I've always used -f h264 until I ran into Hauppauge WinTV Version 10 using: ffmpeg -i "[SOURCE_FILE]" -f mp4 -vcodec libx264 -preset ultrafast -profile:v main -acodec aac "[DEST_FILE].mp4 On the flip, I've never seen a *.h264 file name. If I'm not mistaken, the "-f" specifies the format or the container of the video/audio stream. So when specifying, "-f h264", format is assuming a video only container? _______________________________________________ ffmpeg-user mailing list ffmpeg-user@ffmpeg.org https://ffmpeg.org/mailman/listinfo/ffmpeg-user To unsubscribe, visit link above, or email ffmpeg-user-requ...@ffmpeg.org with subject "unsubscribe".
