Hi.
i would like to post a google drive link containing some sample files regarding
a PS2 movie format.
this movie format goes by the name of IPU.
it's something of a "standard movie format" alongside PSS which is a modified
variant of MPEG-2 elementary stream designed for use on PS2 games.

If ff_codec_open2_recursive() fails, the already allocated
AVCodecContext leaks. Fix this by setting the FF_CODEC_CAP_INIT_CLEANUP
flag.

The init function of the ALAC encoder calls its own close function
if a call to ff_lpc_init() fails; yet nothing has been allocated before
that point (except extradata which is freed generically) and ff_lpc_init()
can be expected to clean up after itself on error (the documentation does
not say any
The decoder's close function simply presumed that some AVFrames have
been successfully allocated although this can of course fail.

Currently, every filter needs to provide code to transfer data from
AVFrame* to model input (DNNData*), and also from model output
(DNNData*) to AVFrame*. Actually, such transfer can be implemented
within DNN module, and so filter can focus on its own business logic.
DNN module also exports the fu
suppose we have a detect and classify filter in the future, the
detect filter generates some bounding boxes (BBox) as AVFrame sidedata,
and the classify filter executes DNN model for each BBox. For each
BBox, we need to crop the AVFrame, copy data to DNN model input and do
the model execution. So w
the userdata will be used for the interaction between AVFrame and DNNData

for some cases (for example, super resolution), the DNN model changes
the frame size which impacts the filter behavior, so the filter needs
to know the out frame size at very beginning.
Currently, the filter reuses DNNModule.execute_model to query the
out frame size, it is not clear from interface
