A separate hint track is used to include streaming information in the file. ![]() Most kinds of data can be embedded in MPEG-4 Part 14 files through private streams. Like most modern container formats, it allows streaming over the Internet. MPEG-4 Part 14 or MP4 is a digital multimedia format most commonly used to store video and audio and store other data such as subtitles and still images. On a Ubuntu 10.04, I am trying to encode a raw video (YUV format) to a H.264 encoded video using below ffmpeg commands: ffmpeg -i input.mp4 output.h264 but I get an error saying Unsupported codec for output stream 0.0 Then when I try this option: ffmpeg -i input.mp4 -formats h264 output.h264 it still does not encode. The H.264 video format has a broad application range covering all forms of digitally compressed video, from low-bit-rate Internet streaming applications to HDTV broadcast and Digital Cinema applications with nearly lossless coding. ffmpeg -i -i video.h264 -strict experimental av.mp4 the result is mp4 file with both video and audio streams but the video is playing almost 3 times faster then the original h264 stream. It is by far the most commonly used format for the recording, compressing, and distributing of video content, used by 91% of video industry developers as of September 2019. H.264 is a video compression standard based on block-oriented, motion-compensated coding. International Organization for Standardization
