        Constant Field Values

      • codec

        private java.lang.String codec
        The codec name for the encoding process. If null or not specified the encoder will perform a direct stream copy.

      • tag

        private java.lang.String tag
        The the forced tag/fourcc value for the video stream.

      • bitRate

        private java.lang.Integer bitRate
        The bitrate value for the encoding process. If null or not specified a default value will be picked.

      • frameRate

        private java.lang.Integer frameRate
        The frame rate value for the encoding process. If null or not specified a default value will be picked.

      • size

        private VideoSize size
        The video size for the encoding process. If null or not specified the source video size will not be modified.

      • quality

        private java.lang.Integer quality
        The audio quality value for the encoding process. If null or not specified the ffmpeg default will be used

      • pixelFormat

        private java.lang.String pixelFormat

      • complexFiltergraph

        private FilterGraph complexFiltergraph

      • videoFilters

        private final java.util.ArrayList<VideoFilter> videoFilters

        private boolean faststart
        Encode the video with faststart mode, default OFF

        The mov/mp4/ismv muxer supports fragmentation. Normally, a MOV/MP4 file has all the metadata about all packets stored in one location (written at the end of the file, it can be moved to the start for better playback by adding faststart to the movflags, or using the qt-faststart tool). A fragmented file consists of a number of fragments, where packets and metadata about these packets are stored together. Writing a fragmented file has the advantage that the file is decodable even if the writing is interrupted (while a normal MOV/MP4 is undecodable if it is not properly finished), and it requires less memory when writing very long files (since writing normal MOV/MP4 files stores info about every single packet in memory until the file is closed). The downside is that it is less compatible with other applications.

      • crf

        private java.lang.Integer crf
        Set the quality for constant quality mode. The lower the value, the better the quality and the larger the file size. Reference Range:[0, 51]

      • preset

        private java.lang.String preset
        This option itemizes a range of choices from ultrafast (best speed) to placebo (best quality). PresetEnum
