By default, Espressif SoCs use TJpg decoder implemented in ROM code.
|
||||
If this feature is disabled, new configuration of TJpg decoder can be used.

help

Enable this option to support decoding JPEG images that lack an embedded Huffman table.
|
||||
When enabled, a default Huffman table is used during decoding, allowing the JPEG decoder to handle
|
||||
images without explicitly provided Huffman tables.
|
||||
|
||||
Note: Enabling this option increases ROM usage due to the inclusion of default Huffman tables.
