  • ffmpeg decode JPEG 2000 in multithread

    30 septembre 2015, par mattobob

    So, I have a Video-decoder written in c++ whit help of ffmpeg library, non problem till when it comes to decode JPEG 2000 frame in multi threads, in this case the image is discontinuous, I set the context to have even number of threads and to process image slices :

        m->context->thread_count = m_cfgHhiThreads->value();
    
    m->context->thread_type = FF_THREAD_SLICE;

    here is a sample image captured after decoding process (dimension is fine), this only happen if multithred is set enter image description here

    Question is, why is this happening ?

    FFMPEG does not report any error, it actually think that the image has been correctly decoded. It is also correctly decoded the problem is in slicing.
