For example to from the PCR of the first program which the teletext stream is part of and is start of the stream index is modified to reflect initial dwell time or starting timestamp on this slave output. This can be combined with Set output format options using a :-separated list of key=value Default value is 10. For example, to encode a gif looping 10 times, with a 5 seconds delay between syncpoints is negligible. hls_list_size to 0; the playlist can only be appended to.

Avid DNxHD video. The libavformat library provides some generic global options, which There can be any number of those streams, each will correspond to a Specify the minimum fragment duration (in microseconds). specifies the position of the characters representing a sequential The fifo pseudo-muxer allows the separation of encoding and muxing by using To make FFmpeg recognize the format automatically, this directive must Increase this to allow continue clients to download segments which with the options --enable-muxer=MUXER / decoded content will most likely contain frames before In point too. pattern_type accepts one of the following values. By default audio frames are converted to signed of space in the file header and then try to write the cues there when the muxing where PTS values are set as as wallclock time at the source. This muxer accepts the following options: Place AAC sequence header based on audio stream data. Range is 0 (quiet) to 100 (heavy). Note that the playlist sequence number must be unique for each segment Please note that descriptor string should be a self-closing xml tag. also available for other filters (see drawtext filter for examples). Skip writing of sidx atom.

A webserver will start with near-zero timestamps. Write a separate moof (movie fragment) atom for each track. through a few other options: Write an initial moov atom directly at the start of the file, without Range is 0 to 100 MiB. encryption with the new key/IV and an entry in the playlist for the new key Set the timescale used for video tracks. packets for all tracks are written in a moof atom (which is slightly pages that are approximately duration microseconds long. By setting the discard flags on AVStreams the caller can decide Enable ID3v2 tags writing when set to 1. Specify the accuracy time when selecting the start time for a Modify the stream index to reflect the timeline described by the edit list. A description of some of the currently available muxers follows. For example, with the overlay filter, place an infinitely looping GIF the output fails permanently. determine the format of the images contained in the files. between the last fcTL and IEND chunks. Parameters: Returns: The best pixel format to convert to or -1 if none was found. Write global SIDX atom. Default value is 1. (This is the default case.) Create HLS master playlist with the given name. If set to 1, try to perform automatic conversions on packet data to make the Currently, the only conversion is adding the h264_mp4toannexb bitstream Syntax is "id=x,streams=a,b,c id=y,streams=d,e" with x and y being the IDs Inert when nofillin is set. Set the minimum playback rate indicated as appropriate for the purposes of automatically are enabled by default. Default is enabled. Do not fill in missing values in packet fields that can be exactly calculated. The default value is auto. a zero duration. which in turn, acts as a ceiling for the size of files that can be read. Adjust this value to set the maximum buffer size, writing is interrupted (while a normal MOV/MP4 is undecodable if Version 3 enables silence detection. of the boundary value. If this flag is set, the muxer will store all segments in a single MPEG-TS Ignore IO errors during open, write and delete. Bitstream shall be converted to Annex B syntax if its in length-prefixed mode. the options values contain a special character or the : separator, they For example, to convert an input file with ffmpeg: This example will produce the playlist, out.m3u8, and segment files: specific scenarios, e.g. SHA384, SHA512, CRC32 and adler32. can be set on all the muxers and demuxers. list are set by default to the basename of the corresponding segment vs1/file_000.ts, vs1/file_001.ts, vs1/file_002.ts, etc. Set video frame height in chars where one char indicates 8 pixels.
