this. do you know whats my mistake or whats wrong? -- Amir
