This is curious - it's almost as if ffmpeg doesn't recognize this as a valid video. Can you run "file video1.264" for us? Or even better, can you provide a small sample for us to take a look at and see for ourselves? > "I ran the command after giving full permission to access the file. (chmod 777 Video1.264)" > Again, your commands use sudo to run ffmpeg as root. You shouldn't have to do this. With a 777 permission, the file is wide open for anyone. Your restriction would then be the directory permissions. > After searching the internet, I saw a post suggesting use -f to force ffmpeg h264 treat Video1.264 file in h264 format. As I understand the error in the first command it was that ffmpeg could not identify the file type. Once put -f H264 format was identified.
