Detailed Description

common internal api header.

Definition in file internal.h.

Macro Definition Documentation

◆ FF_CODEC_CAP_INIT_THREADSAFE

#define FF_CODEC_CAP_INIT_THREADSAFE (1 << 0)

The codec does not modify any global variables in the init function, allowing to call the init function without locking any global mutexes.

Definition at line 42 of file internal.h.

◆ FF_CODEC_CAP_INIT_CLEANUP

#define FF_CODEC_CAP_INIT_CLEANUP (1 << 1)

The codec allows calling the close function for deallocation even if the init function returned a failure.

Without this capability flag, a codec does such cleanup internally when returning failures from the init function and does not expect the close function to be called at all.

Definition at line 50 of file internal.h.

◆ FF_CODEC_CAP_SETS_PKT_DTS

#define FF_CODEC_CAP_SETS_PKT_DTS (1 << 2)

Decoders marked with FF_CODEC_CAP_SETS_PKT_DTS want to set AVFrame.pkt_dts manually.

If the flag is set, decode.c won't overwrite this field. If it's unset, decode.c tries to guess the pkt_dts field from the input AVPacket.

Definition at line 57 of file internal.h.

◆ FF_CODEC_CAP_SKIP_FRAME_FILL_PARAM

#define FF_CODEC_CAP_SKIP_FRAME_FILL_PARAM (1 << 3)

The decoder extracts and fills its parameters even if the frame is skipped due to the skip_frame setting.

Definition at line 62 of file internal.h.

◆ FF_CODEC_CAP_EXPORTS_CROPPING

#define FF_CODEC_CAP_EXPORTS_CROPPING (1 << 4)

The decoder sets the cropping fields in the output frames manually.

If this cap is set, the generic code will initialize output frame dimensions to coded rather than display values.

Definition at line 68 of file internal.h.

◆ FF_CODEC_CAP_SLICE_THREAD_HAS_MF

#define FF_CODEC_CAP_SLICE_THREAD_HAS_MF (1 << 5)

Codec initializes slice-based threading with a main function.

Definition at line 72 of file internal.h.

◆ FF_CODEC_CAP_ALLOCATE_PROGRESS

#define FF_CODEC_CAP_ALLOCATE_PROGRESS (1 << 6)

Definition at line 77 of file internal.h.

◆ FF_CODEC_CAP_AUTO_THREADS

#define FF_CODEC_CAP_AUTO_THREADS (1 << 7)

Codec handles avctx->thread_count == 0 (auto) internally.

Definition at line 81 of file internal.h.

◆ FF_CODEC_CAP_SETS_FRAME_PROPS

#define FF_CODEC_CAP_SETS_FRAME_PROPS (1 << 8)

Codec handles output frame properties internally instead of letting the internal logic derive them from AVCodecInternal.last_pkt_props.

Definition at line 86 of file internal.h.

◆ FF_CODEC_TAGS_END

#define FF_CODEC_TAGS_END -1

AVCodec.codec_tags termination value.

Definition at line 98 of file internal.h.

◆ FF_QSCALE_TYPE_VP56

#define FF_QSCALE_TYPE_VP56 3

Definition at line 99 of file internal.h.

◆ FF_SANE_NB_CHANNELS

#define FF_SANE_NB_CHANNELS 512U

Definition at line 101 of file internal.h.

◆ FF_SIGNBIT

#define FF_SIGNBIT ( x ) ((x) >> CHAR_BIT * sizeof(x) - 1)

Definition at line 103 of file internal.h.

◆ STRIDE_ALIGN

#define STRIDE_ALIGN 8

Definition at line 112 of file internal.h.

◆ FF_MAX_EXTRADATA_SIZE

#define FF_MAX_EXTRADATA_SIZE ((1 << 28) - AV_INPUT_BUFFER_PADDING_SIZE)

Maximum size in bytes of extradata.

This value was chosen such that every bit of the buffer is addressable by a 32-bit signed integer as used by get_bits.

Definition at line 237 of file internal.h.

◆ FF_REGET_BUFFER_FLAG_READONLY

#define FF_REGET_BUFFER_FLAG_READONLY 1

the returned buffer does not need to be writable

Definition at line 277 of file internal.h.

Check AVFrame for S12M timecode side data and allocate and fill TC SEI message with timecode info.

Parameters

frame	Raw frame to get S12M timecode side data from
rate	The frame rate
prefix_len	Number of bytes to allocate before SEI message
data	Pointer to a variable to store allocated memory Upon return the variable will hold NULL on error or if frame has no S12M timecode info. Otherwise it will point to prefix_len uninitialized bytes followed by *sei_size SEI message
sei_size	Pointer to a variable to store generated SEI message length

Returns: Zero on success, negative error code on failure
