camera工程选择了JPEG模式之后，报错了 #7

Closed coollofty closed 4 years ago

coollofty commented 4 years ago

报错信息如下，持续的输出：

E (6077) jpeg: Image decoder: jd_prepare failed (6)

工程是：esp-dev-kits\esp32-s2-kaluga-1\examples\camera IDF版本：v4.2 esp-dev-kits版本：master最新 开发板：esp32-s2-kaluga-1

如果不选择jpeg模式就能正常显示了，那么请问这个错误是什么原因？

Hi @coollofty,

how did you fix this issue? I'm currently having the same problem. The example doesn't work when jpg mode is enabled.

If I print the cam_buf contents in jpg mode they are always the same:

I (1581) main: fc d8 fc e0 00 10 48 44 48 44 00 00 00 00 00 00 
I (1581) main: 00 00 00 00 fc d8 00 40 00 0c 08 08 08 08 08 0c 
I (1591) main: 08 08 08 0c 0c 0c 0c 10 1c 14 10 10 10 10 24 18 
I (1601) main: 1c 14 1c 2c 24 2c 2c 28 24 28 28 30 34 44 38 30 
I (1601) main: 30 40 34 28 28 3c 50 3c 40 44 48 4c 4c 4c 2c 38 
I (1611) main: 54 58 54 48 58 44 4c 4c 48 fc d8 00 40 00 0c 0c
....

Thanks!

据官方说可能是摄像头拔码开关的问题，我这边由于自己画了板子，没有使用官方的开发板了确实也就没有了上面的问题

I didn't find a solution. I haven't worked with the hardware again since then and don't see myself doing so in the near future.

coollofty's comment from google translate:

According to the official statement, it may be the problem of the camera's code switch. Since I drew the board by myself, I did not use the official development board, and the above problem would indeed be eliminated.

Looks like they worked with different hardware.
