您好，我使用jetson_mutimedia_api时发现。sample：06_jpeg_decode ：我传入一个格式被破坏的jpeg数据时，jpeg_read_header()函数会报错”Error: Parsing of stream failed”，但是程序捕获不到这个错误。紧接着在jpeg_read_raw_data函数内部就出现段错误。

我手动设置了cinfo.err的处理机制，还是捕捉不到这个错误，这样会导致我程序只要遇到错误的jpeg程序就会崩溃。

    m_cinfo.err = jpeg_std_error(&m_jerr.pub);
    m_jerr.pub.error_exit = rcu_jpeg_error_exit;
    m_jerr.pub.emit_message = rcu_jpeg_emit_message;

请帮我分析原因，我如何避免因为错误的文件格式而导致程序崩溃？

Hi,
Please attach the JPEG file and share the command of running 06 sample. We will set up AGX Thor developer kit and check.

Hi,

Please backup original and replace it with attached shared library under the /usr/lib/aarch64-linux-gnu/nvidia/ .

Below is the sha256sum value

sha256sum libnvmm_jpeg.so

Hi @chutianwei ,

If the attached library works well, please mark the solution ✅ and we could close the topics.

Thanks
