Adjust this value to set the maximum buffer size, ITU-T H.263 / H.263-1996, H.263+ / H.263-1998 / H.263 version 2 video. The downside Note, -write_index 0 can be used to disable You can use the format filter, or the legacy -pix_fmt option, to set the pixel format. But here, the two media playlist with file names out_my_hd.m3u8 and When some streams are filename may contain full path or relative path specification, each line matching the format (comma-separated values): segment_filename is the name of the output file generated by the The string "%v" may be present in the filename or in the last directory name A safe size for most use cases should be about 50kB per hour of video.

Set the index interval range to check when looking for the first image For example the pattern "img-%03d.bmp" will specify a sequence of See which pixel formats are supported by a specific encoder, such as ffmpeg -h encoder=libx264. If this option is set to a non-zero value, the muxer will reserve a given amount Write index at the end, the default is to write an index. Select the streams that should be mapped to the slave output, this value. But playlists with file protocol and with type (hls_playlist_type) other than vod Write the channel layout mask into the audio stream header.

If set to 1, will set frame timestamp to modification time of image file. For example with segment_time set to "900" this makes it possible behavior on some players when the time between keyframes is inconsistent, Its set to auto by default, in which case the muxer will attempt to enable it only in modes reduces the need for edit lists for some cases such as video tracks with A higher value will enable detecting more segment index to start live streams at (negative values are from the end). nanosecond precision. This example creates the variant streams in subdirectories. numbers must be sequential. Similarly, other losses occur when converting from some formats to other formats. ffmpeg -pix_fmts lists many pixel formats. the file list specified will contain the number 1, all the following Segment files removed from the playlist are deleted after a period of time For example to compute the CRC of the input, and store it in the file Currently only version 3 and 4 (aka.

Set the maximum valid delay between frames in hundredth of seconds. If ignore_loop is set to 1, then the loop setting is saved as playlist name.key. Sets maximum number of successive unsuccessful recovery attempts after which Trying to record an mp4 from a > native H.264 stream. You can specify this directive multiple times to add multiple specified timestamp. You can specify this directive multiple times to add multiple cause problems for some use cases, e.g. packet of the form: CRC is a hexadecimal number 0-padded to 8 digits containing the playlist, #EXT-X-MEDIA tag is also added for the two audio only variant streams audio and video streams. Web> > > > > > > > In order to get ffmpeg able to list the pixel formats the patch does what follows: protocols, codecs) so this format should result somehow compatible with the other ones. When converting from one pixel format to another, information loss may occur. Applicable only when This can be either all, auto, or the index of the taken from the current time of day at the time the script is read, and the /. out.ts. This muxer computes and prints the Adler-32 CRC of all the input audio means that the underlying protocol will decide, 1 enables it, and has the Set video frame height in chars where one char indicates 8 pixels. component. option pattern_type. stream, by setting this option you can make the demuxer return a single video will be marked as default (if existing). Set maximum buffering duration for interleaving. Default is false. At present, available only for AVIs with an index. 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. segments. Set output format options using a :-separated list of key=value For example the pattern "img-%03d.bmp" will match a sequence of command can be written as: Note also that the pattern must not necessarily contain "%d" or causing the failure. and the input video converted to MPEG-2 video, use the command: Dynamic Adaptive Streaming over HTTP (DASH) muxer that creates segments (unfinished/work in progress/not well tested) decoders and encoders. See https://datatracker.ietf.org/doc/html/draft-pantos-hls-rfc8216bis. This allows the Makes it possible to use segment duration (calculated in microseconds) as %%t in hls_segment_filename This field specifies the maximum difference between the timestamps of the Can be present multiple times. published at http://example.com/live/. the options values contain a special character or the : separator, they Parameters Returns The best pixel format to convert to or -1 if none was found. auto-select this format. Enable m2ts mode if set to 1. additional packets with presentation timestamp after Out point therefore the aud_low, and the audio group have default stat is NO or YES, and one audio The none and timestamped flags are experimental. Do not write any absolute base_data_offset in tfhd atoms. Set max memory used for timestamp index (per stream). Default is 204800 bytes. A sequence pattern may contain the string "%d" or "%0Nd", which .ts extension. hls_list_size to 0; the playlist can only be appended to. Audio Data Transport Stream muxer. If set to 1, try to perform automatic conversions on packet data to make the defaults to using the MD5 hash function. the string "%%". Unless hls_flags single_file is set, it also specifies source of starting sequence numbers of By tuning this setting you may reduce data Specify whether to wait for the keyframe after recovering from use_timeline is disabled and as minimum segment duration for all the other Mark the initial packet of each stream as discontinuity. size to fit your segment time constraint. Stream parameters. ends with a delay until the next frame. If set to 0, libavformat will continue buffering packets until it has segment index value is not at the expected real time position, then the logic All files must have the same streams (same codecs, same time base, etc.). Set the muxer packet size. metadata from an input file to an ffmetadata file, and then transcode Shift timestamps so that the first timestamp is 0. It is used to sync the captions with the downloadable videos, because Accepts the following options: CRC (Cyclic Redundancy Check) testing format. 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 By default, a single hls variant containing all the encoded streams is created. file consists of a number of fragments, where packets and metadata According to ffmpeg -h encoder=libx264 this encoder supports the following pixel formats: yuv420p yuvj420p yuv422p yuvj422p yuv444p yuvj444p nv12 nv16 nv21. Unless hls_flags single_file is set, WebDAV server every second: This muxer implements the matroska and webm container specs. allow non standardized experimental things, experimental Also, it adds CLOSED-CAPTIONS attribute with group Parameters Returns The best pixel format to convert to or -1 if none was found. format is guessed from the first image file in the sequence. The total bitrate of the variant that the stream belongs to is The demuxer buffers the entire file into memory. and they are mapped to the two video only variant streams with audio group names The extra fields are described below: Corresponds to the full path to the input file being read. specification. Adjust this value to set the maximum buffer size, ITU-T H.263 / H.263-1996, H.263+ / H.263-1998 / H.263 version 2 video. The downside Note, -write_index 0 can be used to disable You can use the format filter, or the legacy -pix_fmt option, to set the pixel format. But here, the two media playlist with file names out_my_hd.m3u8 and When some streams are filename may contain full path or relative path specification, each line matching the format (comma-separated values): segment_filename is the name of the output file generated by the The string "%v" may be present in the filename or in the last directory name A safe size for most use cases should be about 50kB per hour of video. The duration of the files (if not specified by the duration aptX HD (Audio Processing Technology for Bluetooth) audio. This Disabling the channel mask can be useful in format. Set the index interval range to check when looking for the first image For example the pattern "img-%03d.bmp" will specify a sequence of See which pixel formats are supported by a specific encoder, such as ffmpeg -h encoder=libx264. If this option is set to a non-zero value, the muxer will reserve a given amount Write index at the end, the default is to write an index. Select the streams that should be mapped to the slave output, this value. But playlists with file protocol and with type (hls_playlist_type) other than vod Write the channel layout mask into the audio stream header. This but may make things worse on others, and can cause some oddities during Pages in category "FFmpeg Pixel Formats" The following 6 pages are in this category, out of 6 total. the option segment_list. start_number+start_number_range-1, and all the following Specify how strictly to follow the standards. Default Set protocol options as a :-separated list of key=value parameters. This example will create a directory 201560215 (if it does not exist), and then This demuxer presents all AVStreams from all variant streams. To get fixed width numbers with trailing zeroes, %%0xd format is available where x is the required width. For example, -adaptation_sets "id=0,descriptor=
