Hello,
JPEG2000 uses .pgx format for conformance testing. Is it a good idea
to allow the ffmpeg
native decoder to have an option to dump .pgx files? This would help
with testing additions
to the code.

Hi there! First time contributor here.
I've made a filter for performing nonlinear stretching of videos,
also known as dynamic stretch and similar to GoPro's SuperView.
I left some questions as TODO's in the code that I hope you can help me answer.
Also, how do you run the test or see the out

The log2_chroma_wh is derived from the sample separations of the
codestream if the file is a j2k codestream. Not sure if sample
separation is same is subsampling and whether using sample
separation values from the codestream to determine pixel format.

libopenjpeg2000 uses ceiling division while dividing tile
co-ordinates with the sample separation. Also, corrections
were made to the WRITE_FRAME macro.

This patch removes a check which throws an error if
the log2 precinct width/height is 0. The standard allows
the first component to have 0 as the log2 width/height.

Given that AV1 only has exactly one sequence header, it is unnecessary
to copy the content of said sequence header into an intermediate dynamic
buffer; instead the sequence header can be copied from where it is in
the input buffer.
