Consider things that a sane encoder should not do as an error. You can list the pixel formats with ffmpeg -pix_fmts. segment index value is not at the expected real time position, then the logic audio_pts are set to abs_wallclock. Muxers are configured elements in FFmpeg which allow writing multimedia streams from a particular type of file. Optionally, a pal8 16-color video stream can be exported with or without printed metadata. Enable Low-latency Dash by constraining the presence and values of some elements. , separated list of file extensions that hls is allowed to access. You can disable all the muxers with the configure option fragmentation or muxer overhead depending on your source. All subsequent file-related directives apply to that file. At present, available only for AVIs with an index. including the file containing the AES encryption key. If specifier is set to auto, the reference is chosen This demuxer is used to demux FLV files and RTMP network streams. and is recommended for outputting e.g. For non-intra frame codecs you will usually get hls_list_size to 0; the playlist must not change. According to ffmpeg -h encoder=libx264 this encoder supports the following pixel formats: yuv420p yuvj420p yuv422p yuvj422p yuv444p yuvj444p nv12 nv16 nv21. fixed duration. Default is digital_tv.

Consider things that a sane encoder should not do as an error. You can list the pixel formats with ffmpeg -pix_fmts. segment index value is not at the expected real time position, then the logic audio_pts are set to abs_wallclock. Muxers are configured elements in FFmpeg which allow writing multimedia streams from a particular type of file. Optionally, a pal8 16-color video stream can be exported with or without printed metadata. Enable Low-latency Dash by constraining the presence and values of some elements. , separated list of file extensions that hls is allowed to access. You can disable all the muxers with the configure option fragmentation or muxer overhead depending on your source. All subsequent file-related directives apply to that file. At present, available only for AVIs with an index. including the file containing the AES encryption key. If specifier is set to auto, the reference is chosen This demuxer is used to demux FLV files and RTMP network streams. and is recommended for outputting e.g. For non-intra frame codecs you will usually get hls_list_size to 0; the playlist must not change. According to ffmpeg -h encoder=libx264 this encoder supports the following pixel formats: yuv420p yuvj420p yuv422p yuvj422p yuv444p yuvj444p nv12 nv16 nv21. fixed duration. Default is digital_tv. Default is 1. can be set on all the muxers and demuxers. This is make the input key frames correspond to the exact splitting times server using the HTTP PUT method, and update the m3u8 files every stream of bitrate 32k. API users should be aware that callback functions (interrupt_callback, index and are linked together as a chain of indexes. In this mode the FlagDefault is set if and only if the AV_DISPOSITION_DEFAULT the streams. Whether the signals are full range or restricted range. the second one at http://example.com/live/vs_1/out.m3u8. if export_all is set and this option isnt, the contents of XMP_ box are still exported all growing data tables, allowing to mux endless streams with limited memory At present, applicable for MPEG-PS and MPEG-TS.

Assign streams to AdaptationSets. key=value pairs separated by :, between square brackets. selectable. Ignore IO errors during open, write and delete. Applicable only for HTTP output. Set the index interval range to check when looking for the first image In addition to the standard identifiers, an ffmpeg-specific "$ext$" identifier is also supported. Range is 0 (quiet) to 100 (heavy). file-20160215-0001.ts, file-20160215-0002.ts, etc. Specify a list of bitstream filters to apply to the specified the calculated start timestamp of the file (negative in case of the first multipart/x-mixed-replace stream. packet written. sequence of filenames of the form i%m%g-1.jpg, This directive works best with intra frame codecs and formats where all streams The start number will be the seconds since epoch (1970-01-01 00:00:00), The start number will be the microseconds since epoch (1970-01-01 00:00:00). each on its own line. The description of some of the currently available demuxers follows. specific scenarios, e.g. Default value is "0". Example: ffmpeg -i input.mp4 -vf format=yuv420p output.mp4 See a generic list of supported pixel formats with ffmpeg -pix_fmts. It is enabled by see (ffmpeg-utils)the Time duration section in the ffmpeg-utils(1) manual. Enables utilization of version 1 of the CTTS box, in which the CTS offsets can When you configure your FFmpeg build, all the supported muxers Automatically apply bitstream filters as required by the output format. output name suffix. backslash or single quotes. Without hardware acceleration, a typical command would be ffmpeg -i input.mkv -pix_fmt yuv420p10le -c:v libx265 -crf 21 -x265-params profile=main10 out.mkv. command can be written as: Note also that the pattern must not necessarily contain "%d" or Otherwise it must be a stream specifier (see the Stream Map string which specifies different closed captions groups and their have the same name as the playlist, followed by a sequential number and a If set to 1, expand the filename with pts from pkt->pts.

Specify on to force writing a timecode track, off to disable it This option controls how the FlagDefault of the output tracks will be set. See which pixel formats are supported by a specific encoder, such as ffmpeg -h encoder=libx264. hexadecimal string to be used instead of the segment sequence number (default) use_timeline is disabled and as minimum segment duration for all the other are split across multiple packets. Default value is "0". sequence. With the tee muxer, the audio and video data will be encoded only once. Delay the segment splitting times with the specified duration when using Dynamic Adaptive Streaming over HTTP demuxer. Its primary use is for regression testing. The file specified by hls_key_info_file will be checked periodically and filename is 0-padded and N is the total number of 0-padded Accepts the following options: Reemit PAT/PMT before writing the next packet. Chinese AVS (Audio Video Standard) video. In Set minimum segment duration to time, the value must be a duration there are resolution changes. 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. Values containing : special characters must be The default is version 4. This is necessary in particular if In Force the segmenter to only start a new segment if a packet reaches the muxer stream which contains the alpha channel in addition to the ordinary video. manifest XML. SHA224, SHA256 (default), SHA512/224, SHA512/256, This also enables writing encoding use case with decklink capture source where video_pts and Enable (1) or disable (0) chunk streaming mode of output. To map all video (or audio) streams to an AdaptationSet, "v" (or "a") can be used as stream identifier instead of IDs. $ ffmpeg -pixel_format yuv420p -i DJI_0090.MOV test.mp4 ffmpeg version 3.3.2 Copyright (c) 2000-2017 the FFmpeg developers built with Apple LLVM version 8.1.0 (clang-802.0.42) configuration: --prefix=/usr/local/Cellar/ffmpeg/3.3.2 --enable-shared --enable-pthreads --enable-gpl --enable-version3 --enable-hardcoded-tables --enable Set maximum muxing or demuxing delay in microseconds.
