CMake Support && FPE on unknown address #6

Closed frokaikan closed 5 years ago

frokaikan commented 6 years ago

Now this project can only build on MS Windows with gcc/clang, I can't build it. So I write a CMakeLists.txt CMakeLists.txt to compile it on Linux. But when I run the binary I got this:

./ffjpeg -d input/lena.jpg 
AddressSanitizer:DEADLYSIGNAL
=================================================================

Sorry but I just forgot to upload my lena.jpg lena.zip

I've debugged and analysed the lena.jpg you provided.

I found out:

  1. the lena.jpg is a progressive jpeg file
  2. the file does not contain the AC huffman table.

so my code can not decode it correctly.

but this file can be open on windows Image viewer.
