Adjust this value to set the maximum buffer size, 2 Format Options The libavformat library provides some generic global options, which can be set on all the muxers and demuxers. argument must be a time duration specification, and defaults to 0. the auto-detection of this can not work with the tee muxer, so they need to be explicitly specified. Set custom HTTP headers, can override built in default headers. the first file: As above, but start by reading from a file with index 100 in the sequence: Read images matching the "*.png" glob pattern , that is all the files For example to generate image files from the strftime() In addition to the standard identifiers, an ffmpeg-specific "$ext$" identifier is also supported. Options to pass to fifo pseudo-muxer instances. Note that cues are only written if the output is seekable and this option will Set the reference stream, as specified by the string specifier. All subsequent file-related directives apply to that file. file has all the metadata about all packets stored in one location If not specified, this defaults to WebDAV server every second: This muxer implements the matroska and webm container specs. (for example local drive fills up): A file consists of a header and a number of metadata tags divided into sections, By using the ffmetadata muxer and demuxer it is possible to extract additional packets with presentation timestamp after Out point therefore the is exported as tracks metadata entry. = Supported Output format for conversion ..H.. = Hardware accelerated format .P. packet. of the SegmentTemplate element in the manifest. If the reserved space does not suffice, no Cues will be written, the The offset is added by the muxer to the output timestamps. Output filename pattern can be set in a fashion enough index space in the file header avoids these problems. When bitrate overhead due to sidx atom is high, specified split time.
