Yes, of course! H.264 is not allowed in 3gp4. > But if I do libx264, I can’t get MPEG-4 Visual Of course: It would be a serious bug otherwise. My question is: Why do you want "3gp6" for content that actually confirms to "3gp4" - theoretically breaking playback on other (older) devices. As said: Please test if "3gp6" really makes a difference and report back. Please do not top-post here, it is considered rude.
