Right. Without avs2 tag, MKV will use AVI compatible mode automatically I think.

This patch makes the ff_jpeg2000_cleanup
function take in an extra parameter which
indicates whether it is called from the
encoder or decoder.

This patch allows setting a compression ratio and to
set multiple layers. The user has to input a compression
ratio for each layer.
The per layer compression ration can be set as follows:
-layer_rates "r1,r2,...rn"
for to create 'n' layers.

Keeping only the latest packet fed to the decoder works only for decoders that
return a frame immediately after every consumed packet. Decoders that consume
several packets before they return a frame will fill said frame with properties
taken from the last consumed packet instead of the earliest.

Hi,
Unrolling by 4 the outer loop in yuv2planeX reduces the number of cache
accesses by 7.5%.
The values loaded for the filter are used in the 4 unrolled iterations and
avoids reloading 3 times the same values.
The performance was measured on an Arm64 Neoverse-N1 Graviton2 c6g.metal

It took me some time to figure out where this |RtmpSampleAccess packet came
from. It turns out that this is an undocumented AMF packet that is used to
transfer the state of the documented Client.audioSampleAccess and
Client.videoSampleAccess state to the client.
This post gave me some clues:
