static double val(void *priv, double ch)
Libavcodec external API header.
#define AV_EF_EXPLODE
abort decoding on minor error detection
#define u(width, name, range_min, range_max)
common internal and external API header
#define AV_CODEC_CAP_DR1
Codec uses get_buffer() or get_encode_buffer() for allocating buffers and supports custom allocators.
#define AV_CODEC_CAP_SLICE_THREADS
Codec supports slice-based (or partition-based) multithreading.
#define AV_CODEC_CAP_FRAME_THREADS
Codec supports frame-level multithreading.
#define AVERROR_INVALIDDATA
Invalid data found when processing input.
#define AV_LOG_WARNING
Something somehow does not look correct.
#define AV_LOG_ERROR
Something went wrong and cannot losslessly be recovered.
@ AV_PICTURE_TYPE_I
Intra.
common internal API header
#define NULL_IF_CONFIG_SMALL(x)
Return NULL if CONFIG_SMALL is true, otherwise the argument without modification.
static int slice_end(AVCodecContext *avctx, AVFrame *pict)
Handle slice ends.
#define AV_PIX_FMT_YUV444P10
FF_ENABLE_DEPRECATION_WARNINGS int ff_thread_get_buffer(AVCodecContext *avctx, ThreadFrame *f, int flags)
Wrapper around get_buffer() for frame-multithreaded codecs.
main external API structure.
enum AVPixelFormat pix_fmt
Pixel format, see AV_PIX_FMT_xxx.
int width
picture width / height.
int bits_per_raw_sample
Bits per sample/pixel of internal libavcodec pixel/sample format.
int thread_count
thread count is used to decide how many independent tasks should be passed to execute()
int(* execute2)(struct AVCodecContext *c, int(*func)(struct AVCodecContext *c2, void *arg, int jobnr, int threadnr), void *arg2, int *ret, int count)
The codec may call this to execute several independent things.
int err_recognition
Error recognition; may misdetect some more or less valid parts as errors.
const char * name
Name of the codec implementation.
This structure describes decoded (raw) audio or video data.
uint8_t * data[AV_NUM_DATA_POINTERS]
pointer to the picture/channel planes.
int key_frame
1 -> keyframe, 0-> not
int linesize[AV_NUM_DATA_POINTERS]
For video, size in bytes of each picture line.
enum AVPictureType pict_type
Picture type of the frame.
This structure stores compressed data.
Used for passing data between threads.
