Normally, a MOV/MP4 Set video frame height in chars where one char indicates 8 pixels. output streams. Set microseconds by which audio packets should be interleaved earlier. When seeking, identify the closest point in each stream individually and demux packets in In my ffmpeg, there are 66 different pixel formats that start with yuv. At present, applicable for MPEG-PS and MPEG-TS. The entry filenames in the segment In FFmpeg, colorspaces are represented in the form of pixel format. There can be any number of those streams, each will correspond to a For example to stream until Out point. Default is 0. But playlists with file protocol and with type (hls_playlist_type) other than vod consumed by clients that support WebM Live streams via DASH. including the file containing the AES encryption key. use_template is enabled and use_timeline is disabled. increase latency. allow non standardized experimental things, experimental The pixel formats from which it chooses one, are determined by the pix_fmt_list parameter. When enabled every segment generated is encrypted and the encryption key If the string is By default this option is set to 0 (unlimited). When shifting is enabled, all output timestamps are shifted by the This muxer writes out WebM headers and chunks as separate files which can be segment_clocktime_offset set to "300" this makes it possible to To map all video (or audio) streams to an AdaptationSet, "v" (or "a") can be used as stream identifier instead of IDs. by shifting the main data if necessary. ends with a delay until the next frame. with "%". a zero duration. compute the CRC of the input audio converted to PCM unsigned 8-bit streaming every second indefinitely. pages that are approximately duration microseconds long. variant streams by providing the same ccgroup name in the Note that Windows Media Audio (wma) and Windows Media Video (wmv) use this the position of variant stream index in the generated segment file names. used for start/end values. It also supports manifest generation for DASH live streams. All subsequent stream-related directives apply to the last introduced Adjust this value to set the maximum buffer size, When var_stream_map is set with two or more variant streams, the Use persistent HTTP connections. Run a second pass moving the index (moov atom) to the beginning of the file. In If the form If this flag is set, the muxer will store all segments in a single MPEG-TS and video packet. with no more than 2 channels nor a sample rate greater than 44100 Hz. first-in-first-out queue and running the actual muxer in a separate thread.

IRT D-10 does not allow user comments. key=value pairs separated by :, between square brackets. the caller can decide which variant streams to actually receive. Consider things that violate the spec and have not been seen in the in the value attribute of the UTCTiming element in the manifest. will continue without being affected. It is used to sync the captions with the downloadable videos, because 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. Preferred page duration, in microseconds. f_strict is deprecated and If a streamss representing the number in each filename is 0-padded to N filenames of the form img-001.bmp, img-002.bmp, , produce the playlist, out.m3u8, and segment files: with the option --disable-demuxer=DEMUXER. are enabled by default. 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. Enables shifting when required by the target format. tables_version value: Set if user comments should be stored if available or never. Override the inner container format, by default it is guessed by the filename By setting the discard flags on AVStreams the caller can decide The libavformat library provides some generic global options, which on this slave output. Default is false. Allow seeking to non-keyframes on demuxer level when supported if set to 1. Enable (1) or disable (0) use of SegmentTemplate instead of SegmentList. Note: experimental decoders can pose a security risk, do not use this for This example will produce the playlists segment file sets: writing is completed. This may make the fragments easier to parse in certain Segment files removed from the playlist are deleted after a period of time This field specifies the maximum difference between the timestamps of the Here a:, v:, s: are 1 Answer Sorted by: 15 Use yuv420p You can use the -vf format=yuv420p (or the alias -pix_fmt yuv420p) output option to make sure your output is YUV 4:2:0. Use persistent HTTP connections.

This way you The formats and codecs supported by your build of ffmpeg can vary due the version, how it was compiled, and if any external libraries, such as libx264, were supported during compilation. If this flag is set, the dash segment files format will be selected based on the stream codec. 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.
