How often does this bug occurs?

always

Expected behavior

jpeg_enc_open shouldn't use a lot of memory on esp32-s3 with 8MB PSRAM.

Actual behavior (suspected bug)

When using JPEG_ENC_OPEN with the ESP32-CAMERA, an error occurs when the camera resolution is above FRAMESIZE_VGA, memory allocation fails.

Error logs or terminal output

JPEG_ENC: JPEG allocate memory failed, line 604

Steps to reproduce the behavior

Using older versions jpeg encoder of the esp_codec library is no problem.

Project release version

v5.3.1,v5.0

The memory management method in esp_new_jpeg has some differences compared to esp_jpeg.

Please provide details on the remaining system memory and image parameters at the time of the error.

1. Use the following code to print the remaining system memory

    ESP_LOGI("SYS", "Internal free heap size: %ld bytes", esp_get_free_internal_heap_size());
    ESP_LOGI("SYS", "PSRAM    free heap size: %ld bytes", esp_get_free_heap_size() - esp_get_free_internal_heap_size());
    ESP_LOGI("SYS", "Total    free heap size: %ld bytes", esp_get_free_heap_size());

2. Provide the jpeg_enc_config_t parameter of the jpeg_enc_open() function

typedef struct jpeg_info {
    int                 width;
    int                 height;
    jpeg_pixel_format_t src_type;
    jpeg_subsampling_t  subsampling;
    uint8_t             quality;
    jpeg_rotate_t       rotate;
    bool                task_enable;
    uint8_t             hfm_task_priority;
    uint8_t             hfm_task_core;
} jpeg_enc_config_t;

1.The remaining system memory before jpeg_enc_open：

I (23553) SYS: Internal free heap size: 71907 bytes
I (23553) SYS: PSRAM    free heap size: 4522297 bytes
I (23553) SYS: Total    free heap size: 4594204 bytes
E (23553) JPEG_ENC: JPEG allocate memory failed, line 604
E (23553) JPEG_ENC: JPEG encoder open fail. line 72
E (23553) to_jpg_new: jpeg_enc_open error: -1

I also found that the jpeg_enc_handle_t *jpeg_enc memory was not freed when the error was returned.

2.The jpeg_enc_config_t parameter: fb->width is 1600, fb->height is 1200.

    jpeg_enc_config_t jpeg_enc_cfg = 
    {
        .width = fb->width,
        .height = fb->height,
        .src_type = JPEG_PIXEL_FORMAT_RGB888,
        .subsampling = JPEG_SUBSAMPLE_420,
        .quality = 80,
        .rotate = JPEG_ROTATE_0D,
        .task_enable = false,
        .hfm_task_priority = 13,
        .hfm_task_core = 1,
    };
