Defaults to 0. Accepts the following options: Reemit PAT/PMT before writing the next packet. Makes it possible to use segment indexes as %%d in hls_segment_filename expression This When enabled every segment generated is encrypted and the encryption key See Audible AAX subsection below. The input stream has to be selected using the -map option with the ffmpeg CLI tool. If set to 1 (true), the time of the processed stream is taken into account Default is 0, which indicates MPEG-4. This can be either all, auto, or the index of the Note that a lot of things involving just decoding or encoding can be done by calling their CLI application and piping things to stdin or from stdout. If set to 1, loop over the input. hls_flag and %%d will be the specifier. Create fragments that are duration microseconds long. FFmpeg Pixel format FFmpeg Windows FFmpeg (ffmpeg) -pix_fmt ffmpeg -pix_fmts Pixel formats: I.. = Supported Input format for conversion .O. Enabled by default. output URL. causing the failure. foo-%?%?%?.jpeg will match all the filenames prefixed with reserve_index_space in which case the data is only shifted if key=value pairs separated by :, between square brackets. []{} must be prefixed Values 0. Immediately after header follows global metadata. packet written. A64 muxer for Commodore 64 video. Default is 0. When seeking, identify the closest point in each stream individually and demux packets in where PTS values are set as as wallclock time at the source. When there are multiple input files, ffmpeg tries to keep them synchronized by tracking lowest timestamp on any active input stream. These files Print metadata on video stream. video, and store it in the file out.sha256: To print an MD5 hash to stdout use the command: Apple HTTP Live Streaming muxer that segments MPEG-TS according to sub-directories are created after expanding the directory name pattern. Write an mp3 with an ID3v2.3 header and an ID3v1 footer: To attach a picture to an mp3 file select both the audio and the picture stream Default value is 0. id is an unique identifier, possibly small and very long files (since writing normal MOV/MP4 files stores info about Options for a bitstream filter must be specified in the form of opt=value. If set to 1 (true), in case the fifo queue fills up, packets will be dropped Dolby Digital Plus, also known as Enhanced AC-3, audio. the packets written so far. For example the pattern "img-%03d.bmp" will specify a sequence of publishing it repeatedly every after 30 segments i.e. is set in a sensible way even if the input originated from containers that special value to tell the muxer to re-use the previous delay. The segment number is also available in this mode, but to use it, you need to specify second_level_segment_index List of all pixel formats used by ffmpeg. serving up segments can be configured to reject requests to *.tmp to prevent access to in-progress segments reference stream. Applicable only for HTTP output. Update the list file so that it contains at most size The size, the pixel format, and the format of each image must be the aptX HD (Audio Processing Technology for Bluetooth) audio. Set delay in ms, clamped to 40-250 ms. Default is 0x0100, minimum is image. This is especially useful for MPEG-PS (VOB) files, where the order of the is 0x0001. "," separated list of allowed demuxers. Some files have multiple subsongs (tracks) this can be set with the subsong pages that are approximately duration microseconds long. To do so, reopen output AVFormatContext (in case of API Introduce a stream in the virtual file. Values containing : special characters must be The value default is 48000. This demuxer accepts the following options: Set the frame rate for the video stream. Set amount of reverb. Each stream mirrors the id and bandwidth properties from the applies, by appending a stream specifier to the option separated by Enable (1) or Disable (0) segment index correction logic. Variables which can be used are x, y, w, h, t, speed, For seekable fragmented input, set fragments starting timestamp from media fragment random access box, if present. The language can be either the 3 letters bibliographic ISO-639-2 (ISO This demuxer is used to demux FLV files and RTMP network streams. All files must have the same streams (same codecs, same time base, etc.). notice and the examples below. each file packet. RFC4180) is applied if required. strftime() documentation. ETSI 300 468. If more than one condition is specified, fragments are cut when format is guessed from the first image file in the sequence. SHA384, SHA512, CRC32 and adler32. treated as average segment duration when use_template is enabled and list are set by default to the basename of the corresponding segment Accepts the following options: Any hexadecimal value between 0x01 and 0xff as defined in representing the computed hash. Output option carrying the raw packet size in bytes. on a per-stream basis. This information can be specified from the file; This document describes the supported formats (muxers and demuxers) A list file with the suffix ".m3u8" will auto-select this format. argument must be a time duration specification, and defaults to 0. period, underscore and hyphen) and have no period at the beginning of a taken from the current time of day at the time the script is read, and the Disable AVParsers, this needs +nofillin too. which streams to actually receive. Some streams properties must be set in order to allow identifying the alongwith any ID3v1/2 or APE tags in it. published at http://example.com/live/. used for setting the length of the splitting interval. Default is 0.5. finishes. Default value is 0. platforms. Default is 1. as in the following example. recovery_wait_time seconds). lack the concept of default tracks. Must have a sample rate of 22050 Hz. encoding use case with decklink capture source where video_pts and the strftime option is enabled. be applied e.g. Set max memory used for timestamp index (per stream). Increase this to allow continue clients to download segments which the hash function used, and hash is a hexadecimal number Enable (1) or disable (0) storing all segments in one file, accessed using byte ranges. Stop muxing at the end of the shortest stream. Add the #EXT-X-INDEPENDENT-SEGMENTS to playlists that has video segments Available identifiers are "$RepresentationID$", For example, to See also Range is 0 to UINT_MAX. the maximum value allowed by the specification. characters of the box type are set as the key. Enable (1) or disable (0) use of SegmentTimeline in SegmentTemplate. This is an experimental feature. 65536. recovery attempt. Default: None. STREAM or CHAPTER) in 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). Only write platform-, build- and time-independent data. Adjust this value to set the maximum buffer size, Every segment starts with a keyframe of the selected reference stream, The default is auto. either only absolute timestamps (including the script start time) or only This example adds #EXT-X-MEDIA tag with TYPE=SUBTITLES in described by the edit list. Threshold for detecting silence. Enabled by default for HTTP/1.1 servers. The stream metadata tags title and comment map Smallest time (in seconds) shifting buffer for which any Representation is Animated Portable Network Graphics demuxer. Setting it to different and sufficiently large values ensures that the produced Muxers are configured elements in FFmpeg which allow writing The default mode It uses the SHA-256 cryptographic hash function by default, Audible AAX files are encrypted M4B files, and they can be decrypted by specifying a 4 byte activation secret. If the sequence pattern contains "%d" or "%0Nd", the first filename of can be read using the FFmpeg concat demuxer. ITU-T G.726 big-endian ("left-justified") audio. Default value is 5 seconds. This will produce init like this Specify whether to remove all fragments when finished. After global metadata there may be sections with per-stream/per-chapter The literal character % can be configure option --list-muxers. API users should be aware that callback functions (interrupt_callback, the discard flags on AVStreams (by pressing a or v in ffplay), (ffmpeg-utils)the Time duration section in the ffmpeg-utils(1) manual, (ffmpeg)Stream specifiers section in the ffmpeg(1) manual, https://bitbucket.org/mpyne/game-music-emu/overview, (ffmpeg-filters)the "amerge" section in the ffmpeg-filters manual, http://standards.iso.org/ittf/PubliclyAvailableStandards/c065274_ISO_IEC_23009-1_2014.zip, https://sites.google.com/a/webmproject.org/wiki/adaptive-streaming/webm-dash-specification, https://datatracker.ietf.org/doc/html/draft-pantos-hls-rfc8216bis, http://tools.ietf.org/id/draft-pantos-http-live-streaming, (ffmpeg-utils)the "Quoting and escaping" This field specifies the maximum difference between the timestamps of the filename, not a pattern, and the corresponding file will be continuously manifest XML. To get fixed width numbers with trailing zeroes, %%0xt format is available where x is the required width. packet. packet of the form: CRC is a hexadecimal number 0-padded to 8 digits containing the Sets maximum number of successive unsuccessful recovery attempts after which Specify the language of the track in the Matroska languages form. the duration of the respective file segments in the concatenated output Set the maximum valid delay between frames in hundredth of seconds. It is set to 0 by default. Default value is 0. The closed captions groups configured using this option are mapped to different In addition to the standard identifiers, an ffmpeg-specific "$ext$" identifier is also supported. If enabled, allow segments to start on frames other than keyframes. Write output to a temporary file, which is renamed to target filename once in result names, you may specify names for each or some of the variants Default is false. Segment the input file, and create an M3U8 live playlist (can be used within the specified duration after the segmenting clock time. When strftime_mkdir is set, the whole expanded value of filename will be written into the m3u8 segment list. When you configure your FFmpeg build, all the supported demuxers Maximum framerate in frames per second. encryption with the new key/IV and an entry in the playlist for the new key Default is 0. Specify the accuracy time when selecting the start time for a Filename of the header where the initialization data will be written. Dont create fragments that are shorter than duration microseconds long. Dynamic Adaptive Streaming over HTTP demuxer. Default value is 2. duration must be a time duration specification, Enable to set MPEG version bit in the ADTS frame header to 1 which indicates MPEG-2. img-010.bmp, etc. circumstances (avoiding basing track fragment location calculations addition to the #EXT-X-STREAM-INF tag for each variant stream in the master But here, the two media playlist with file names out_my_hd.m3u8 and protocol. Default is true. Applicable only for HTTP streams. 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. Optional syntax is "id=x,seg_duration=x,frag_duration=x,frag_type=type,descriptor=descriptor_string,streams=a,b,c id=y,seg_duration=y,frag_type=type,streams=d,e" and so on, All headers, but the PNG signature, up to (but not including) the first This example adds two #EXT-X-MEDIA tags with TYPE=CLOSED-CAPTIONS in For example the pattern "img-%03d.bmp" will match a sequence of start_number+start_number_range-1, and all the following Set the original_network_id. This example creates two hls variant streams. terminating with the ".png" suffix: output can be transparently restarted with configurable delay between retries Bluetooth SIG low-complexity subband codec audio. for the packet. This value must be specified explicitly. filenames of the form img-001.bmp, img-002.bmp, , If set to 1, expand the filename with pts from pkt->pts. This muxer feeds audio data to the Chromaprint library, as fragmented output, thus it is not enabled by default. The tee muxer can be used to write the same data to several outputs, such as files or streams. Unit is the track time scale. This option lets Metadata for the stream. Default value is 5. For ff* CLI tools, with the ffmpeg CLI tool -f data. listfile is generated. Default value is 1000. will be marked as default (if existing). This option has no effect in m2ts mode where the PMT With this option force_key_frames. demuxes them one after the other, as if all their packets had been muxed skips the current and all the remaining packets from all streams. 4-byte key required to decrypt Audible AAX and AAX+ files. to do a complete binary comparison. The description of some of the currently available demuxers follows. 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. Write segment data to filename.tmp and rename to filename only once the segment is complete. In order to force key frames on the input file, transcoding is Adjust this value to set the maximum buffer size, besides date/time values when strftime is on. Default is -1 or auto, which will write the box only in MP4 mode. Segment will be cut on the next key frame after this time has passed on the first m3u8 list. Enable (1) or disable (0) use of SegmentTemplate instead of SegmentList. At present, applicable for MPEG-PS and MPEG-TS. be an audio only stream with bitrate 64k and the third variant stream will be a Note: This is not Apples version LHLS. %*? These gains will be most pronounced at resolutions of 1080p and higher. INSTREAM-ID CC1. This prevents the muxer ending segments at a duration below segment_start_time and segment_end_time specify Set the timescale written in the movie header box (mvhd). Default is 0. Default is "init-stream$RepresentationID$.$ext$". Several bitstream filters can be specified, separated by ",". ; the pattern "i%%m%%g-%d.jpg" will match a expression besides date/time values when strftime is on. [1] [3] Contents is known to be non-malicious. Select ID3v2 version to write. list of comma separated integer numbers, in increasing order. Turning this option on by setting it to 1 will result in a stricter check default) or ignore. Set cutoff i.e. silence detection. extension. By default this option is set to 0 (false) and in case of Disable to use the earliest_presentation_time from the sidx box. If set to 2, will set frame timestamp to the modification time of the image file in addition to the #EXT-X-STREAM-INF tag for each variant stream in the master checks without having to individually do a binary comparison on each. Set maximum buffering duration for interleaving. Set output format options using a :-separated list of key=value Applicable only when the utc_url option is enabled. Please note that descriptor string should be a self-closing xml tag. Set the mpd update period ,for dynamic content. If the stream specifier is not specified, the bitstream filters will be Each frame CSV escaping (according to HLS playlists generated with Example: The MP3 muxer writes a raw MP3 stream with the following optional features: The muxer supports writing attached pictures (APIC frames) to the ID3v2 header. This guide focuses on the encoder libx265 which can offer around 25-50% bitrate savings compared to H.264 video encoded with libx264, while retaining the same visual quality. e.g. Reserve the specified amount of bytes for the OpenDML master index of each The Game Music Emu library is a collection of video game music file emulators. Use the given HTTP method to create output files. Option to access, open and probe the file. Default value is -1 which Default value is This option is enabled by default. Global System for Mobile Communications audio. img.jpeg you can employ the command: The pattern is interpreted like a glob() pattern. AVFormatContext options or using the libavutil/opt.h API
