gstgl.glmemory

Module for [GLMemory] class

Types 1

GstGLMemory is a #GstGLBaseMemory subclass providing support for the mapping of OpenGL textures.

#GstGLMemory is created or wrapped through [gstgl.glbase_memory.GLBaseMemory.alloc] with #GstGLVideoAllocationParams.

Data is uploaded or downloaded from the GPU as is necessary.

The #GstCaps that is used for #GstGLMemory based buffers should contain the [gstgl.types.CAPS_FEATURE_MEMORY_GL_MEMORY] as a #GstCapsFeatures and should contain a 'texture-target' field with one of the #GstGLTextureTarget values as a string, i.e. some combination of 'texture-target=(string){2D, rectangle, external-oes}'.

void texFormat(gstgl.types.GLFormat propval) @propertySet `texFormat` field. Params: propval = the texture type

gstvideo.video_info.VideoInfo info() @propertyGet `info` field. Returns: the texture's #GstVideoInfo

gstvideo.video_alignment.VideoAlignment valign() @propertyGet `valign` field. Returns: data alignment for system memory mapping

void valign(gstvideo.video_alignment.VideoAlignment propval) @propertySet `valign` field. Params: propval = data alignment for system memory mapping

uint plane() @propertyGet `plane` field. Returns: data plane in @info

void plane(uint propval) @propertySet `plane` field. Params: propval = data plane in @info

bool textureWrapped() @property

void textureWrapped(bool propval) @property

uint unpackLength() @property

void unpackLength(uint propval) @property

uint texWidth() @property

void texWidth(uint propval) @property

bool copyInto(uint  texId,  gstgl.types.GLTextureTarget target,  gstgl.types.GLFormat texFormat,  int  width,  int  height)

Copies glmem into the texture specified by texid. The format of texid is specified by texformat, width and height.

bool copyTeximage(uint  texId,  gstgl.types.GLTextureTarget outTarget,  gstgl.types.GLFormat outTexFormat,  int  outWidth,  int  outHeight)

Copies the texture in #GstGLMemory into the texture specified by texid, outtarget, outtexformat, outwidth and outheight.

gstgl.types.GLFormat getTextureFormat()

int getTextureHeight()

uint getTextureId()

gstgl.types.GLTextureTarget getTextureTarget()

int getTextureWidth()

void init_(gst.allocator.Allocator allocator,  gst.memory.Memory parent,  gstgl.glcontext.GLContext context,  gstgl.types.GLTextureTarget target,  gstgl.types.GLFormat texFormat,  gst.allocation_params.AllocationParams params,  gstvideo.video_info.VideoInfo info,  uint  plane,  gstvideo.video_alignment.VideoAlignment valign,  void *  userData =  null,  glib.types.DestroyNotify notify =  null)

Initializes mem with the required parameters. info is assumed to have already have been modified with [gstvideo.videoinfo.VideoInfo.align].

bool readPixels(void * writePointer = null)Reads the texture in #GstGLMemory into writepointer if no buffer is bound to `GLPIXELPACKBUFFER`. Otherwise writepointer is the byte offset into the currently bound `GLPIXELPACKBUFFER` buffer to s...

void texsubimage(void * readPointer = null)Reads the texture in readpointer into glmem.

void initOnce()Initializes the GL Base Texture allocator. It is safe to call this function multiple times. This must be called before any other GstGLMemory operation.
