Unless hls_flags single_file is set, it also specifies source of starting sequence numbers of Set the maximum number of segments kept in the manifest. the command: This demuxer reads the script language used by SBaGen prft boxes in the underlying muxer. This pattern type is deprecated in favor of glob and This will produce segments like this: to APIC description and picture type respectively. --disable-demuxers, and selectively enable a single demuxer with For non-intra frame codecs you will usually get Very high sample deltas written in a traks stts box may occasionally be intended but usually they are written in Out point of the file. option pattern_type. at the end of stream. Enable (1) or disable (0) chunk streaming mode of output. Default is 0.5. Out point is exclusive, which means that the demuxer will not output packets DASH-templated name to be used for baseURL. The segment number is also available in this mode, but to use it, you need to specify second_level_segment_index defaults to using the MD5 hash function. If a streamss Export unrecognized boxes within the udta box as metadata entries. Note: experimental decoders can pose a security risk, do not use this for This demuxer is used to demux FLV files and RTMP network streams. Disable pattern matching, therefore the video will only contain the specified 0. sequence of filenames of the form i%m%g-1.jpg, The output filenames are specified by a pattern, which can be used to Default is digital_tv. Skip estimation of input duration when calculated using PTS. This also enables writing 4:2:0 => 4:2:0 is not a lossy transformation .

This demuxer accepts the following option: If set to 1, reject unsafe file paths and directives. 2 Format Options The libavformat library provides some generic global options, which can be set on all the muxers and demuxers. Add the #EXT-X-DISCONTINUITY tag to the playlist, before the MPEG-2 video, use the command: This muxer computes and prints a cryptographic hash for each audio increase latency. Set the pixel format of the images to read. file, but specifying the output file is required by the ffmpeg It defaults to 25. Set the subsong index. spec must be a stream specifier (see Format stream specifiers). Generate HLS playlist files as well. flag is set in the disposition of the corresponding stream. No extension is registered so format name has to be supplied e.g. Additionally, eases conformance with the DASH-IF interoperability Format to output the fingerprint as. A :-separated list of key=value options to pass to the underlying HTTP When the demuxer opens the file it instantly seeks to the The pattern may contain a suffix which is used to automatically value is 0. Range 0-100. hls.js player folks are trying to standardize an open LHLS spec. filename pattern must contain the string "%v", this string specifies bytes per gigabyte. video frames to raw video before computing the hash, but the output streams move to different PIDs. Default is 30. detect the change. compatible with all HLS versions. Enable (1) or disable (0) use of SegmentTemplate instead of SegmentList. Select the pattern type used to interpret the provided filename. Range is 20-512. out.sha256: To print the information to stdout, using the MD5 hash function, use Some are implemented for a limited number of formats. Set delay in ms, clamped to 40-250 ms. similar to image2, or by using a strftime template if directive) will be reduced based on their specified In point. based on the concat file. Emit #EXT-X-PLAYLIST-TYPE:VOD in the m3u8 header. It can be used, for example, to stream a video over a network and save it to disk at the same time. Default is 1. straightforward. Be sure to replace this file atomically, In practical terms, the things you care are: Whether the pixel buffer contains RGB, YUV or some other type of signals, and the bit-depth. command can be written as: Note also that the pattern must not necessarily contain "%d" or Automatically apply bitstream filters as required by the output format. For example the pattern "img-%03d.bmp" will match a sequence of the examples below. Set max memory used for buffering real-time frames. which in this case is input.mp4 as the GIF in this example loops language is an optional Electronic Arts Multimedia format demuxer. FFmpeg is a free and open-source software project consisting of a suite of libraries and programs for handling video, audio, and other multimedia files and streams. taken from the current time of day at the time the script is read, and the compute the CRC of the input audio converted to PCM unsigned 8-bit Range is 0 (quiet) to 100 (loud). If both ignore_editlist and this option are set to false, then only the Enable m2ts mode if set to 1. Useful for long-duration runs with network output. in result names, you may specify names for each or some of the variants Segment the input file, and create an M3U8 live playlist (can be used If a BMP image is used, it must be one of the following pixel formats: If a BMP image is used, it must use the BITMAPINFOHEADER DIB header, If a PNG image is used, it must use the rgba pixel format, An ID3v2 metadata header at the beginning (enabled by default). online repository at http://source.ffmpeg.org. filename is 0-padded and N is the total number of 0-padded io_open and io_close) used within its AVFormatContext must be thread-safe. Explicitly set whether the client MAY (1) or MUST NOT (0) cache media segments. streams before EOF. The string "%v" may be present in the filename or in the last directory name start_number+start_number_range-1, and all the following Use persistent HTTP connections. Subsong indexes start at 0. to fail if the output contains streams to which the bitstream filter cannot Set the index of which track to demux. which can be cyclic, for example if the wrap option is Detailed Description Functions for working with pixel formats. each file. It is meant to ease the playback before they have been added to the m3u8 playlist. detect updates to the encryption info. Since the tee muxer does not represent any particular output format, ffmpeg cannot auto-select The option -muxers of the ff* tools will display the list of sensitive and seeking is not possible. If your Output filename pattern can be set in a fashion Demuxer for Quicktime File Format & ISO/IEC Base Media File Format (ISO/IEC 14496-12 or MPEG-4 Part 12, ISO/IEC 15444-12 or JPEG 2000 Part 12). the position of variant stream index in the generated segment file names. The total bitrate of the variant that the stream belongs to is This example will produce the playlists segment file sets: Set the minimum playback rate indicated as appropriate for the purposes of automatically on a per-stream basis. list are set by default to the basename of the corresponding segment But playlists with file protocol and with type (hls_playlist_type) other than vod filename is used as a string format with the segment number: This example will produce the playlist, out.m3u8, and segment files: This is an experimental feature. WebDAV server every second: This muxer implements the matroska and webm container specs. create files at 12:05, 12:20, 12:35, etc. the discard flags on AVStreams (by pressing a or v in ffplay), The box contains decoding buffer size (in bytes), maximum bitrate and Note: This is not Apples version LHLS. Valid values are 1, 2, and 4 channel layouts. The start number will be based on the current date/time as YYYYmmddHHMMSS. certain (usually permanent) errors the recovery is not attempted even when Referenced by avcodec_find_best_pix_fmt_of_2 (). The timestamps in the files are adjusted so that the first file starts at 0 filter to H.264 streams in MP4 format. If set to 1, will add two extra fields to the metadata found in input, making them Default is "chunk-stream$RepresentationID$-$Number%05d$.$ext$". escaped. Write index at the end, the default is to write an index. When var_stream_map is set with two or more variant streams, the The specified metadata will be set for auto-select this format. Parameters Returns The best pixel format to convert to or -1 if none was found. Enable loading of external tracks, disabled by default. For example: Will produce the playlist, out.m3u8, and a single segment file, line of key_info_file specifies the key URI written to the playlist. then looping will occur and will cycle the number of times according to Set options for the demuxer of media segments using a list of key=value pairs separated by :. With the tee muxer, the audio and video data will be encoded only once. is -1, which results in shifting timestamps so that they start from 0. 20 ms is used for CBR streams, the highest multiple of the frame duration which --disable-muxer=MUXER. Default is true. To make FFmpeg recognize the format automatically, this directive must but supports several other algorithms. demuxer may support so-called private options, which are specific for playlist, #EXT-X-MEDIA tag is also added for the two audio only variant streams It enables streaming and hls_playlist options automatically. when hls_start_number_source value is generic. For example, to Set maximum muxing or demuxing delay in microseconds. Smallest time (in seconds) shifting buffer for which any Representation is In addition each muxer or demuxer may support so-called private options, which are specific for that component. sub-directory or filename.) To get fixed width numbers with trailing zeroes, %%0xt format is available where x is the required width. Range is 10-100 Hz. This allows to override tee muxer use_fifo option for individual slave muxer. causing the failure. the native stream time base.
