Method Details

getDeviceIdToUse

default int getDeviceIdToUse()

Returns:

-1 by default

addHardwareNVScalerFilter

default void addHardwareNVScalerFilter(Point newSize,
 String pixelFormat,
 String interpAlgo)

Not checks will be done NVIDIA Performance Primitives via libnpp. Via -vf ffmpeg's option.

Parameters:

newSize - like 1280x720 or -1x720

pixelFormat - can be null (== same) or nv12, yuv444p16...

interpAlgo - can be null or nn (Nearest neighbour), linear (2-parameter cubic (B=1, C=0)), cubic2p_catmullrom (2-parameter cubic (B=0, C=1/2)), cubic2p_b05c03 (2-parameter cubic (B=1/2, C=3/10)), super (Supersampling), lanczos ...

addHardwareNVMultipleScalerFilterComplex

default void addHardwareNVMultipleScalerFilterComplex(Map<String,String> configuration)

Use nvresize Not checks will be done

Parameters:

configuration - resolution -> filter out name ; resolution can be litteral like hd1080 or cif and filter out name can be "out0", usable after with "-map [out0] -vcodec xxx out.ext"

addHardwareVideoDecoding

default void addHardwareVideoDecoding(String source,
 FFprobeJAXB analysingResult,
 FFHardwareCodec hardwareCodec,
 FFAbout about)
                               throws MediaException

"Patch" ffmpeg command line for hardware decoding. Only first video stream will be decoded. Hardware decoding often works in tandem with hardware coding.

Throws:

MediaException - if hardware decoding is not possible.

addHardwareVideoEncoding

default void addHardwareVideoEncoding(String destCodecName,
 int outputVideoStreamIndex,
 FFHardwareCodec hardwareCodec,
 FFAbout about)
                               throws MediaException

Set codec name, and if it possible, use hardware encoding.

Parameters:

outputVideoStreamIndex - (-1 by default), X -> -c:v:X

Throws:

MediaException
