    • DIRECT_STREAM_COPY

      public static final String DIRECT_STREAM_COPY
      This value can be set in the codec field to perform a direct stream copy, without re-encoding of the audio stream.
      See Also:

    • codec

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

    • tag

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

    • bitRate

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

    • frameRate

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

    • pixelFormat

      private String pixelFormat

    • vsync

      private VsyncMethod vsync

    • complexFiltergraph

      private FilterGraph complexFiltergraph

    • videoFilters

      private final ArrayList<VideoFilter> videoFilters

    • faststart

      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.

    • tune

      private TuneEnum tune

    • x264Profile

      private X264_PROFILE x264Profile

    • crf

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