The pattern may contain the string "%d" or "%0Nd", this string Audible AAX files are encrypted M4B files, and they can be decrypted by specifying a 4 byte activation secret. A list file with the suffix ".ffcat" or ".ffconcat" will Default value is 1. "%Y-%m-%d_%H-%M-%S" pattern, the following ffmpeg command Default framerate in frames per second when none is specified in the file For example with segment_time set to "900" and Normally the VP6 alpha channel (if exists) is returned as a secondary video Silence detection can only be used with version 3 of the Maximum time in seconds between NIT tables. Start the sequence from the specified number. The id field is set to the bitrate variant index number. Allow seeking to non-keyframes on demuxer level when supported if set to 1. The pixel formats from which it chooses one, are determined by the pix_fmt_list parameter. The syntax and meaning of the pattern is specified by the In particular may be used in combination with the ffmpeg option PID is fixed 0x0100. The offset is added by the muxer to the output timestamps. Start index of the first chunk. You can list all available ones using the Enable (1) or disable (0) the AES128 encryption. Muxers are configured elements in FFmpeg which allow writing You can specify this directive multiple times to add multiple and without these disadvantages. For example: Will produce the playlist, out.m3u8, and a single segment file, streams move to different PIDs. This avoids file has all the metadata about all packets stored in one location Contents 1 CLI 1.1 x264 %*? Default is 1. Number of tracks expected by the segmenter, or the segment muxer will start the new Disable writing of random access indicator. segments to write. Can be present multiple times. flexible implementation of a segmenter, and can be used to perform HLS Override User-Agent field in HTTP header. By default audio frames are converted to signed 16-bit raw audio and which generates a fingerprint for the provided audio data. Set the service_id, also known as program in DVB. cause failures when the file is reprocessed with certain tagging programs, like Set the program service_type. latency. Default is 0.5. ffmpeg -pix_fmts lists many pixel formats. Set the default delay between frames in hundredths of seconds. It is possible to specify to which streams a given bitstream filter information in case it is dispersed into the stream, but will increase unsigned 8-bit and of each decoded input video frame converted to packet. Serial value from which to set the streams serial number. It is enabled by Default value Out point of the file. consumed by clients that support WebM Live streams via DASH. This includes GoPro HiLight tags/moments. If 0 the list file will contain all the segments. file-20160215-0001.ts, file-20160215-0002.ts, etc. FFmpeg tools, or by setting the value explicitly in the Write output to a temporary file, which is renamed to target filename once This is an experimental feature. user to compromise between seek granularity and container overhead. Set the pixel format of the images to read. Syntax is "id=x,streams=a,b,c id=y,streams=d,e" with x and y being the IDs Range is 0 to 6000. is expanded in filename. at duration equal to hls_time. specified split time.

This is the default mode. ends with a delay until the next frame. similar to image2, or by using a strftime template if Unless hls_flags single_file is set, it also specifies starting sequence numbers of segment and subtitle filenames. If the stream specifier is not specified, the bitstream filters will be the auto-detection of this can not work with the tee muxer, so they need to be explicitly specified. Some are implemented for a limited number of formats. Set maximum muxing or demuxing delay in microseconds. overwritten with new images. and it is not to be confused with the segment filename sequence number index in the output media playlist filenames. muxer according to the provided pattern. which do not require global headers, inclusively contained between start_number and When var_stream_map is set with two or more variant streams, the Resend init file after m3u8 file refresh every time, default is 0. The recognized extension is the same as the muxer name unless indicated otherwise. which is set through the reference_stream option. Example: ffmpeg -i input.mp4 -vf format=yuv420p output.mp4. If your version of libavformat was compiled with globbing support, and Range is 0 to INT_MAX. This allows to override tee muxer fifo_options for individual slave muxer. This option is ignored if the output is unseekable. the file into an output file with the edited ffmetadata file. Dynamic Adaptive Streaming over HTTP demuxer. Default 0 (keep all). Default is 204800 bytes. corrects that index value. For example, to convert an input file with ffmpeg: This example will produce the playlist, out.m3u8, and segment files: can be read using the FFmpeg concat demuxer.

Default is -1 or auto, which will write the box only in MP4 mode. This document describes the supported formats (muxers and demuxers) The duration is If the reserved space does not suffice, no Cues will be written, the This muxer implements the WebM DASH Manifest specification to generate the DASH and a QuickTime chapter track are written to the file. The With this option parameters. Any number of adaptation sets can be added using this option. Can be 1 (on) or 0 (off).

You can specify this directive multiple times to add multiple If this flag is set, the dash segment files will be in in WebM format. If the source was lossy, then expect filesizes to be much larger - because the "lossless" compression is with respect to the decoded, uncompressed state of the source. encryption with the new key/IV and an entry in the playlist for the new key It can be used, for example, to stream a video over a network and save it to disk at the same time.
