I cannot reproduce your problem (for me, FFmpeg's libopenjpeg detection fails
due to --as-needed, but MPlayer's works fine), but I can at least post the
relevant lines from openjpeg.h (that do not exist in my older version):
OPJ_API opj_stream_t* OPJ_CALLCONV opj_stream_create_default_file_stream (FILE *
p_file, opj_bool p_is_read_stream);
OPJ_API opj_stream_t* OPJ_CALLCONV opj_stream_create_file_stream (FILE * p_file,
OPJ_UINT32 p_buffer_size, opj_bool p_is_read_stream);
