  • Field Details

    • BUFFER_POOL_OPTION_VIDEO_AFFINE_TRANSFORMATION_META

      public static final String BUFFER_POOL_OPTION_VIDEO_AFFINE_TRANSFORMATION_META
      See Also:

    • BUFFER_POOL_OPTION_VIDEO_ALIGNMENT

      public static final String BUFFER_POOL_OPTION_VIDEO_ALIGNMENT

      A bufferpool option to enable extra padding. When a bufferpool supports this option, gst_buffer_pool_config_set_video_alignment() can be called.

      When this option is enabled on the bufferpool, GST_BUFFER_POOL_OPTION_VIDEO_META should also be enabled.

      See Also:

    • BUFFER_POOL_OPTION_VIDEO_GL_TEXTURE_UPLOAD_META

      public static final String BUFFER_POOL_OPTION_VIDEO_GL_TEXTURE_UPLOAD_META

      An option that can be activated on a bufferpool to request gl texture upload meta on buffers from the pool.

      When this option is enabled on the bufferpool, GSTBUFFERPOOLOPTIONVIDEOMETA should also be enabled.

    • CAPS_FEATURE_FORMAT_INTERLACED

      public static final String CAPS_FEATURE_FORMAT_INTERLACED

      Name of the caps feature indicating that the stream is interlaced.

      Currently it is only used for video with 'interlace-mode=alternate' to ensure backwards compatibility for this new mode. In this mode each buffer carries a single field of interlaced video. GSTVIDEOBUFFERFLAGTOPFIELD and GSTVIDEOBUFFERFLAGBOTTOMFIELD indicate whether the buffer carries a top or bottom field. The order of buffers/fields in the stream and the timestamps on the buffers indicate the temporal order of the fields. Top and bottom fields are expected to alternate in this mode. The frame rate in the caps still signals the frame rate, so the notional field rate will be twice the frame rate from the caps (see GSTVIDEOINFOFIELDRATEN).

      Since:
      1.16.

    • videoGuessFramerate

      public static boolean videoGuessFramerate(ClockTime duration, @Nullable Out<Integer> destN, @Nullable Out<Integer> destD)

      Given the nominal duration of one video frame, this function will check some standard framerates for a close match (within 0.1%) and return one if possible,

      It will calculate an arbitrary framerate if no close match was found, and return false.

      It returns false if a duration of 0 is passed.

      Parameters:
      duration - Nominal duration of one frame
      destN - Numerator of the calculated framerate
      destD - Denominator of the calculated framerate
      Returns:
      true if a close "standard" framerate was recognised, and false otherwise.
      Since:
      1.6

      Parameters:
      width - Width of the video frame
      height - Height of the video frame
      parN - Pixel aspect ratio numerator
      parD - Pixel aspect ratio denominator
