The command generates the files named image1.jpg, image2.jpg and so on… $ ffmpeg -i video.flv image%d.jpg Split Video into ImagesĪfter successful execution of above command you can verify that the video turn into multiple images using following ls command. To turn a video to number of images, run the command below. $ ffmpeg -i video.flv Hide FFmpeg Version Information 2. This option can be used to suppress printing this information.įor example, if you run the above command without adding -hide_banner option it will print the all FFmpeg tools copyright information as shown. Note: The -hide_banner option is used to hide a copyright notice shown my ffmpeg, such as build options and library versions. $ ffmpeg -i video.flv -hide_banner Get Video Information Remember you have to specify an ouput file, but in this case we only want to get some information about the input file. To get information about a file (say video.mp4), run the following command. If you are new to this tool, here are some handy commands that will give you a better idea about the capabilities of this powerful tool. ffmpeg -formats command to list all supported formats.

15 FFMPEG Command Examples in Linuxįor more details about FFmpeg and steps to install it in different Linux distros, read the article from the link below:įFmpeg Multimedia Framework Installation Guide on Linux – Part 1 Useful FFmpeg CommandsįFmpeg utility supports almost all major audio and video formats, if you want to check the ffmpeg supported available formats you can use. The resulting output files should be safe to be passed to the Apple segmenter.In this article we are going to look at some options and examples of how you can use FFmpeg multimedia framework to perform various conversion procedures on audio and video files. Note: It is important to watch the resulting muxing overhead which might lower the effective bitrate a lot! For MPEG-4 TS something like the following should work:įfmpeg -i inputfile -vcodec libx264 -vpre slow -vpre baseline -acodec libfaac -ab 128k -ar 44100 -intra -b 2000k -minrate 2000k -maxrate 2000k outputfile The relevant piece is the "-intra" switch. The parameter for this depends on the output video codec.Īn ffmpeg command line for MPEG-2 TS can look like this:įfmpeg -i inputfile -vcodec mpeg2video -pix_fmt yuv422p -qscale 1 -qmin 1 -intra outputfile To allow frame-exact splitting on problematic input files the easiest way is to blow them up to consist only of I-frames.
As the segmenter only supports transport stream only MPEG-2 TS and MPEG-4 TS do make sense. When using the Apple segmenter the only safe way to split files is to convert into an intermediate format which allows frame-exact splitting.
missing audio+video between otherwise audio-synchronous consecutive segments.missing video frames at the start of each segment.asynchronous audio in some or all segments.Wether you split the file using ffmpeg or the Apple segmenter tool you often end up with The problem lies with frame exact splitting of arbitrary video input material.
When preparing videos for Apples HTTP streaming for iPad/iPhone you need to split your video into 10s chunks and provide a play list for Quicktime to process.
