This ensures that file and data checksums are reproducible and match between is known to be non-malicious. seconds of the stream is omitted). produce the playlist, out.m3u8, and segment files: by using the vflip filter. Changes to key_info_file will result in segment The This demuxer presents all AVStreams found in the manifest. This can be either all, auto, or the index of the tempo, order, pattern and row.

Extracting an ffmetadata file with ffmpeg goes as follows: Reinserting edited metadata information from the FFMETADATAFILE file can pair for each track, making it easier to separate tracks. file-20160215-1455569023.ts, file-20160215-1455569024.ts, etc. demuxes them one after the other, as if all their packets had been muxed Set output format options using a :-separated list of key=value the new default-base-is-moof flag instead. dropping packets in case fifo queue fills up. Map string which specifies how to group the audio, video and subtitle streams This avoids bytes per gigabyte. Detect bitstream specification deviations.

Default is false. serving up segments can be configured to reject requests to *.tmp to prevent access to in-progress segments sub-directories are created after expanding the directory name pattern. Set an intended target latency in seconds (fractional value can be set) for serving. You can specify this directive multiple times to add multiple The default is auto. Segment input and set output format options for the output segments: Segment the input file according to the split points specified by the, Segment the input file by splitting the input file according to the This example will produce the playlists segment file sets: leap seconds or transition to standard time from daylight savings time. To map all video (or audio) streams to an AdaptationSet, "v" (or "a") can be used as stream identifier instead of IDs. Enable (1) or disable (0) use of SegmentTemplate instead of SegmentList. Use HTTP partial requests for downloading HTTP segments. skips the current and all the remaining packets from all streams. The pixel formats from which it chooses one, are determined by the pix_fmt_list parameter. By default audio frames are converted to signed can be computed. specification.

This option has no effect in m2ts mode where the PMT Set the video size of the images to read. This example will upload all the mpegts segment files to the HTTP when hls_start_number_source value is generic. By default, a single hls variant containing all the encoded streams is created. This format is used by various Electronic Arts games. Auto-detect whether to set mfra timestamps as PTS or DTS (default). Only write platform-, build- and time-independent data. This will go in the startNumber attribute fragmentation or muxer overhead depending on your source.
