5cb4f1a127 vsrc_buffer: return EAGAIN if no frame is available.
This is not an erroneous condition, do not print a warning.

e1d9dbf2d4 lavfi: add a new function av_buffersrc_buffer().
It can be used to directly pass a AVFilterBufferRef to lavfi, avoiding a
memcpy.

f7053dc41a vsrc_buffer: tweak error message in init()
Change:
Expected 7 arguments, but only %d found in '%s'\n
to:
Expected 7 arguments, but %d found in '%s'\n

as the user may provide more than 7 arguments, in that case the error
is not misleading.

737eb5976f Merge libavcore into libavutil
It is pretty hopeless that other considerable projects will adopt
libavutil alone in other projects. Projects that need small footprint
are better off with more specialized libraries such as gnulib or rather
just copy the necessary parts that they need. With this in mind, nobody
is helped by having libavutil and libavcore split. In order to ease
maintenance inside and around FFmpeg and to reduce confusion where to
put common code, avcore's functionality is merged (back) to avutil.

data, required by audio filtering integration.

cc80caff52 Separate video specific BufferRef properties into VideoProps.
Define a new struct AVFilterBufferRefVideoProps and add a type field
to AVFilterBufferRef.

Video specific properties in AVFilterBufferRefVideoProps are now
referred to by *video pointer in AVFilterBufferRef.

avfilter_copy_picref_props -> avfilter_copy_buffer_ref_props
AVFilterBufferRef.pic      -> AVFilterBufferRef.buffer

They have been renamed to allow sharing with audio.

well, and the new name is more generic.
