Functions

func AvioClosep 

func AvioClosep(s unsafe.Pointer) int32

AvioClosep Close the resource accessed by the AVIOContext *s, free it and set the pointer pointing to it to NULL. This function can only be used if s was opened by avio_open(). The internal buffer is automatically flushed before closing the resource. /

type PixelFormat 

type PixelFormat int32

PixelFormat Pixel format. AV_PIX_FMT_RGB32 is handled in an endian-specific manner. An RGBA color is put together as: (A << 24) | (R << 16) | (G << 8) | B This is stored as BGRA on little-endian CPU architectures and ARGB on big-endian CPUs. If the resolution is not a multiple of the chroma subsampling factor then the chroma plane resolution must be rounded up. When the pixel format is palettized RGB32 (AV_PIX_FMT_PAL8), the palettized image data is stored in AVFrame.data[0]. The palette is transported in AVFrame.data[1], is 1024 bytes long (256 4-byte entries) and is formatted the same as in AV_PIX_FMT_RGB32 described above (i.e., it is also endian-specific). Note also that the individual RGB32 palette components stored in AVFrame.data[1] should be in the range 0..255. This is important as many custom PAL8 video codecs that were designed to run on the IBM VGA graphics adapter use 6-bit palette components. For all the 8 bits per pixel formats, an RGB32 palette is in data[1] like for pal8. This palette is filled in automatically by the function allocating the picture. /

type SampleFormat 

type SampleFormat int32

SampleFormat Audio sample formats - The data described by the sample format is always in native-endian order. Sample values can be expressed by native C types, hence the lack of a signed 24-bit sample format even though it is a common raw audio data format. - The floating-point formats are based on full volume being in the range [-1.0, 1.0]. Any values outside this range are beyond full volume level. - The data layout as used in av_samples_fill_arrays() and elsewhere in FFmpeg (such as AVFrame in libavcodec) is as follows: For planar sample formats, each audio channel is in a separate data plane, and linesize is the buffer size, in bytes, for a single plane. All data planes must be the same size. For packed sample formats, only the first data plane is used, and samples for each channel are interleaved. In this case, linesize is the buffer size, in bytes, for the 1 plane. /
