/** Chunk of codestream data that is part of a code block */
Decoding: do not allocate memory for the codestream of each codeblock Currently we allocate at least 8192 bytes for each codeblock, and copy the relevant parts of the codestream in that per-codeblock buffer as we decode packets. As the whole codestream for the tile is ingested in memory and alive during the decoding, we can directly point to it instead of copying. But to do that, we need an intermediate concept, a 'chunk' of code-stream segment, given that segments may be made of data at different places in the code-stream when quality layers are used.

Decoding: do not allocate memory for the codestream of each codeblock Currently we allocate at least 8192 bytes for each codeblock, and copy the relevant parts of the codestream in that per-codeblock buffer as we decode packets. As the whole codestream for the tile is ingested in memory and alive during the decoding, we can directly point to it instead of copying. But to do that, we need an intermediate concept, a 'chunk' of code-stream segment, given that segments may be made of data at different places in the code-stream when quality layers are used. With that change, the decoding of MAPA_005.jp2 goes down from the previous improvement of 2.7 GB down to 1.9 GB.

Slight improvement in management of code block chunks Instead of having the chunk array at the segment level, we can move it down to the codeblock itself since segments are filled in sequential order. Limit the number of memory allocation, and decrease slightly the memory usage.

/** Reinitialize a segment */
Decoding: do not allocate memory for the codestream of each codeblock Currently we allocate at least 8192 bytes for each codeblock, and copy the relevant parts of the codestream in that per-codeblock buffer as we decode packets. As the whole codestream for the tile is ingested in memory and alive during the decoding, we can directly point to it instead of copying. But to do that, we need an intermediate concept, a 'chunk' of code-stream segment, given that segments may be made of data at different places in the code-stream when quality layers are used. With that change, the decoding of MAPA_005.jp2 goes down from the previous improvement of 2.7 GB down to 1.9 GB.
