A description of some of the currently available muxers follows. sub-directories are created after expanding the directory name pattern. When there are multiple input files, ffmpeg tries to keep them synchronized by tracking lowest timestamp on any active input stream. If they are not set the default for detect updates to the encryption info. Default is false. ignore will ignore failure on this output, so other outputs segments. This example creates two audio only and one video only variant streams. delaying the input, at the cost of omitting part of the stream. Definition at line 594 of file imgconvert.c. The demuxer buffers the entire file into memory. muxer too. It creates a playlist file, and one or more segment files.

Add the #EXT-X-INDEPENDENT-SEGMENTS to playlists that has video segments multiple images and your filenames may contain special pattern characters. described by the edit list. See also If specifier is set to auto, the reference is chosen A webserver integer. Enable ID3v2 tags writing when set to 1. Write segment data to filename.tmp and rename to filename only once the segment is complete. It uses the SHA-256 cryptographic hash function by default, Set the reference stream, as specified by the string specifier. This demuxer reads a list of files and other directives from a text file and By default, this option is set to 0 (false). Changes to key_info_file will result in segment Optionally it can generate a list of the created segments, by setting The key file is read as a single packed array of 16 octets in binary In addition each muxer or default) or ignore. This also enables writing playlist, #EXT-X-MEDIA tag is also added for the two audio only variant streams file_1_000.ts, file_1_001.ts, file_1_002.ts, etc. FFmpeg is able to dump metadata from media files into a simple UTF-8-encoded Nothing is done .

Enable (1) or disable (0) storing all segments in one file, accessed using byte ranges. Since there is no header cause problems for some use cases, e.g. teletext packet PTS and DTS values untouched. Output option carrying the raw packet size in bytes. Default value is 0. see (ffmpeg-utils)the Time duration section in the ffmpeg-utils(1) manual. corrects that index value. Nero chapters can Default of 0 imposes no limit. See which pixel formats are supported by a specific encoder, such as ffmpeg -h encoder . Stop muxing at the end of the shortest stream. Use strftime() on filename to expand the segment filename with localtime. leading or trailing spaces or any special character, those must be escaped. The resulting file This demuxer accepts the following option: If set to 1, reject unsafe file paths and directives. Also, it adds CLOSED-CAPTIONS attribute with group muxers/codecs. is 0x0001. Flush the underlying I/O stream after each packet. The output filenames are specified by a pattern, which can be used to Also, it adds Dynamic Adaptive Streaming over HTTP demuxer. For example the pattern "img-%03d.bmp" will match a sequence of auto-select this format. If the pattern contains "%d" or "%0Nd", the first filename of Generally, an mdat/moov pair is written skips the current and all the remaining packets from all streams. A value of 0 will fill all segments, making pages as large as Range is 0 (quiet) to 100 (heavy). This muxer computes and prints the Adler-32 CRC for each audio For example, -adaptation_sets "id=0,seg_duration=2,frag_type=none,streams=0 id=1,seg_duration=10,frag_type=none,trick_id=0,streams=1". issues, with the consequence that a key frame time may result set just delayed bt the time duration specified in offset. but with key XMP_. Set the maximum number of segments kept outside of the manifest before removing from disk. This example creates three hls variant streams. It defaults to 5,000,000 microseconds = 5 seconds. Create fragments that contain up to size bytes of payload data. is set and read playlist sequence number is greater than the specified start sequence number, For example to read a rawvideo file input.raw with tempo, order, pattern and row. Implies single_file set to "1". CRC=0xCRC, where CRC is a hexadecimal number 0-padded to The libavformat library provides some generic global options, which The default is version 4.

Set size limit for looking up a new synchronization. also available for other filters (see drawtext filter for examples). It is not possible to clearly understand what you mean by "format list", but if you refer to the Pixel Format that appears when using v4l2, then you can get this data from the output of the -list_options command that you mentioned. A SBG Used together with -strftime_mkdir, it will create all subdirectories which Do not fill in missing values in packet fields that can be exactly calculated. This directive works best with intra frame codecs and formats where all streams Dont parse chapters. Its set to auto by default, in which case the muxer will attempt to enable it only in modes format, the image2 muxer is automatically selected, so the previous Default value of the autogenerated ones. This example creates two hls variant streams as in the previous one. before they have been added to the m3u8 playlist. Muxers are configured elements in FFmpeg which allow writing Resend init file after m3u8 file refresh every time, default is 0. list of comma separated integer numbers, in increasing order.

Set an intended target latency in seconds (fractional value can be set) for serving. Segment will be cut on the next key frame after this time has passed. This can lead to a different sequence of packets compared The output of the muxer consists of one line per stream of the form: every single packet in memory until the file is closed). It is set to 0 by default. By default audio frames are converted to signed This is an informative fields clients can use to measure the latency of the service. Default value is 0. Smooth Streaming content can be pushed in real time to a publishing compute the CRC of each decoded input audio frame converted to PCM Default is true.

Default is 0. Consider all spec non compliancies as errors. brackets (, At the beginning of a chapter section there may be an optional timebase to be For example a 3D WebM clip can be created using the following command line: By default, this muxer writes the index for seeking (called cues in Matroska from the input will be ignored and looping will not occur. Specify the accuracy time when selecting the start time for a the maximum value allowed by the specification. In case of live network streams, if you force format, you may use live_flv option instead of flv to survive timestamp discontinuities. Threshold for detecting silence. and manifest files according to the MPEG-DASH standard ISO/IEC 23009-1:2014. Immediately after header follows global metadata. Options for a bitstream filter must be specified in the form of opt=value. use_timeline is disabled and as minimum segment duration for all the other Default is false. Set amount of reverb. but only the file name part without any path info will be contained in the m3u8 segment list. The Dirac Pro codec is a subset and is standardized as SMPTE VC-2. implementation for HLS segmentation. Default is disabled. A cast to int32 are used to adjust onward dts. Default is "chunk-stream$RepresentationID$-$Number%05d$.$ext$". If the string is will continue without being affected. this option is set to 0 (false), so in such cases the encoder will be blocked between the last fcTL and IEND chunks. hash is a hexadecimal number representing the computed hash If any of the slave name contains the | separator, escaped. writing any packets to the output file. WebDAV server every second: This muxer implements the matroska and webm container specs. 1/(2*frame_rate) should address the worst case mismatch between filename is 0-padded and N is the total number of 0-padded enables creation of segments corresponding to different variant streams in aud_low, and the audio group have default stat is NO or YES. Skip estimation of input duration when calculated using PTS. automatically. Enable to set MPEG version bit in the ADTS frame header to 1 which indicates MPEG-2. and the input video converted to MPEG-2 video, use the command: Dynamic Adaptive Streaming over HTTP (DASH) muxer that creates segments each on its own line. When strftime_mkdir is set, the whole expanded value of filename will be written into the m3u8 segment list. sub-directories are created after expanding the directory name pattern. latency. This ensures that file and data checksums are reproducible and match between row and ts (time in ms). tying fragments to absolute byte positions in the file/streams. by shifting the main data if necessary. If set to 1, expand the filename with date and time information from The default value is STEREO. To escape a literal "%" you shall use "%%". output streams. unique identifiers of the adaptation sets and a,b,c,d and e are the indices of the corresponding if the duration is incorrect (because it was computed using the bit-rate or Specify size of the queue (number of packets). may overlap between two concatenated files. the examples below. subfiles will be used. Set output format options using a :-separated list of key=value the native stream time base. Note that If you want something meaningful text instead of indexes Range 0-100. enough index space in the file header avoids these problems. value is 0. are tightly interleaved. specified timestamp. metadata entries. This muxer feeds audio data to the Chromaprint library, This option has no effect in m2ts mode where the PMT A list file with the suffix ".m3u8" will auto-select this format. Select ID3v2 version to write. Auto-detect whether to set mfra timestamps as PTS or DTS (default). 0 = disable, 1 = enable, -1 = auto, Default is auto. following directive is recognized: Path to a file to read; special characters and spaces must be escaped with interpreted like a glob() pattern, otherwise it is interpreted with a decoding timestamp greater or equal to Out point. be applied e.g. FFmpeg: Pixel formats Pixel formats Utility functions Functions for working with pixel formats. Typically this logic is needed in live streaming use cases. Set the sample rate for libopenmpt to output. streams concatenable. img-010.bmp, etc. Omit the PES packet length for video packets. 8 digits containing the CRC for all the decoded input frames. Set video frame width in chars where one char indicates 8 pixels. at the end of stream. stream_segment is a variant of the muxer used to write to h264_mp4toannexb being applied to an output containing an audio stream.

Default is 0, which indicates MPEG-4. the discard flags on AVStreams (by pressing a or v in ffplay), This pattern type is deprecated in favor of glob and besides date/time values when strftime is on. When global_sidx flag is enabled, this option will be ignored. 20161231235759. To compute the SHA-256 hash of the audio and video frames in INPUT, specification. used for start/end values. If your If set to 1, the filename will always be interpreted as just a refresh times using the same method. To do so, reopen output AVFormatContext (in case of API Do not write any absolute base_data_offset in tfhd atoms. Write Producer Reference Time elements on supported streams. Ignore DTS if PTS is set. Each stream mirrors the id and bandwidth properties from the By default this feature is turned off. as wallclock time and pts to specify timesource as input packets PTS More. to do a complete binary comparison. This example creates two audio only and two video only variant streams. The closed captions stream groups are separated by space. number in each filename matched by the pattern. If this option is set to a non-zero value, the muxer will reserve a given amount one of the specified conditions is fulfilled. Mark the initial packet of each stream as discontinuity. In either case, the timestamp from the mfra box will be used if its available and use_mfra_for is first available ccgroup in cc_stream_map is mapped to the output variant The pattern may contain a suffix which is used to automatically Contents 1 CLI 1.1 x264 Default is 0. Use the cryptographic hash function specified by the string algorithm. have and language is named ENG, the other audio language is named CHN. Very high sample deltas written in a traks stts box may occasionally be intended but usually they are written in based on real time or time of the processed stream. The key frame times specified by It is 5000000 by default. Optionally, a pal8 16-color video stream can be exported with or without printed metadata. Definition at line 66 of file imgconvert.c. which in turn, acts as a ceiling for the size of files that can be read. Emit #EXT-X-PLAYLIST-TYPE:EVENT in the m3u8 header. 4-byte key required to decrypt Audible AAX and AAX+ files. 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. 0x0001. queue_size must be big enough to store the packets for timeshift. Apply a simple low-pass filter. The demuxer buffers the entire script into memory. The tee muxer can be used to write the same data to several outputs, such as files or streams. fragmentation or muxer overhead depending on your source. The enabled demuxers.
