FFmpeg supports all popular audio and video formats. Or you can running the command ./ffmpeg -formats to get a list of every format that is supported by your FFmpeg installation. If you are just getting started, here are some commands that will give you a good idea of the capabilities of this tool.
If you want to split a large video into multiple smaller clips without re-encoding, ffmpeg can help. This command will split the source video into 2 parts - one ending at 50s from the start and the other beginning at 50s and ending at the end of the input video.
You can use the -vcodec parameter to specify the encoding format to be used for the output video. Encoding a video takes time but you can speed up the process by forcing a preset though it would degrade the quality of the output video.
If you have multiple audio or video files encoded with the same codecs, you can join them into a single file using FFmpeg. Create an input file with a list of all source files that you wish to concatenate and then run this command.
You can change the speed of your video using the setpts (set presentation time stamp) filter of FFmpeg. This command will make the video 8x (1/8) faster or use setpts=4*PTS to make the video 4x slower.
Stack Exchange has a good overview to get you started with FFmpeg. You should also check out the official documentation at ffmpeg.org or the wiki at trac.ffmpeg.org to know about all the possible things you can do with FFmpeg.
Since audio is an important part of a complete video, you can also use the tag to put an audio file on a web page. But in most cases, you should use the tag for this purpose for the appropriate user experience.
GIF is an image format that supports animated images. It can adapt 256 colors and uses lossless compression technique to contain images. It can also contain texts. It can contain low sized image animation. So it is frequently used in web publishing. It applies LZW compression algorithm to compresses low colored images.

FFmpeg is a very robust tool for different types of media operations, including extracting images from a video. You can use it to generate thumbnails for your videos or take a screenshot of the video at any given time.
FFmpeg is a complete, cross-platform solution to record, convert and stream audio and video. It can decode, encode, transcode, mux, demux, stream, filter and play pretty much any media file in any format. It is also highly portable as it compiles and runs in a wide variety of build environments, machine architectures, and configurations like Linux, Mac OS X, Microsoft Windows, etc.
By default, FFmpeg uses a frame rate which is the same as the video source. Frame rate is also known as frame per second (fps). It is the measurement of how quickly a number of frames appear within a second. As FFmpeg extracts images from a video following its frame rate, the frame rate will decide how many images will be extracted for every second of the video.
From the screenshot above, the frame rate of the video is 30 fps. This means that 30 images will be extracted for every second of the video when running the basic command ffmpeg -i input.mp4 %04d.png. As a result, a total of 274 images will be generated from the input video.
You can change the frame rate by adding the argument -vf fps or -filter:v fps with the number of frames to the basic command. It is a filter that will convert the video to the specified constant frame rate by duplicating or dropping frames as necessary.
If the original frame rate of the video is higher than the specified frame rate, the frames in the video will be dropped to match the frame rate specified. On the contrary, the frames of the video will be duplicated if the original frame rate is lower.
For example, adding -vf fps=1 to the basic command will re-encode the video to 1 fps. The frames of the video will be dropped as the original frame rate is 30 fps. The total number of images extracted from the video will become 9 (1 image x 9.13 seconds).
You can do this by adding the same argument -vf fps but with different values. You can extract images at a constant time interval by using fractions. For example, -vf fps=1/4 will output an image every 4 seconds.
The -ss argument tells FFmpeg to seek x seconds into the input file. We can use the same argument to tell FFmpeg to seek x seconds into the input video and starts extracting images from that specific point.
The command above seeks 00:04 into the video and starts extracting images from that point until the end of the video. You will have a total of 154 images as the total duration of the video becomes 5.13 seconds long (30 images x 5.13 seconds).
For example, the command above sets the width to 640 pixels. The height of the output images will be calculated automatically according to the aspect ratio of the input video. The resulting images will have a dimension of 640357 pixels.
If you want to specify the height instead, set the first value to -1 and the second value to the new height. For example, adding -vf scale=-1:357 will set the height to 357 pixels and generate images with the same dimension as the image above.
You can use Bannerbear Video Generation API to auto-generate videos from your images. The API auto-generates videos from a template which you can place different elements like watermarks, texts, company logos, etc. It is very handy when you always have a new video or a new set of images which needs to be watermarked.
Bannerbear Video Generation API can also auto-transcribe your videos and add subtitles to them. In fact, the subtitles in the video that we are using for this FFmpeg tutorial is also generated using the API.
Starting from June 2010, Samsung released a series of mobile phones and tablets named starting from Samsung Galaxy like Samsung Galaxy S3, Galaxy S2, Galaxy Tabe, Galaxy Note, Galaxy Ace and the newly launched Samsung Galaxy S4.

The fact is Samsung can play most of MP4 files. Several special MP4 videos will not be played as MP4 is a container video format which may encode with a variety of codecs like H.264, MPEG-4, Xivd, DivX, MPEG-4 ASP etc. or with subtitles or multi-channel audio tracks. As MPEG-4 AVC H.264 codec, support is limited to the required specifications. If your MP4 files are using audio and video codec that Samsung Galaxy cannot support or your MP4 files cannot meet the supported specifications of audio and video codec, your Samsung Galaxy phones or tablets will fail to play MP4 files. Even you download different Android video player, they still fails to play.
In order to successfully play MP4 on Samsung Galaxy S4, Samsung Galaxy S3, Samsung Galaxy S2, Samsung Galaxy Tab, Samsung Galaxy Note and Samsung Galaxy Ace, a better solution is to convert MP4 to Samsung Galaxy supported MPEG-4 Video with require specifications. This article will guide you step-by-step to convert MP4 to successfully play MP4 on Samsung Galaxy S4/S3/S2/Tab/Note/Ace.
