Enum Constant Summary

Enum Constants
Enum Constant and Description
`AUTO_THREADS` Codec supports avctx->thread_count == 0 (auto).
`CHANNEL_CONF` Codec should fill in channel configuration and samplerate instead of container
`DELAY` Encoder or decoder requires flushing with NULL input at the end in order to give the complete and correct output.
`DR1` Codec uses get_buffer() for allocating buffers and supports custom allocators.
`DRAW_HORIZ_BAND` Decoder can use draw_horiz_band callback.
`EXPERIMENTAL` Codec is experimental and is thus avoided in favor of non experimental encoders
`FRAME_THREADS` Codec supports frame-level multithreading.
`HWACCEL` Codec can export data for HW decoding (XvMC).
`HWACCEL_VDPAU` Codec can export data for HW decoding (VDPAU).
`INTRA_ONLY` Codec is intra only.
`LOSSLESS` Codec is lossless.
`NEG_LINESIZES` Codec is able to deal with negative linesizes
`PARAM_CHANGE` Codec supports changed parameters at any point.
`SLICE_THREADS` Codec supports slice-based (or partition-based) multithreading.
`SMALL_LAST_FRAME` Codec can be fed a final frame with a smaller size.
`SUBFRAMES` Codec can output multiple frames per AVPacket Normally demuxers return one frame at a time, demuxers which do not do are connected to a parser to split what they return into proper frames.
`TRUNCATED`
`VARIABLE_FRAME_SIZE` Audio encoder supports receiving a different number of samples in each call.

- Enum Constant Detail
  - DRAW_HORIZ_BAND
```
public static final CodecCapability DRAW_HORIZ_BAND
```
    Decoder can use draw_horiz_band callback.
  - DR1
```
public static final CodecCapability DR1
```
    Codec uses get_buffer() for allocating buffers and supports custom allocators. If not set, it might not use get_buffer() at all or use operations that assume the buffer was allocated by avcodec_default_get_buffer.
  - TRUNCATED
```
public static final CodecCapability TRUNCATED
```
  - HWACCEL
```
public static final CodecCapability HWACCEL
```
    Codec can export data for HW decoding (XvMC).
  - DELAY
```
public static final CodecCapability DELAY
```
    Encoder or decoder requires flushing with NULL input at the end in order to give the complete and correct output. NOTE: If this flag is not set, the codec is guaranteed to never be fed with with NULL data. The user can still send NULL data to the public encode or decode function, but libavcodec will not pass it along to the codec unless this flag is set. Decoders: The decoder has a non-zero delay and needs to be fed with avpkt->data=NULL, avpkt->size=0 at the end to get the delayed data until the decoder no longer returns frames. Encoders: The encoder needs to be fed with NULL data at the end of encoding until the encoder no longer returns data. NOTE: Setting this flag also means that the encoder must set the pts and duration for each output packet. If this flag is not set, the pts and duration will be determined by libavcodec from the input frame.
  - SMALL_LAST_FRAME
```
public static final CodecCapability SMALL_LAST_FRAME
```
    Codec can be fed a final frame with a smaller size. This can be used to prevent truncation of the last audio samples.
  - HWACCEL_VDPAU
```
public static final CodecCapability HWACCEL_VDPAU
```
    Codec can export data for HW decoding (VDPAU).
  - SUBFRAMES
```
public static final CodecCapability SUBFRAMES
```
    Codec can output multiple frames per AVPacket Normally demuxers return one frame at a time, demuxers which do not do are connected to a parser to split what they return into proper frames. This flag is reserved to the very rare category of codecs which have a bitstream that cannot be split into frames without timeconsuming operations like full decoding. Demuxers carring such bitstreams thus may return multiple frames in a packet. This has many disadvantages like prohibiting stream copy in many cases thus it should only be considered as a last resort.
  - EXPERIMENTAL

public static final CodecCapability NEG_LINESIZES
```
    Codec is able to deal with negative linesizes
  - FRAME_THREADS
```
public static final CodecCapability FRAME_THREADS
```
    Codec supports frame-level multithreading.
  - SLICE_THREADS
```
public static final CodecCapability SLICE_THREADS
```
    Codec supports slice-based (or partition-based) multithreading.
  - PARAM_CHANGE
```
public static final CodecCapability PARAM_CHANGE
```
    Codec supports changed parameters at any point.
  - AUTO_THREADS
```
public static final CodecCapability AUTO_THREADS
```
    Codec supports avctx->thread_count == 0 (auto).
  - VARIABLE_FRAME_SIZE
```
public static final CodecCapability VARIABLE_FRAME_SIZE
```
    Audio encoder supports receiving a different number of samples in each call.
  - INTRA_ONLY
```
public static final CodecCapability INTRA_ONLY
```
    Codec is intra only.
  - LOSSLESS
```
public static final CodecCapability LOSSLESS
```
    Codec is lossless.
- Method Detail
  - values
```
public static CodecCapability[] values()
```
    Returns an array containing the constants of this enum type, in the order they are declared. This method may be used to iterate over the constants as follows:
```
for (CodecCapability c : CodecCapability.values())
    System.out.println(c);
```
    Returns:
    an array containing the constants of this enum type, in the order they are declared
  - valueOf
```
public static CodecCapability valueOf(String name)
```
    Returns the enum constant of this type with the specified name. The string must match exactly an identifier used to declare an enum constant in this type. (Extraneous whitespace characters are not permitted.)
    
    Parameters:
    name - the name of the enum constant to be returned.
    
    Returns:
    the enum constant with the specified name
    
    Throws:
    
    IllegalArgumentException - if this enum type has no constant with the specified name
    
    NullPointerException - if the argument is null
  - value
```
public final int value()
```
    Get the codec capability id defined in FFmpeg.
    
    Returns:
    FFmpeg codec capability id.
  - byId
```
public static CodecCapability byId(int id)
```
    Get a CodecCapability that matches to the specified FFmpeg id.
    
    Parameters:
    id - FFmpeg codec capability id.
    
    Returns:
    matching codec capability, or null if id is not defined.
