The new flags parameter allows to specify if the video ref to add
should overwrite the cache, if the flag is not set vsrc_buffer will
complain and abort; otherwise it will clean the already cached video
ref before to overwrite it, thus avoiding a leak.
|
|
Propagate av_vsrc_buffer_add_video_buffer_ref() error code rather than
return 0.
|
|
Also decrease the log level of the corresponding message to WARNING,
since the error is not fatal.
|
|
The new function is a wrapper around
av_vsrc_buffer_add_video_buffer_ref(), and allows to simplify the act
of pushing AVFrame data to the source buffer.
|
|
Avoid the need of two distinct av_vsrc_add_video_buffer_ref*
functions. Simplify the interface.
|
|
|
|
|
|
Rename av_vsrc_buffer_add_frame to
av_vsrc_buffer_add_video_buffer_ref(), and change its inteface to make
it accept in input an AVFilterBufferRef rather than an AVFrame.
This way the interface can be used without requiring the
inclusion/installation of libavcodec headers.

Now that pix_fmt, width, and height are directly embedded in the AVFrame,
there is no need to pass these values as separate arguments.
|
|
avfilter_copy_frame_props() avoids code duplication and increases
robustness.
The added files libavfilter/avcodec.[ch] are used for containing
utilities useful for gluing togheter libavfilter and libavcodec.
|
|
The format is a per-frame property, having it in AVFrame simplify the
operation of extraction of that information, since avoids the need to
access the codec/stream context.

Improve consistency with libavcodec.
This breaks libavfilter API/ABI.
The non-sequential 2.1.0 -> 2.4.0 bump is due to the mess previously
done with the lavfi minor number.
|
|
The sample aspect ratio is a per-frame property, so it makes sense to
define it in AVFrame rather than in the codec/stream context.
Simplify application-level sample aspect ratio information extraction,
and allow further simplifications.

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.

Done to keep ABI compatible. Otherwise this is just silly
|
|
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.

Define a new struct AVFilterBufferRefVideoProps and add a type field

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